 [Some hints on mounting objects.] Ibid., VII. (1885) pp. 77-8 (1 fig.) 



Stowell, C. II. — Dissecting Insects. 



[The plan adopted by the author for holding the insects is as follows : — 

 An empty blacking box is filled to a depth of about 1/8 in. with melted 

 beeswax, and while this is still in a liquid condition, a grasshopper is 

 placed in it in the desired condition, and the whole left to cool ; when 

 hard, water is poured in and the dissection begun. When one specimen is 

 used up, the wax is again melted and anotiier insect inserted.]

 Thcrston, E. — Staining Bacteria for Micro-photographic purposes. 



[Explains the process with vesuvine and Bismarck brown, both in the case 

 of free bacteria and those occurring in the tissues. " The best form of 

 balsam for mounting bacteria is that which is dissolved in xylol, which 

 is very easy to work with and does not abstract the dye."]
