Egg-Shells of Echidna and Other Vertebrates, by 

 R. Neumeister ( " Zeit. Biol.," 1894, 31, 413-420). — The egg- 

 shells of Echidna aculeata (E. hystrix) consist of a keratin-like 

 substance containing 5 per cent, of sulphur. It is, however, 

 digested neither by gastric nor by pancreatic juice. Some other 

 keratins are similarly resistant. In invertebrates the organic 

 basis of egg-shells is chitin or some other skeletin. Keratin 

 appears to be only present in the egg-shells and membranes of 

 vertebrate animals. In the frog only has mucin been described. 

 The eggs of some birds and reptiles are briefly referred to in 

 this connection. Calcium carbonate is the principal inorganic 

 constituent. — Jour Chem. Socy. Ahs., 1895, Ixviii., 54.
