ARRANGEMENT OP APPARATUS, ETC. 



CHAPTER VI. 



Arrangement of Apparatus, Etc. 



Most methods adopted in these pages are taken 

 from the works of others, at least the principle is 

 the same although the arrangements are slightly 

 modified. Our claim is simply to have shown the 

 possibility of obtaining results with an ordinary 

 parafin lamp, equal if not superior to those hitherto 

 obtained with sunlight ; thus placing Micro-photo- 

 graphy within the power of all. 



It would be an impertinence as well as an injus- 

 tice to those from whom we have learned much, 

 if no mention was made of their work in these 

 pages. We have no intention of attempting a 

 classification on the ground of superiority or priority 

 but will mention what we know, in the order it 

 happens to present itself. 



All microscopists are acquainted with the beauti- 

 ful photographs of N. Ehomboides, published by 

 Mr. Woodward in the Journal of the Microscopical 

 Society. The arrangement he adopted was very 

 similar to that employed with the eight immersion 

 by us, and with which the photograph of S. Gemma 

 was taken. He seems to have always used sunlight 

 and the wet process, which as a rule give results far 

 superior to those obtained by lamplight and dry 

 plates.
