Professor Whewell in an Essay on the Employment of Notation in

Chemistry, observes, “I have no hesitation in saying, that in

mineralogy it is utterly impossible to express clearly, or to reason

upon, the chemical constitution of our substances, without the

employment of some notation or other. Every one who makes the trial

will find that, without a notation, his attempts to compare the

composition of different minerals will be confused and fruitless, and

that, by employing symbols, his reasonings may easily be made brief,

clear, and systematic.”

After criticising the foreign notation as being grossly anomalous and

defective, he adds the following list, which he hopes he has shown to

be mathematically consistent and chemically useful. He has used the

atomic composition adopted by Dr. Turner in his Chemistry.

Berzelius represents water (_aqua_) by _Aq_; for the sake of

simplicity Whewell says he has used _q_. He also observes, “In the

notation of Berzelius, the atoms of oxygen are indicated by dots

placed over the symbol of the base. Thus, _[..]fe_, _[...]fe_ are

the protoxide and peroxide of iron, which he considers as having two

and three atoms of oxygen respectively. This notation is compact

and simple, but it is not consistent with algebraical rule, so far

as the oxygen is concerned; and I conceive that, if this element

be explicitly expressed, it ought to be done in the manner I have

recommended, _fe_ + 2 _o_, _fe_ + 3 _o_, &c.”--_Journals of Royal

Institution._

I have omitted Professor Whewell’s reasons, which he gives to show

the superiority of his notation over those of foreign nations

and that of Berzelius, as they are not of practical utility in

printing; but I have given his list, which will be useful in printing

mineralogical works in cases where the copy may be bad.

FORTY-EIGHTMO.

A sheet of paper folded into forty-eight leaves, or ninety-six pages.

FORTYMO.

A sheet of paper folded into forty leaves, or eighty pages.

FOUL PROOF.

When a proof has many faults marked in it.--_M._ Pressmen are also in

the habit of calling the first proof a _Foul Proof_; and frequently

they pull it so as to justify the epithet.

FOUL STONE.

After imposing or correcting, if a compositor leave any thing upon

the imposing stone, except the mallet, shooting stick, and planer, it

is termed a foul stone; which in many houses subjects him to a fine.

FOUNT,

is the whole number of letters that are cast of the same body and

face at one time.--_M._ Moxon says this word is properly Fund.

FOUNT CASES.

Cases of larger proportions than those used to compose from, which

are kept to contain the surplus sorts of a fount until they are

required for use. In these cases they are more accessible than when

put into coffins and baskets according to the old plan, and are not

so likely to be mislaid.

FRACTIONS.

A fraction is part of a unit, and is written with two figures, one

above the other, with a line between them: thus, ¼, ⅚, ⅜. The upper

figure is called the numerator, and the lower figure the denominator.

The denominator shows how many parts the unit is divided into; and

the numerator, how many of those parts the fraction represents. A

proper fraction is when the numerator is less than the denominator.

An improper fraction is when the numerator is equal to, or greater

than the denominator.

A compound fraction is the fraction of a fraction, and is known by

the word, of, between the parts; as, ½ of ⅔ of 7/9 of 8/17. A mixed

number is composed of a whole number and fraction; as, 8-3/7, 17½. A

mixed fraction is when the numerator or denominator has a fractional

part; thus, 7⅔/4, 4/7⅔; or, when both of them have fractional parts;

as 5⅓/7⅕.

The fractions cast in one piece to a fount are ⅛, ¼, ⅜, ½, ⅝, ¾, ⅞.

Fractions are also cast in two pieces, from Brevier to English; when

wanted larger, they may be formed of figures of small proportionate

size, with a rule between the numerator and denominator.

This rule in separate fractions is now generally cast on the piece

containing the denominator, above the figure, thus, 1̅ 2̅ 3̅ 4̅ 5̅ 6̅

7̅ 8̅ 9̅ 0̅; but in improper fractions, where the numerator contains

more figures than the denominator, as 3848/21, this rule will not

cover the whole of the numerator, therefore it would be necessary, to

be able to compose fractions in a perfect manner, to have the rule

also cast under the numerator, according to the old plan, so as to

meet both cases, otherwise either the proper fraction or the improper

fraction must be deficient 21/3848.

FRAGMENTS.

After the body of a work, and the index are composed, the title,

preface, contents, &c. are proceeded with. If there be any pages

beyond the concluding sheet, they are now imposed together to save

presswork, and also warehouse work; and these pages are called

_Fragments_.

FRAME.

Made of deal wood, on which the cases are placed to be composed from.

[Illustration: Frame to hold cases]

By the annexed engraving it will be perceived, that the upper and

lower cases are placed upon the frame, not in a horizontal, but

sloping position, as two inclined planes, the upper case being

at a greater angle than the lower, which brings the more distant

boxes nearer to the compositor and thus expedites the work: this

arrangement occupies less room, and allows a greater number of frames

to stand in a given length.

The cases rest on a rail at each end, and in the middle there are

generally two rails, six or seven inches apart, for the inside end

of each case to rest on. There is frequently a piece of board nailed

to the bottom of these rails, which thus forms a depository for page

cords, copy that is not in use, and other small matters: this is

called a _Well_.

Frames are always placed with one end next the window, so that the

compositor when at work may stand with his left hand to the light;

thus he enjoys the full benefit of the light in picking up the

letters with his right hand. They are usually made to contain two

cases in length, which are generally a pair of Roman and a pair of

Italic cases, so that the compositor has not to go out of his frame

when he wants to compose a few words in Italic.

There is a rather strong nail driven into each end rail and each

middle rail for the bottom of the upper cases to rest upon, leaving

sufficient room for the lower cases to be lifted out when necessary.

The dimensions of a frame are--height of back, 4 feet 6 inches;

height of front, 3 feet 6 inches; width, 1 foot 10 inches; length, 4

feet 10 inches.

In a composing room, where there was plenty of room, I have seen the

frames made to contain three cases in length; this is a convenience,

as it allows the compositor to have up an additional pair of cases

for his notes.

FRENCH RULES.

Pieces of Brass, letter high, of different lengths and thicknesses,

on which are filed various dashes, swelling in the middle. They are

used to separate parts of a discourse; or are placed after certain

lines of capitals in titles and jobs, &c. They are also called _Swell

Rules_.

FRENCH WORDS AND PHRASES. _See_ PHRASES.

FRIAR.

When some parts of a ball or roller do not take the ink, so that

it does not adhere to the surface, the parts of the form that come

in contact with them will be deficient of ink, and the paper when

printed will, in those places, be either white or of a pale colour:

these white or pale patches are called _Friars_, as the black

patches, from too great a quantity of ink on particular places, are

called _Monks_.

FRISKET.

A thin iron frame, covered with paper, and connected temporarily with

the tympan, by means of joints attached to it and the headband of the

tympan, having iron pins to slip into them. The parts that are to be

printed are cut out of the paper covering; it turns down upon the

paper to be printed, which is laid upon the tympan, keeps it flat to

its place, preserves the margin clean, and raises it from the form

after it is printed. _See_ FRISKET BUTTON.

Each press in a printing office should have five or six friskets

attached to it, of at least three sizes--Demy, as the standard size

of paper; a size smaller; and a size sufficient for the largest form

the press will print, for it is very inconvenient, and a loss of

time, when the pressmen have to cover a frisket and cut it out for

every form they lay on: and more particularly when regular work is

in the house, and the same frisket will answer for many succeeding

forms. It is adviseable, where it is practicable, to have the frisket

joints at all the presses of one pattern, so that every frisket may

be available at any of the presses.

A pressman should never pull an impression from a form, without being

certain that the frisket is large enough, and that it does not rest

on the edges of the types, which would be destructive to them.

FRISKET BUTTON.

A button screwed on the offside of the tympan near the bottom, to

turn over the frisket and keep it close to the tympan in turning

down.

This button is only used when superior work is printing: it prevents

the sheet from touching the form partially, and also from slipping,

by confining it flat to the tympan, and thus tends to make better

work, and prevent waste; but it cannot be used where despatch is

required.

FRISKET JOINTS.

Two joints of the simplest construction, by which the frisket is

attached to the tympan by means of two pins, made with a head to

each, so that they can easily be taken out with the fingers; they are

inserted between the joints, and thus the heads face each other.

It is customary to place these joints on the flat part of the

headband of the tympan, which, when a large form is on the press,

and the rim of the chase is broad, rest upon, and prevent the form

receiving the effect of the pull. I have known great inconvenience

arise from this cause, in very superior work, where the chase filled

the press, and could not be moved to get rid of this grievance. The

joints should be taken off, and fixed to the extreme edge of the

headband, by which means they will extend beyond the chase, and the

evil be completely remedied. Where the frisket is fixed on centres

this inconvenience does not exist.

FRISKET PINS.

Two iron pins that pass through the frisket joints and connect it

with the tympan. They are made to slip in and out of the joints

easily with the fingers, and are put in from the inside of the

joints, so that the heads are opposite to each other. It is a common

practice with pressmen, when they have occasion to take off the

frisket, to lay the pins on the form. This ought never to be done;

for I have known an impression pulled under these circumstances,

at a good wooden press, without the frisket, and where the pins

were forgot. The consequence was, the destruction of types, and

the bedding in of the pins into the platen:--there was loss of

types--loss of time in replacing them--the platen to be taken off

and planed, with the expense of doing it, in addition to which it

was reduced in thickness full a quarter of an inch, and the further

loss of time while it was doing and hanging again, and justifying the

head. They may always be safely laid within the chase between the

quoins, where they can do no harm, and cannot roll off.

FRISKET STAY.

A slight piece of wood, generally fastened to the ceiling of the

press room, and hanging down to the fore end of each press, for the

frisket to rest against when it is turned up.

FROZE OUT.

In winter when the paper is froze, and the letter froze, so as

the workmen cannot work, they say, _they are froze out_.--_M._

In consequence of greater care in warming printing offices in

winter than in the time of Moxon, the workmen are not now “froze

out;” for there would be no excuse admitted for the non-execution

of parliamentary work, newspapers, reviews, magazines, and other

periodical works.

FRY, EDMUND.

A celebrated type founder, whose foundery was rich in Oriental and

other types for foreign languages, the forms of the characters of

which varied from the Roman character. Dr. Fry sold the whole of

his foundery to Messrs. Thorowgood and Besley, and which is now

incorporated with their previously extensive variety of types.

FUDGE.

To execute work without the proper materials, and where the workman

is obliged to substitute one article for another, and by contrivance

make his work passable: when such cases occur, they show the skill

and ingenuity of the compositor or pressman, in making his production

look well.

FULL CASE.

A case full of letters, wanting no sorts.

FULL FACED LETTER.

Types, in which the capitals, and the ascending letters of the lower

case, fill the whole square of the shank, so that the descending

letters project beyond the bottom of the shank. A full faced letter

is considerably larger in proportion than a letter of the regular

face upon the same body: they are convenient in jobs, as they produce

the effect of larger types, and take up less space.

FULL FORM,

or PAGE. A form or page with few or no breaks or white lines.--_M._

In a full form there are no short pages, nor blank pages.

FULL PAGE.

A page containing its full complement of lines.

FULL PRESS.

When two men work at the press, it is called a _Full Press_.--_M._

FURNITURE.

The term furniture includes all those pieces of wood that are used

in branching out pages, or jobs; in making margin for the folding of

books; and in locking up forms when they are imposed: it is generally

classed as reglet, furniture, side sticks, foot sticks, and quoins.

The height of it is five eighths of an inch, and ought to be the same

as that of quadrats; but the letter founders and the joiners vary

them both.

What is usually called furniture is in lengths of a yard each, and

commences with narrow, which is equal to a narrow quotation; broad,

which is equal to a broad quotation; double narrow; broad and narrow;

double broad; broad and double narrow; and narrow and double broad.

These are used for gutters, heads, and backs; to branch out large

jobs; to fill up with when a chase is too large, and to put round a

job when imposing, to keep the letter from the iron of the chase. The

bottom and two sides are flat, and the top has a groove planed in it

lengthways, the arc of a circle; this groove is said to be designed

for carrying the water off when the form is washed, but I cannot see

the utility of the groove for this purpose; its more obvious use is

to lower that part, so that the balls or rollers shall not touch

it in inking the form, which prevents the frisket tearing from its

pressure upon the inky furniture and from being continually lifted

up.

G.

GAELIC.

The Gaelic alphabet consists of eighteen letters: a, b, c, d, e, f,

g, h, i, l, m, n, o, p, r, s, t, u. Of these, five are vowels, a, e,

i, o, u; the rest consonants.--_Stewart’s Gaelic Grammar._ 8vo. 2d.

edit. 1812.

“It may be explanatory to mention, that the syllable _Kil_ is

supposed to mark the residence (the _Cella_), in ancient times of an

ecclesiastical recluse; and that _Kin_, _Ken_ (_Cean_) means head.

_Ken_-loch-Spelvie, &c. the Head of Loch Spelvie, &c. The letter

_C_ is always pronounced _K_ in Welsh and Gaelic”--_Sixth Report of

Commissioners for Building Churches in the Highlands of Scotland.

Appendix_, 1831. Note.

GALLEY.

Pieces of thin boards of different sizes, with ledges about three

fifth parts of the height of the letter on one end and one side, for

the types to rest against; others are made with a slice to slide

out, and keep a large page on without disturbing it, the coffin

having several slices fitted to it.--_M._ The use of the galley is to

receive the matter as it is composed, and to afford a level on which

to make up the pages.

Galleys are made of different sizes to suit the different works on

which a compositor may be employed; if it be a reprint, page for

page, he avoids encumbering his cases with large galleys, but takes

one that will hold a page comfortably, completes his page, ties it

up, and slips it upon a page paper, and thus proceeds; but if the

work be not a mere reprint, and is done in a companionship, then,

as each compositor must be setting at random, the work will require

different sorts of galleys, which must contain more matter; in the

latter case he will take one of the proper width for the page, but

that will contain two pages or more, in length, or one double that

width with a ledge down the middle, so as to hold two pages in width.

For works in quarto or folio he must have galleys of a greater width,

so as to enable him to have a quantity of matter at random till he

gets the making up; in doing this, where the page is in folio and

large, it is safer to make up on a slice galley, when he draws the

slice out with the page on it and places it under his frame, and thus

proceeds till he has made up a sheet, when he slides his pages off

the slice upon the stone to impose them; he must in this case have

four slices at least. The following is a representation of a slice

galley:

[Illustration: A slice galley]

For newspaper work brass galleys are employed, the bottoms thin,

and the ledges of brass which are on both sides and one end, while

the other end has a moveable ledge which fits into mortises in the

sides; by this means the compositor is enabled, when a galley full is

composed, to put a sidestick and footstick to it and quoin it, and

pull a proof in the galley.

Galleys are generally made of mahogany: those made of the old panels

of coaches are held to be the best, as the wood, being well seasoned,

is less apt to split or bend, and keeping their flat level surface is

requisite.
