THE MICROSCOPE. 



but the cells of the muscular substance remained 

 perfectly colourless. The author concludes, therefore, 

 that Bismarck brown possesses the property of colouring

Mr. Collins has introduced a very complete Mounting- 

 Case, which will prove useful to microscopists, especially 

 so to those who devote a good deal of attention to the 

 preparation of specimens. A place is here found for 

 everything: the little box contains: Shadbolt's turn- 

 table, brass table, spirit-lamp, pipettes, spring clips, 

 wooden clips, tweezers, tin cells, balsam, marine glue, 

 asphalte, turps, gold size, thin glass covers, glass slips, and 

 five extra bottles. The price of this neat and convenient 

 case is 30s. Another box, more particularly adapted for 

 anatomical purposes, includes a neat injecting apparatus.
