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 which 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 

 parallel 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 4ris 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 of 

 black enamel, as before mentioned. When this is melted and 

 incrusted in the iris, both are covered with glass, and heated
