Idle Prentices."

MARSTON, PHILIP BOURKE (1850-1887), English poet, was born in London on

the 13th of August 1850. His father, JOHN WESTLAND MARSTON (1819-1890),

of Lincolnshire origin, the friend of Dickens, Macready and Charles

Kean, was the author of a series of metrical dramas which held the stage

in succession to the ambitious efforts of John Tobin, Talfourd, Bulwer

and Sheridan Knowles. His chief plays were _The Patrician's Daughter_

(1841), _Strathmore_ (1849), _A Hard Struggle_ (1858) and _Donna Diana_

(1863). He was looked up to as the upholder of the outworn tradition of

the acted poetic drama, but his plays showed little vitality, and

Marston's reviews for the _Athenaeum_, including one of Swinburne's

_Atalanta in Calydon_, and his dramatic criticisms embodied in _Our

Recent Actors_ (1888) will probably claim a more enduring reputation.

His _Dramatic and Poetical Works_ were collected in 1876. The son,

Philip Bourke, was born in a literary atmosphere. His sponsors were

Philip James Bailey and Dinah Mulock (Mrs Craik). At his father's house

near Chalk Farm he met authors and actors of his father's generation,

and subsequently the Rossettis, Swinburne, Arthur O'Shaughnessy and

Irving. From his earliest years his literary precocity was overshadowed

by misfortunes. In his fourth year, in part owing to an accident, his

sight began to decay, and he gradually became almost totally blind. His

mother died in 1870. His _fiancée_, Mary Nesbit, died in 1871; his

closest friend, Oliver Madox Brown, in 1874; his sister Cicely, his

amanuensis, in 1878; in 1879 his remaining sister, Eleanor, who was

followed to the grave after a brief interval by her husband, the poet

O'Shaughnessy, and her two children. In 1882 the death of his chief

poetic ally and inspirer, Rossetti, was followed closely by the tragedy

of another kindred spirit, the sympathetic pessimist, James Thomson ("B.

V."), who was carried dying from his blind friend's rooms, where he had

sought refuge from his latest miseries early in June of the same year.

It is said that Marston came to dread making new friendships, for fear

of evil coming to the recipients of his affection. In the face of such

calamities it is not surprising that Marston's verse became more and

more sorrowful and melancholy. The idylls of flower-life, such as the

early and very beautiful "The Rose and the Wind" were succeeded by

dreams of sleep and the repose of death. These qualities and gradations

of feeling, reflecting the poet's successive ideals of action and

quiescence, are traceable through his three published collections,

_Songtide_ (1871), _All in All_ (1875) and _Wind Voices_ (1883). The

first and third, containing his best work, went out of print, but

Marston's verse was collected in 1892 by Mrs Louise Chandler Moulton, a

loyal and devoted friend, and herself a poet. Marston read little else

but poetry; and of poetic values, especially of the intenser order, his

judgment could not be surpassed in sensitiveness. He was saturated with

Rossetti and Swinburne, and his imitative power was remarkable. In his

later years he endeavoured to make money by writing short stories in

_Home Chimes_ and other American magazines, through the agency of Mrs

Chandler Moulton. His popularity in America far exceeded that in his own

country. His health showed signs of collapse from 1883; in January 1887

he lost his voice, and suffered intensely from the failure to make

himself understood. He died on the 13th of February 1887.

He was commemorated in Dr Gordon Hake's "Blind Boy," and in a fine

sonnet by Swinburne, beginning "The days of a man are threescore years

and ten." There is an intimate sketch of the blind poet by a friend,

Mr Coulson Kernahan, in _Sorrow and Song_ (1894), p. 127. (T. Se.)

MARSTON MOOR, BATTLE OF, was fought on the 2nd of July 1644 on a moor

(now enclosed) seven miles west of York, between the Royalist army under

Prince Rupert and the Parliamentary and Scottish armies under the earl

of Manchester, Lord Fairfax and Lord Leven. For the operations that

preceded the battle see GREAT REBELLION. Rupert had relieved York and

joined forces with the marquess of Newcastle's army that had defended

that city, and the Parliamentarians and Scots who had besieged it had

drawn off south-westward followed by the Royalists. On the morning of

the 2nd of July, however, Rupert's attack on their rearguard forced them

to halt and deploy on rising ground on the south edge of the moor, their

position being defined on the right and left by Long Marston and

Tockwith and divided from the Royalist army on the moor by a lane

connecting these two villages. The respective forces were--Royalists

about 18,000, Parliamentarians and Scots about 27,000. The armies stood

front to front. On the Royalist right was half the cavalry under Rupert;

the infantry was in the centre in two lines and the left wing of cavalry

was under General (Lord) Goring. The lane along the front was held by

skirmishers. On the other side the cavalry of the Eastern Association

under Lieut.-General Cromwell and that of the Scots under Major-General

Leslie (Lord Newark) formed the left, the infantry of the Eastern

Association under Major-General Crawford, of the Scots under Lord Leven,

and of the Yorkshire Parliamentarians under Lord Fairfax was in the

centre and the Yorkshire cavalry under Sir Thomas Fairfax was on the

right wing.

During the afternoon there was a desultory cannonade, but neither side

advanced. At last, concluding from movements in the enemy's lines that

there would be no fighting that day, Rupert and Newcastle strolled away

to their coaches and their soldiers dismounted and lay down to rest. But

seeing this Cromwell instantly advanced his wing to the attack (5 p.m.).

His dragoons drove away the skirmishers along the lane, and the line

cavalry crossed into the moor. The general forward movement spread along

the Parliamentary line from left to right, the Eastern Association

infantry being the first to cross the road. In Rupert's momentary

absence, the surprised Royalist cavalry could make no head against

Cromwell's charge, although the latter was only made piecemeal as each

unit crossed the lane and formed to the front. Rupert soon galloped up

with his fresh second line and drove back Cromwell's men, Cromwell

himself being wounded, but Leslie and the Scots Cavalry, taking ground

to their left, swung in upon Rupert's flank, and after a hard struggle

the hitherto unconquered cavalry of the prince was broken and routed.

Then, being unlike other cavalry of the time, a thoroughly disciplined

force, the Eastern Association cavalry rallied, leaving the pursuit to

the Scots light horse. On the Parliamentary right, Goring had swept away

the Yorkshire horse, and although most of his troopers had followed in

disorderly pursuit, Sir Charles Lucas with some squadrons was attacking

the exposed right of Leven's infantry. At the same time the

Parliamentary infantry had mostly crossed the lane and was fighting at

close quarters and suffering severely, Newcastle's north-country

"White-Coat" brigade driving back and finally penetrating their centre.

Lord Leven gave up the battle as lost and rode away to Tadcaster. But

the Scots on the right of the foot held firm against Lucas's attacks,

and Cromwell and Leslie with their cavalry passed along the rear of the

Royal army, guided by Sir Thomas Fairfax (who though wounded in the rout

of his Yorkshire horse had made his way to the other flank). Then, on

the ground where Goring had routed Fairfax, Cromwell and Leslie won an

easy victory over Goring's scattered and disordered horsemen. The

Eastern Association infantry had followed the horse and was now in rear

of the Royalists. The original Parliamentary centre of foot, a remnant,

but one containing only the bravest and steadiest men, held fast, and

soon the Royalist infantry was broken up into isolated regiments and

surrounded by the victorious horse and foot of the enemy. The

White-Coats retreated into an enclosure and there defended themselves to

the last man. The rest were cut down on the field or scattered in the

pursuit and at nightfall the Royalist army had ceased to exist. Some of

Rupert's foot regiments made their way to York, but the dispirited

garrison only held out for a fortnight. Rupert rallied some six thousand

of the men and escaped over the hills into Lancashire, thence rejoining

King Charles in the south. But the Northern army, the main hope of the

Royalist cause, was destroyed.

MARSUPIALIA (from Lat. _marsupium_, a "pouch," or "bag"), the group of

mammals in which the young are usually carried for some time after birth

in a pouch on the under-surface of the body of the female. The group,

which has also the alternative title of Didelphia, is by some

authorities regarded as a sub-class of the mammalia of equal rank with

the Monotremata, while by others it is brigaded with the placentals, so

that the two together form a sub-class of equal grade with the one

represented by the monotremes. There is much to be urged in favour of

either view; and in adopting the former alternative, it must be borne in

mind that the difference between monotremes and marsupials is vastly

greater than that which separates the latter from placentals. In

elevating the marsupials to the rank of a sub-class the name Metatheria

has been suggested as the title for the higher grade, with Marsupialia

as the designation for the single order by which they are now

represented. It is, however, less liable to cause confusion, and in many

other ways more convenient to employ the better known term Marsupialia

in both senses.

Marsupials may be defined as viviparous (that is non-egg-laying)

mammals, in which the young are born in an imperfect condition, and

almost immediately attached to the teats of the mammary glands; the

latter being generally enclosed in a pouch, and the front edge of the

pelvis being always furnished with epipubic or "marsupial" bones. As a

rule there is no allantoic placenta forming the means of communication

between the blood of the parent and the foetus, and when such a

structure does occur its development is incomplete. In all cases a more

or less full series of teeth is developed, these being differentiated

into incisors, canines, premolars and molars, when all are present; but

only a single pair of teeth in each jaw has deciduous predecessors.

The pouch from which the marsupials take their name is supported by the

two epipubic bones, but does not correspond to the temporary

breeding-pouch of the monotremes. It may open either forward or

backwards; and although present in the great majority of the species,

and enclosing the teats, it may, as in many of the opossums, be

completely absent, when the teats extend in two rows along the whole

length of the under-surface of the body. Whether a pouch is present or

not, the young are born in an exceedingly imperfect state of

development, after a very short period of gestation, and are immediately

transferred by the female parent to the teats, where they remain firmly

attached for a considerable time; the milk being injected into their

mouths at intervals by means of a special muscle which compresses the

glands. In the case of the great grey kangaroo, for instance, the period

of gestation is less than forty days, and the newly-born embryo, which

is blind, naked, and unable to use its bud-like limbs, is little more

than an inch in length.

As additional features of the sub-class may be mentioned the absence

of a corpus callosum connecting the right and left hemispheres of the

brain,[1] and of a fossa in the septum between the two auricles of the

heart. In the skull there are always vacuities, or unossified spaces

in the bones of the palate, while the "angle," or lower hind extremity

of each half of the lower jaw is strongly bent inwards so as to form a

kind of shelf, and the alisphenoid bone takes a share in the formation

of the tympanum, or auditory bladder, or bulla. Didelphia, the

alternative name of the group was given in allusion to the

circumstance that the uterus has two separate openings; while other

features are the inclusion of the openings of the alimentary canal and

the urino-genital sinus in a common sphincter muscle, and the position

of the scrotum in advance of the penis. The bandicoots alone possess a

placenta. Lastly the number of trunk-vertebrae is always nineteen,

while there are generally thirteen pairs of ribs.

As regards the teeth, in all cases except the wombats the number of

upper incisors differs from that of the corresponding lower teeth. As

already stated, there is no vertical displacement and succession of

the functional teeth except in the case of a single tooth on each side

of each jaw, which is the third of the premolar series, and is

preceded by a tooth having more or less of the characters of a molar

(see fig. 1). In some cases (as in rat-kangaroos) this tooth retains

its place and function until the animal has nearly, if not quite,

attained its full stature, and is not shed and replaced by its

successor until after all the other teeth, including the molars, are

in place and use. In others, as the thylacine, it is rudimentary,

being shed or absorbed before any of the other teeth have cut the gum,

and therefore functionless. It may be added that there are some

marsupials, such as the wombat, koala, marsupial ant-eater and the

dasyures, in which no such deciduous tooth, even in a rudimentary

state, has been discovered. In addition to this replacement of a

single pair of functional teeth in each jaw, it has been discovered

that marsupials possess rudimentary tooth-germs which never cut the

gum. According to one theory, these rudimentary teeth, together with

the one pair of functional teeth in each jaw that has vertical

successors, represent the milk-teeth of placental mammals. On the

other hand, there are those who believe that the functional dentition

(other than the replacing premolar and the molars) correspond to the

milk-dentition of placentals, and that the rudimentary tooth-germs

represent a "prelacteal" dentition. The question, however, is of

academic rather than of practical interest, and whichever way it is

answered does not affect our general conception of the nature and

relationships of the group.

[Illustration: FIG. 1.--Teeth of Upper Jaw of Opossum (_Didelphys

marsupialis_), all of which are unchanged, except the third premolar,

the place of which is occupied in the young animal by a molariform

tooth, represented in the figure below the line of the other teeth.]

Unfortunately the homology of the functional series does not by any

means end the uncertainty connected with the marsupial dentition; as

there is also a difference of opinion with regard to the serial

homology of some of the cheek-teeth. For instance, according to the

older view, the dental formula in the thylacine or Tasmanian wolf is

i. 4/3, c, 1/1 p. 3/3, m. 4/4 = 46. On the other hand, in the opinion

of the present writer, this formula, so far as the cheek-teeth are

concerned, should be altered to p. 4/4, m. 3/3, thus bringing it in

accord, so far as these teeth are concerned, with the placental

formula, and making the single pair of replacing teeth the third

premolars. It may be added that the formula given above shows that the

marsupial dentition may comprise more teeth than the 44 which form the

normal full placental complement.

As regards geographical distribution, existing marsupials, with the

exception of two families, _Didelphyidae_ and _Epanorthidae_, are mainly

limited to the Australian region, forming the chief mammalian fauna of

Australia, New Guinea, and some of the adjacent islands. The

_Didelphyidae_ are almost exclusively Central and South American, only

one or two species ranging into North America. Fossil remains of members

of this family have also been found in Europe in strata of the Oligocene

period.

_History._--The origin and evolution of the Australian marsupials have

been discussed by Mr B. A. Bensley. In broad contrast to the views of Dr

A. R. Wallace, this author is of opinion that marsupials did not effect

an entrance into Australia till about the middle of the Tertiary period,

their ancestors being probably opossums of the American type. They were

then arboreal; but they speedily entered upon a rapid, although

short-lived, course of evolution, during which leaping terrestrial forms

like the kangaroos were developed. The short period of this evolution is

at least one factor in the primitive grade of even the most specialized

members of the group. In the advance of their molar teeth from a

tritubercular to a grinding type, the author traces a curious

parallelism between marsupials and placentals. Taking opossums to have

been the ancestors of the group, the author considers that the present

writer may be right in his view that marsupials entered Australia from

Asia by way of New Guinea. On the other hand there is nothing absolutely

decisive against their origin being southern.

Again, taking as a text Mr L. Dollo's view that marsupials were

originally arboreal, that, on account of their foot-structure, they

could not have been the ancestors of placentals, and that they

themselves are degenerate placentals, Mr Bensley contrasts this with

Huxley's scheme of mammalian evolution. According to the latter, the

early monotremes which became specialized into modern monotremes, gave

rise to the ancestors of the modern marsupials; while the modern

placentals are likewise an offshoot from the ancestral marsupial stock.

This phylogeny, the author thinks, is the most probable of all. It is

urged that the imperfect placenta of the bandicoots instead of being

vestigial, may be an instance of parallelism, and that in marsupials

generally the allantois failed to form a placental connexion. Owing to

the antiquity of both placentals and marsupials, the arboreal character

of the feet of the modern forms of the latter is of little importance.

Further, it is considered that too much weight has been assigned to the

characters distinguishing monotremes from other mammals, foetal

marsupials showing a monotreme type of coracoid, while it is probable

that in the long run it will be found impossible to maintain the

essential dissimilarity between the milk-glands of monotremes and other

mammals.

Another view is to regard both marsupials and placentals as derivates

from implacental ancestors more or less nearly related to the creodont

carnivora, or possibly as independently descended from anomodont

reptiles (see CREODONTA). Finally, there is the hypothesis that

marsupials are the descendants of placentals, in which case, as was

suggested by its discoverer, the placenta of the bandicoots would be a

true vestigial structure.

_Classification._

Existing marsupials may be divided into three main divisions or

sub-orders, of which the first, or Polyprotodontia, is common to America

and Australasia; the second, or Paucituberculata, is exclusively South

American; while the third, or Diprotodonts, is as solely Australasian

inclusive of a few in the eastern Austro-Malayan islands.

1. _Polyprotodonts._--The Polyprotodonts are characterized by their

numerous, small, sub-equal incisors, of which there are either five or

four pairs in the upper and always three in the lower jaw, (fig. 2)

and the generally strong and large canines, as well as by the presence

of from four to five sharp cusps or tubercles on the crown of the

molars. The pouch is often absent, and may open backwards. For the

most part the species are carnivorous or insectivorous.

[Illustration: From Flower, _Quart. Jour. Geol. Soc._

FIG. 2.--Front View of Skull of the Tasmanian Devil (_Sarcophilus

ursinus_) to exhibit polyprotodont type of dentition.]

The first family is that of the true or American

opossums--_Didelphyidae_, in which there are five pairs of upper

incisors, while the feet are of the presumed primitive arboreal type,

the hind foot having the four outer toes sub-equal and separate, with

the first opposable to them all. With the exception of the

water-opossum, forming the genus _Chironectes_, all the living members

of the family may be included in the genus _Didelphys_. The latter

may, however, be split up into several sub-generic groups, such as

_Metachirus_, _Philander_, _Marmosa_ (_Micoureus_ or _Grymaeomys_),

_Peramys_, _Dromiciops_, &c. The small South American forms included

in _Marmosa_, which lack the pouch, and have numerous teats, and molar

teeth of a primitive type, are doubtless the most generalized

representatives of the group (see OPOSSUM; and WATER-OPOSSUM).

Nearly allied is the Australian family _Dasyuridae_, characterized by

the presence of only four pairs of upper incisors, the generally small

and rudimentary condition of the first hind toe, which can but seldom

be opposed to the rest, and the absence of prehensile power in the

tail; the pouch being either present or absent, and the fore feet

always five-toed. The stomach is simple, and there is no caecum to the

intestine, although this is present in the opossums.

The largest representative of the family is the Tasmanian wolf, or

thylacine, alone representing the genus _Thylacinus_, in which the

dentition numbers i. 4/3, c. 1/1, p. 4/4, m. 3/3 = 46; with the

incisors small and vertical, the outer one in the upper jaw being

larger than the others. Summits of the lower incisors, before they are

worn, with a deep transverse groove, dividing it into an anterior and

a posterior cusp. Canines long, strong and conical. Premolars with

compressed crowns, increasing in size from before backwards. Molars in

general characters resembling those of _Sarcophilus_, but of more

simple form, the cusps being less distinct and not so sharply pointed.

Deciduous molar very small, and shed before the animal leaves the

mother's pouch. General form dog-like, with the head elongated, the

muzzle pointed, and the ears moderate, erect and triangular. Fur short

and closely applied to the skin. Tail of moderate length, thick at the

base and tapering towards the apex, clothed with short hair. First

hind toe (including the metacarpal bone) absent. Vertebrae: C. 7, D.

13, L. 6, S. 2, Ca. 23. Marsupial bones unossified. The gradual

passage of the thick root of the tail into the body is a character

common to the Tasmanian wolf and the aard-vark, and may be directly

inherited from reptilian ancestors (see THYLACINE).

[Illustration: FIG. 3.--The Tasmanian Wolf, or Thylacine (_Thylacinus

cynocephalus_).]

The next genus is represented solely by the Tasmanian devil,

_Sarcophilus_ (or _Diabolus_) _ursinus_, a medium-sized animal with a

dental formula similar to that of the dasyures, but with teeth (fig.

2) approximating to those of the thylacine, though markedly different

in details. The first hind toe is absent.

In the "native cats," or dasyures, constituting the genus _Dasyurus_,

the dental formula is i. 4/3, c. 1/1, p. 3/3, m. 3/3: total 42. The

upper incisors are nearly equal and vertical, with the first slightly

longer, narrower, and separated from the rest. Lower incisors sloping

forward and upward. Canines large and sharply pointed. First two

premolars with compressed and sharp-pointed crowns, and slightly

developed anterior and posterior accessory basal cusps. Molars with

numerous sharp-pointed cusps. In the upper jaw the first two with

crowns having a triangular free surface; the last small, simple,

narrow and placed transversely. In the lower jaw the molars more

compressed, with longer cusps; the last not notably smaller than the

others. Ears of moderate size, prominent and obtusely pointed. First

hind toe rudimentary, clawless or absent; its metatarsal bone always

present. Tail generally long and well clothed with hair. Vertebrae: C.

7, D. 13, L. 6, S. 2, Ca. 18-20 (see DASYURE).

The genus _Phascologale_ comprises a number of small marsupials, none

exceeding a rat in size, differing from the dasyures in possessing an

additional premolar--the dentition being i. 4/3, c. 1/1, p. 4/4, m.

3/3: total 46--and in having the teeth generally developed upon an

insectivorous rather than a carnivorous pattern, the upper middle

incisors being larger and inclined forward, the canines relatively

smaller, and the molars with broad crowns, armed with prickly

tubercles. The muzzle is pointed. Ears moderately rounded, and nearly

naked. Fore feet with five sub-equal toes, with compressed, slightly

curved pointed claws. Hind feet with the four outer toes sub-equal,

with claws similar to those in the fore feet; the first toe almost

always distinct and partially opposable, though small and nailless,

sometimes absent.

In some respects intermediate between the preceding and the next genus

is _Dasyuroides byrnei_, of Central Australia, an animal of the size

of a rat, with one lower premolar less than in _Phascologale_, without

the first hind toe, and with a somewhat thickened tail. The pouch is

incomplete, with two lateral folds, and the number of teats six.

_Sminthopsis_ includes several very small species, with the same

dental formula as _Phascologale_, but distinguished from that genus by

the narrowness of the hind foot, in which the first toe is present,

and the granulated or hairy (in place of broad, smooth and naked)

soles. A pouch is present, and there are eight or ten teats. Nearly

allied is the jumping _Antechinomys laniger_, of East Central

Australia, an elegant mouse-like creature, with large oval ears,

elongated limbs, a long and tufted tail and no first hind toe. In

connexion with the large size of the ears is the excessive inflation

of the auditory bulla of the skull.

From all other members of the family the marsupial, or banded,

ant-eater (_Myrmecobius fasciatus_) differs by the presence of more

than seven pairs of cheek-teeth in each jaw, as well as by the

exceedingly long and protrusile tongue. Hence it is made the type of a

distinct sub-family, the _Myrmecobiinae_, as distinct from the

_Dasyurinae_, which includes all the other members of the family. From

the number of its cheek-teeth, the banded ant-eater has been regarded

as related to some of the primitive Jurassic mammals; but this view is

disputed by Mr Bensley, who regards this multiplicity of teeth as a

degenerate feature. On the other hand, it is noteworthy that this

marsupial retains in its lower jaw the so-called mylo-hyoid groove,

which is found in the aforesaid Jurassic mammals. _Myrmecobius_ has a

total of 52 or 54 teeth, which may be classed as i. 4/3, c. 1/1, p. +

m. (8 or 9)/(8 or 9). The teeth are all small and (except the four

posterior inferior molars) separated from each other by an interval.

Head elongated, but broad behind; muzzle long and pointed; ears of

moderate size, ovate and rather pointed. Fore-feet with five toes, all

having strong pointed, compressed claws, the second, third and fourth

nearly equal, the fifth somewhat and the first considerably shorter.

Hind-feet with no trace of first toe externally, but the metatarsal

bone is present. Tail long, clothed with long hairs. Fur rather harsh

and bristly. Female without pouch, the young when attached to the

nipples being concealed by the long hair of the abdomen. Vertebrae: C.

7, D. 13, L. 6, S. 3, Ca. 23. The single species, which is a native of

western and southern Australia, is about the size of an English

squirrel, to which its long bushy tail gives it some resemblance; but

it lives entirely on the ground, especially in sterile sandy

districts, feeding on ants. Its prevailing colour is chestnut-red, but

the hinder part of the back is marked with broad, white, transverse

bands on a dark ground.
