174 THE MICROSCOPE. Nov. 



cent, albuminoids, four per cent, and mineral matter, one 

 half per cent. This all sounds well enoug-h, and would lead 

 the unwary reader to think that ice-cream was all rig-ht, 

 but the denouement comes in the results of microscopical 

 research. The microscope shows the presence, in London 

 ice-cream at least, of bedbug's, bugs, legs, of fleas, straw, 

 hair, coal, dust, woolen and linen fiber, tobacco, epithelial 

 scales, and muscular tissue. Even the microscopical ex- 

 amination, however, is delectable compared with the re- 

 sults of bacteriological studies. These reveal in street- 

 barrow ice-cream a maximum number of seven million mi- 

 crobes per cubic centimeter, while the shops haveonly one 

 million per cubic centimeter. The character of the micro- 

 organisms is extremely mixed. There are are the bacteria 

 coli communis, besides spirilla.^ and putrefactive microbes 

 of various kinds. We find no account of a chemical analy- 

 sis, which would perhaps add the final touch to the patho- 

 logical picture of the ice-cream of the shops." — Boston Med-
