It is worthy of note that Sir David Brewster, in his 
“ ^Natural Magic,” quotes the incantation scene from 
Cellini at length, and states his conviction that the 
appearances were brought about by optical apparatus, 
although he admits that little was known of the action of 
mirrors and lenses until the time of Kircher. 
It is obvious, however, that such primitive instruments 
were of the crudest kind, and can onlv be regarded as 
interesting curiosities. Up to within quite recent times 
lanterns for projection held about the same relation to the 
modem instrument as does the bone needle of the cave 
men to the sewing machine. Like most instruments of 
precision, the optical lantern is the outcome of many years 
of patient thought and labour, and is the result of the 
working of many minds. Xo individual can be credited 
with its invention or discovery. The crude idea is. as we 
have seen, to be found in Kircher’s book, and one improve-

ment has been suggested here, and another there, until we 
have before us a very perfect optical appliance. 
The gradual advance in the instrument very naturally 
follows the introduction of improved illuminants for more 
general purposes. The oil lamp was superseded by the 
argand gas-burner, and this was in its turn supplanted by 
the whiter and better light afforded bv mineral oil, while

before this, for the better kind of lanterns, Lieutenant 
Drummond s brilliant limelight was quickly adopted as the 
best for the purpose. This, too, may possibly, in the near 
future, give way to the still more brilliant electric arc
