METHOD OF MAKING ENAMEL EYES FOR ANIMALS, 121 
The instruments necessary fur making these are an enamel- 
' ler’s table, bellows, lamp, round pincers about six inches in 
length, which are closed by means of a ring, and with which | 
is held the iron-wire forming the support, and the base of these 
eyes, which it is impossible to blow. Procure another flat pair | 
of pincers of the same length, which are used for handling || 
the enamel, as also for stirring up the lamp. These instru- 
ments can be had ready made in every hardware shop. 
The materials from which the eyes themselves are formed 
_ is an assortment of cylinders of enamel of all colours, which 
can be purchased; besides some fragments or clippings of | 
mirror-glass, which are melted in the lamp into a kind of cy- | 
linder like the enamel, so that they may be ready for use when | 
required. During the process of melting these pieces of glass, 
considerable attention is necessary to free them from spots and | 
globules of air. These cylinders can be procured ready made 
in the shops ; and at various glass-manufactories. 
The table is placed ina situation where the light of day | 
cannot reach it, as the double light would distract the vision | 
during the operation. 
After the lamp has been lighted, the pipe of the bellows is 
directed towards the middle of the wick, which is slightly 
scattered in that part so as to procure a clear light-bluish flame, 
which is necessary to secure success in the operation, because 
if it is not clear, the colours of the enamel are liable to change 
during the operation of making the eyes. The enamel which 
we wish to melt should be applied to the extremity of the 
jet of the flame, which it will not burn, and often melts more 
easily than in the centre. 
As small eyes are less difficult than large ones, it will be | 
advisable to commence with them until we shall have acquired | 
practice. For small eyes, a small iron-wire is used about an 
inch and a half long, one end of which is held in the round 
pincers, and the other is approached to the fire, to which is 
exposed at the same time the enamel of the colour we wish | 
the eye, whilst the other is turned between the fingers until it | 
begins to melt. The quantity necessary for the size of the eye | 
is then fastened to the end of the iron-wire. This by being 
_ turned in the flame forms a small globe, and when it is suffi- 
ciently rounded, a little speck of black enamel is placed in the
