GENERAL NOTICES.

_On the South African Frontier_[H] is a narrative of the experiences

and observations of the author, Mr. _William Harvey Brown_, partly as

naturalist of the United States Government Eclipse-observing

Expedition of 1889 to the west coast of Africa, and partly as a

resident in various occupations for seven years in Rhodesia. The

principal object in composing it was to give American readers a

clearer idea of English operations in conquest and colonization on the

South African frontier than it is possible to glean from current

fragmentary accounts. The author served his apprenticeship at natural

history collecting under Prof. L. L. Dyche, of the University of

Kansas, and Mr. W. T. Hornady, of the New York Zoölogical Gardens, and

was recommended by Mr. Hornady to the Government for the Eclipse

Expedition. He sailed first to Freetown, then to St. Paul de Loanda,

where he spent a few weeks collecting, establishing his headquarters

at Bishop Taylor's American Methodist Self-supporting Mission. Thence,

after a short attack of African fever, he proceeded to Cape Town,

where he was attacked by the other sort of African fever--"an

irresistible longing to penetrate the Dark Continent for purposes of

exploration and of observing both man and Nature." He made the journey

overland to Mafeting and to the Mashona country, in the region of

which he spent seven years as "game-hunter, gold-seeker, landowner,

citizen, and soldier," observing and participating in the settlement

and early development of the new state of Rhodesia. The larger part of

the book is devoted to his adventures and observations, "travel,

collecting, hunting, prospecting, farming, scouting, fighting," and

seeing pioneer life. Two chapters are devoted to ethnology. The race

problems which arise during the stage of transition from barbarism,

the agricultural and mineral resources of Rhodesia, and its prospects

and possibilities, are discussed.

A very handsome book, in what to many are the most graceful and

interesting forms of vegetable life, is Mrs. _Parsons's How to Know

the Ferns_.[I] The name of the author is new, but the author herself

is a familiar friend to all lovers of American field and wild-wood

life, for she is none other than Mrs. William Starr Dana, who had

already given us How to Know the Wild Flowers and According to Season.

In this book she does as she did with regard to the wild

flowers--takes her readers to the haunts of the ferns and into their

company, introduces us to them, and before she is done makes us well

acquainted with them. "It seems strange," she says, "that the

abundance of ferns everywhere has not aroused more curiosity as to

their names, haunts, and habits." Possibly it is because they are so

common that we are not at pains to seek greater intimacy with them.

Then, they depend on the beauty of graceful proportion, which is less

obvious to careless eyes than that of color. First, Mrs. Parsons

discourses of Ferns as a Hobby, and the pleasure we may derive from

them; then she tells when and where to find them, defines the terms

used in speaking of them, explains their fertilization, development,

and fructification, gives a list of notable fern families and

descriptions of the American ferns classified into eight groups

according to the arrangement of their spores, and completes the work

with indexes of Latin and of English names and of technical terms.

_The Microscopy of Drinking Water_[J] is intended by Mr. _Whipple_

primarily to serve as a guide to the water analyst and the water-works

engineer by describing the methods of microscopic examination,

assisting in the identification of the common microscopic organisms

found in drinking water, and interpreting the results in the light of

environmental studies. A second purpose is to stimulate a greater

interest in the study of microscopic aquatic life and general

limnology (the lessons of lakes and ponds) from the practical and

economic point of view. The work is elementary in character.

Principles are stated and illustrated, but the last ten years'

accumulations of data are not otherwise attacked. The illustrations

have been largely drawn from Massachusetts cases, from which there may

be differences elsewhere, but not very great as to microscopic

organisms. The latter half of the book is devoted to descriptions of a

limited number of organisms, chosen for the most part from those

commonest to the water supplies of New England, and those that have

best illustrated the more important groups of microscopic animals and

plants. Most of the illustrations have been drawn from living

specimens or photomicrographs of such, but some are reproduced from

other sources.

Whipple. New York: John Wiley & Sons. Pp. 300, with nineteen

It is evidence of appreciation of Dr. _Wetterstrand's Hypnotism and

its Application to Medicine_[K] that, written in Swedish, it has been

translated into German and Russian, and now into English. The German

work, from which the present translation is made, was enlarged from

the original, and embodied the results of additional experience. The

author disavows the intention of writing a manual or text-book, and

modestly assumes only to have given "unpretentious notes by a

physician who, under the pressure of a fatiguing and engrossing

practice, has not been able to develop his rich material into a more

complete form." The book is characterized by the translator as more

practical than theoretical, and as offering the results of

conscientious and able observation. Hypnosis is defined by Dr.

Wetterstrand as embracing a number of various conditions of the

nervous system, which can be produced in different ways. "We recognize

phases of the greatest variety, from a slight heaviness in the limbs,

the most superficial somnolence enabling the hypnotized subject to

hear and perceive the least noise, to the deepest sleep, from which

the greatest disturbance can not awake him, and wherein every

sensation disappears and permits the most serious surgical operation

without pain." The author believes that the majority of people can be

brought into any of these conditions, but the methods and degrees of

difficulty of the process are various. "Liébeault distinguishes five

degrees in hypnotic sleep, Bernheim nine; but Wetterstrand thinks they

may all be grouped under three. Suggestive therapeutics is regarded as

by no means a panacea, but it succeeds in cases where other methods

have failed," and, as Bernheim says, "often it produces miracles."

After an outline of the general principles of the subject the author

passes on to describe some diseases and morbid conditions in which he

has employed hypnotism with the greatest results, culling from his

notes, as impartially as possible, both successful attempts and

failures. The cases include insomnia, the list of nervous diseases,

drug diseases, consumption, rheumatic, heart, and other organic

diseases, and functional affections; with the use of suggestive

therapeutics in operations, obstetrics, and on some other occasions.

Dr. Petersen's medical letters on hypno-suggestion, etc., added to Dr.

Wetterstrand's work, are intended to give a succinct idea of the

present status of practical psychic therapeutics, as based on the

observation of clinical facts. They relate to suggestive treatment in

reform work, post-hypnotic responsibility, and music in hospitals.

The original object of Mr. _Henry Rutgers Marshall's_ essay on

_Instinct and Reason_[L] was to present a conception of religion. In

attempting to make his argument convincing he found it necessary to

deal with questions which did not at first appear to relate to this

subject, whereby the study of religion, though still the most

important and interesting matter considered, is made to appear

subsidiary to the treatment of instinct and reason. Believing that

activities so universal in man as those which express his religious

life must be significant in relation to his biological development,

the author has attempted to outline a theory that will account for

their existence and explain their biological import. In order to

present this clearly he has made a special study of instinct and the

relation of its activities with religious activities in general. This

has naturally led to the study of impulse, and thus to a consideration

of moral standards. The study of reason, too, has been found

appropriate in connection with the consideration of the nature of

religion. The genesis of religious customs and beliefs is touched upon

only so far as seems necessary for the elucidation of other parts of

the treatise. Concerning the relation of religion and morals, the

author finds that religion teaches us to listen to the past, and gives

enthusiasm to do the work commended by the "voice" of that past; it

gives us the basis for the perfection of our moral code, but it does

not give us this perfect moral code itself. When reason and the

religious instinct are opposed we should, after reverent and full

consideration, act in accord with reason, but should be cautious in

guiding others that way, for the chances are decidedly that we are

wrong, and "the rule of action which will best satisfy conscience,

which will produce the closest correspondence between our action as

viewed in retrospect and our most permanently efficient impulse

series, is one which is based upon the religious instinct, and which

involves the presence in mind of the sense of duty."

Mr. _Arthur Berry_ has undertaken, in his _Short History of

Astronomy_,[M] to give an outline of the history of the science from

the earliest times in a form intelligible to readers who have no

special knowledge of astronomy or mathematics. Some compression having

been necessary, it has been found possible to omit a considerable

number of details which might receive treatment, and indeed would

often require it in a treatise on the science. The author has

deliberately abstained from giving any connected account of the

astronomy of the Egyptians, Chaldeans, Chinese, and other peoples who

are usually supposed to have had a share in the early development of

star-lore. Accounts of scientific instruments, except in a few simple

and important cases, are omitted. But little is said of scientific

discoveries that have to be described in technical mathematical

language, and of speculative theories that have not been established

or refuted. On the other hand, whatever pertains to the real history

of astronomy has been given with sufficient fullness to make it plain;

the principles which are illustrated by enormous masses of

observations that there is no room to record; short biographical

sketches of leading astronomers other than living ones; a considerable

number of dates, such as those of the births and deaths of

astronomers; and even descriptions of such obsolete theories as appear

to form an integral part of astronomical progress. Among the

illustrations are portraits of a few of the eminent astronomers of the

past.

The special articles in the _Bulletin of the Department of Labor_,

Nos. 18 and 19, are Wages in the United States and Europe, 1870 to

1898, in the September number, and Mr. Dunham's paper on The Alaskan

Gold Fields and the Opportunities they offer for Capital and Labor,

and Mutual Relief and Benefit Associations in the Printing Trade, by

W. S. Wandly, in the number for November.

The Rev. Dr. _Adam Miller_ is a retired minister who has devoted his

leisure hours to the study of sunshine, in which he has included all

that properly belongs to the sun. He has read the standard works on

astronomy, and some, but apparently not all, the later results for

comparison, it seems, rather than information, and he has performed

some original and ingenious experiments with the sunlight. His views,

therefore, as expressed in _The Sun an Electric Light_ (Chicago), are

his own. He has come to the conclusion that the material theories of

the origin of the sun's light and heat do not account for the facts,

and are therefore insufficient if not wrong; postulates a theory that

the phenomena are matters of electric action made perceptible to us by

refraction through the atmosphere, and makes an unnecessary and

inconsequent attack on the theory of the conservation of forces. When

Dr. Miller assumes that his views of the insufficiency of present

theories and of the electrical nature of the sun's action are new, he

shows that he is not fully read up in the current literature on the

subject. The insufficiency of present views is confessed, and the

discussions of the subject with the various suppositions which he

criticises are efforts to find better explanations. The causal

identity of electricity, heat, and certain other forces is accepted.

But, given that electrical action is the basis of it all, what then?

Philosophers know of no way of maintaining electric action except

through material processes, and the way they are replenished to keep

it up is as hard to find out as would be the way fuel is supplied to

keep up a solar fire.

A pamphlet entitled _The Story of the Rise of the Oral Method in

America_ (of Instructing the Deaf and Dumb) _as told in the Writings

of the late Hon. Gardner G. Hubbard_, compiled by Mrs. _M. Gardner

Bell_, reveals a seeming indolence in the early instructors of the old

method that is hardly creditable to their energy in investigation.

When deaf-mute instruction was first projected here, a teacher was

sent over to Europe to learn the best methods. Denied access to

schools in London and Edinburgh, where articulation systems were

taught, he went to Paris, found the Abbé de l'Epée's sign language

there and brought it over. This and the finger language held sway in

our schools for many years, while the possibility of teaching

articulation to the deaf was denied. It required long-persistent

effort on the part of a few men who refused to have their deaf

children taught these systems and consequently isolated from their

fellow-men to secure a recognized place for oral schools. The story of

the struggle is told in Mrs. Bell's pamphlet.

The widespread ignorance and superstition with which even to-day the

practicing physician has to contend are hardly conceivable by an

outsider. The conditions under which a doctor knows his patients are

just those calculated to bring out the weak spots in their mental

organization, and the absurd notions which still have a foothold in

many minds are a constant source of wonder to the speculative doctor.

These superstitions are so widespread and so frequently dangerous to

the whole community, as well as the individual himself, that anything

which is calculated to improve matters, however so little, should be

welcomed with open arms. _Dr. Therne_, by _H. Rider Haggard_, is aimed

at the antivaccinators, and by means of a not uninteresting story

points out the serious consequences which a general belief in this

absurd crusade brought to an English city. The author labels his story

as an attempt to forecast the "almost certain issue of the recent

surrender of the English Government leaders to the clamor of the

antivaccinationists."

The annual number of the _Cumulative Index_ for 1898, constituting the

third annual volume, is a book of seven hundred and ninety-two pages,

and includes one hundred periodicals. It indexes--by authors, titles,

and subjects, including reviews and portraits--what is important in

the monthly and part of that in the weekly publications of the year.

Special attention is given to portraits, reviews, and necrology. The

Index is a very useful publication to writers and students of every

sort, recording the articles as they appear month by month in a form

that makes the knowledge of them easily accessible to one who seeks

it. The numbers succeeding the first number of the volume include,

besides their own fresh matter, that which has appeared in two or

three previous numbers, saving the necessity of hunting up scattered

editions. The annual volume contains all for the year. The Index is

edited in the Public Library of Cleveland, Ohio, and is published by

the Holman-Taylor Company in the same city.

Two papers bearing upon instruction of the deaf, published by the

Volta Bureau, Washington, are statistics, by Alexander G. Bell, of the

relative use in the United States of the several methods, and a

collection of _International Reports of Schools for the Deaf_. The

latter paper contains reports from sixteen countries.
