conichalcite 
conica, Gr. KwfiKij TOJU^], a curve formed by the intersec- 
tion of a plane with a right circular cone. If the plane is 
more inclined to the axis of the cone than is the side of the 
cone (tig. 3), the intersection is oval and is called an eUijise. 
The circle is one limit of the ellipse that, namely, in which 
the plane becomes perpendicular to the axis of the cone. 
If the plane is less inclined to the axis of the cone than is 
the side of the cone, it will also cut the second sheet of 
priateness.

2. In math., a relation between three numbers 
such that the difference between two of them, 
which are said to be congruent, is divisible by 
the third, which is called the modulus. The 
following example shows the mode of writing a congru- 
ence : 
which means that any integer being substituted for x, the 
remainders of the quantities on the two sides of the sign = 
after division by 7 are equal. See congruency.

Conic Sections. 
The two principal forms are fig. 5, giving the hyperbola, and fig. 3, 
giving the ellipse. Fig. 4 is the intermediate case, giving the parabola. 
The degenerate form of the hyperbola is a pair of straight lines, as 
shown in fig. i. Fig. 2 shows the circle as a special case of the 
ellipse having no special relations to the infinitely distant part of the 
real plane, though it passes through two fixed imaginary points on the 
line at infinity. 
the cone on the other side of the vertex (fig. 5), and the 
twofold curve thus generated is a hyperbola. A particular 
case of the hyperbola, produced when the plane passes 
through the vertex of the cone, is that of two intersect- 
ing straight lines, called a degenerate conic. Intermedi- 
ate between the ellipse and the hyperbola is the case where 
the plane is parallel to the side of the cone (fig. 4), and 
the curve thus produced is a parabola. The degenerate 
form of the ellipse is a point, that of the parabola a 
straight line. The degenerate forms are not true conies, 
because they are of the first class, the conies being of the 
second class. Spherical conic section, a curve pro- 
duced by the intersection of a sphere with a cone.

Conical bearing. See tearing. Conical gearing. See 
gearing. Conical map-pro.) BCtion, the projection of the 
earth first upon a tangent or secant cone with the subse- 
quent development of the cone. The best-known conical 
projection is Konne's, used for the map of France. " In 
constructing a map on this projection, a central meridian 
and a central parallel are first assumed. A cone, tangent 
along the central parallel, is then assumed, and the cen- 
tral meridian developed along that generator of the cone 
which is tangent to it, and the cone is then developed on 
a tangent plane. The parallel falls into an arc of a circle 
with its center at the vertex, and the meridian becomes 
a graduated right line. Concentric circles are then con- 
ceived to be traced through points of this meridian at ele- 
mentary distances along its length. The zonespf the sphere 
lying between the parallels through these points are next 
conceived to be developed, each between its correspond- 
ing parallels. Thus all the parallel zones of the sphere are 
rolled out on a plane in their true relations to each other 
and to the central meridian, each having in projection the 
same width, length, and relation to the neighboring zones 
as on the spheroidal surface. As there are no openings 
between consecutive developed elements, the total area 
is unaltered by the development. Each meridian of the 
projection is so traced as to cut each parallel in the same 
point in which it intersected it on the sphere." Craig,
