intagliotype (in-tal'yo-tlp), . [< intaglio +

taglio on a metallic plate, resembling somewhat 
the graphotype process. The plate is first coated 
with zinc oxid rendered very uniform and smooth by hy- 
draulic pressure. Upon this surface the design is traced 
with an oily ink. The coating is then washed with a solu- 
tion of zinc chlorid, the effect of which upon the parts not 
protected by the ink is to harden them, leaving the parts 
under the ink-tracings in a friable condition. When these 
friable parts are removed by brushes or other implements, 
the design is left in intaglio. From the plate so prepared 
stereotype or electrotype plates are obtained for use in 
printing. Other solutions are sometimes substituted for 
the zinc chlorid.

integral 
An integral whole is that which has part out of part. 
Parts integral, because each is endued with his proper 
quantity, not only differ in themselves, but also in site, or 
at least order; so that one is not contained in another. 
For this it is to have part out of part. . . . This whole is 
termed mathematical, because quantity is of mathematical 
consideration : vulgarly, integral.

4. In math. : (a) Of, pertaining to, or being 
a whole number or undivided quantity, (b) 
Pertaining to or proceeding by integration: 
as, the integral method Integral calculus a 
branch of the infinitesimal or differential calculus, which 
is partly the inverse of the pure differential calculus in 
the narrower sense. The integral calculus is sometimes 
taken to include the solution of differential equations, 
and in that case a comprehensible definition of it can be 
given : namely, it is the complete discussion of differential 
equations. So considered, it has the theory of functions 
as an outgrowth. But the subject of differential equations 
is sometimes excluded from the integral calculus ; and 
then the latter is left without any clear unity, including 
the finding and discussion of integrals, a part of the theory 
of functions, the theory of spherical harmonics, the theory 
of residuation, etc. The integral calculus is distinguished 
irom the differential calculus in the narrow sense by the 
far greater importance in it of imaginaries. Compare cal- 
culus, 3. Integral curvature, function, etc. See the

3. In math., the result of integration, or the 
operation inverse to differentiation. An integral 
is either the integral of a quantity or the integral of an 
equation ; and the latter phrase has two senses, (a) The 
integral of a function is relative to an independent vari- 
able, and is taken between limits, which, however, may 
remain indefinite. A definite integral is conceived as 
resulting from the multiplication of each value of the 
function by the corresponding value of the differential of 
the independent variable, as this variable passes through 
a continuous series of values from one of the limits, 
called the first, lower, or inferior, to the other, called the 
second, upper, or superior, followed by the addition of 
all the infinitesimal products so obtained. Suppose, for 
example, that the value of a quantity y depends upon that 
of another quantity x, so that y = Fa-, where F signifies 
some operation performed on x; then, measuring off x 
and y, upon the axes of a system of two rectangular coor- 
dinates, we shall get a plane curve. (See the figure.) Let 
OX and O Y be the axes of x and y respectively. Let A be 
the point for which x = a, y = ; and B the point for 
which x = b, y = 0. Let P be the point for which x = a, 
while y=Fa; and v 
let Q be the point 
for which x b, 
while y=Sb. Then 
conceive the whole 
space APQB to be 
filled up with lines 
parallel to the axis 
of Y, p.t infinitesi- 
mal distances from 
one another. Then 
y.Ax will measure 
the infinitesimal 
area between two 
of these lines, the 
Integral. 
OX is the axis of X, OY of Y. The area 
APQB equals y* y.Ax. 
axis of abscissas and the curve; and the sum of all such 
infinitesimals, or the integral of y relatively to x from x=a 
ft 
tox = b, written / ydx, will measure the whole area 
J a 
APQB. It is to be understood that we never pass from 
one limit to the other through infinity ; but if the first 
limit is greater than the second, the sign of the definite 
integral is reversed. This gives a distinct idea of a definite 
integral, in case the variable is real. If the variable is 
imaginary, the definite integral is still conceived as the 
sum of all the values of yAx from one limit to the other; 
only there is in this case an infinite variety of different 
paths by which the variable can pass from one limit to 
the other. It is found, however, that in the plane of the 
imaginary variable there are generally certain points such 
that integration round one of them in a closed contour 
gives a constant value not zero, and but for that the path 
nf Integration dues not affect the result, for all ordinary 
functions. An indefinite integral is a function of the in- 
dependent variable with an arbitrary constant or wholly 
indeterminate; constant added to it, and such that if its 
value for one value of the independent variable is sub-
