 SoBBY, H. C. — Preparation of Transparent Sections of Kocks and. Minerals. 

 (^Tn part.) 



[Account of the method he originally adopted for rock sections when 

 " everything had to be learnt, and there were then none of the facilities 

 you have now."]

 Teasdale, W.— G. Chantrill's Method of keeping objects alive for many 

 months. 



[A number of zinc shelves kept under a bell-glass, the requisite supply 

 of moisture being provided by a quantity of thick felt kept constantly 

 saturated.]

 [SoEiking in potash for a day.]

 „ „ — Glycerine-Jelly Mounts. 



[Washing superfluous jelly oti' with a tooth-brush under water is a

 " VoLvox." — Microscopy. 



[Examining circulation of blood in a tadpole's tail. Take a hollow 

 slide, or make a little trough by cementing four little strips of glass 

 on a 3 X 1 slip so as to make a thallow cell. After placing the 

 tadpole on its side in the cell and covering with water, drop a very 

 small quantity of chloroform over its head. There is then " no pain 

 to the tadpole nor risk of bruising it as when it is put under pres- 

 sure, and should too much chloroform have been given it could not 

 die in an easier way."]

 White, T. C. — On the Injection of Specimens for Microscopic Examination. 

 [Describes the process of making transparent injections of a small 

 Mammal with cold injection fluid (Beale's blue fluid), mounting in 

 weak glycerine and camphor- water, and not in balsam or dammar, 

 which would show nothing bej'ond the injected vessels, all the sub- 

 structure which bears an intimate relation to the vascular arrange- 

 ment being obliterated. Criticism of Di-. Carpenter's recommendation 

 of injections by professional mounters.]
