centre, for the purpose of imitating the pupil. It is again ex- 
posed to the flame that the pupil may be blended into the mass. 
When it is properly incrusted, some glass is put upon it, which 
should extend three quarters across the hemisphere of the eye. 
This glass is intended to represent the vitreous humour of the 
eye, and from which all its brilliancy proceeds. The eye is 
still exposed to the flame until the glass has extended over 
that part of the eye which is intended for the iris; when we 
effect this, it is allowed to cool slowly. This kind of eye is 
made by joining several pieces of iron-wire together, which 
renders it easier to make them all uniform in point of size, 
because the first being close to our eyes guides us in the form- 
ation of the others. 
SECOND METHOD OF MAKING EYES. 
Another method of making eyes is the following :—Some 
pieces of iron-wire, from three to four inches long, are pre- 
pared, which have been well burned. Their strength must be 
proportioned to the size of the eye which is intended to be 
made. ‘These are curved in the middle over a tube of glass 
enamel, or any other cylindrical and polished body: the ex- 
tremities of each wire are united by twisting one over the 
| other, so that they perfectly fit the substance which they em- 
brace. It is this circle formed by the wire whieh makes the 
diameter of the eye, and the wire thus prepared is in the 
form of a rocket. The handle of this rocket is fixed into the 
round pincers, and the head of it curved by making it 
paral\el to that of the pincers. This circle is filled with com~ 
mon enamel, of the colour which we wish, extending it from 
the circumference to the centre, and when it is nearly the thick- 
ness of the wire, it is pressed while yet in a state of fusion with 
the flat pincers, so that it may extend equally over the entire 
circumference. It is then put into the fire to consolidate 
it. This having been done, the iris is formed by a drop of 
enamel of the proper colour. This is heated and pressed as 
before with the flat pincers, and when it is incorporated with 
the first enamel, the pupil is represented with a small speck oi 
black enamel, as before mentioned. When this is melted and 
inciusted in the iris, both are covered with glass, and heated |
