928 SUMMARY OF CURRENT RESEARCHES, EIC. 



Technical Notes, various. — 



Siliceous Cement, for protecting corks from the fumes of acid, &c. — Mis equal 

 parts colloid silica and thick gum-water, with sufficient gilders' whiting to 

 make it of the consistency of treacle. — Labelling slides. 



Carbolic Acid Preservative, for animal and vegetable tissues. — Carbolic acid, 

 1 drachm ; alcohol, 2 drachms ; distilled water, 12 oz. : dissolve the carbolic 

 acid with the alcohol, then add it to the water and boil for ten minutes. 



Acetate of Aluminium. — To 1 part acetate add 4 parts distilled water. This 

 is very good for preserving vegetable colours, as in desmids and other 

 algae. 



Glycerin and Acetic Acid is useful for mounting minute insects, &c. ; glycerin, 



1 oz. ; acetic acid, | oz. 



Dammar Cement. — Dissolve gum dammar in benzole, and add one-third gold- 

 size ; it dries very quickly, and is preferably used as a first coat for fixing 

 the cover-glass when glycerin is used for mounting. 



Gum, for attaching labels, covering papers, and objects mounted dry. Dissolve 



2 oz. of gum arable in 2 oz. of water, and add 2 drachms of soaked gelatin, 

 30 drops of glycerin, and a lump of camphor.
