 <)J {I'.nts). No. .',:,(!. I. III). l.'>()0-h')06). — A new proteid was identified in e^rt: 

 yollv f(tr wbicb tiie name livetin is provisionally suggested. " Vitellin and this 

 new protein showed a very close similarity to one another, but they differ con- 

 siderably from ovalbunnn. and it may be concluded that this protein is anotber 

 idiistituent of egg yolk. It is suggested tbat tlie itrotein may be vitellin witbout 

 the pliospliorous-containing portion."

Identification of different plant proteids by means of specific sera, I). 

 (;.\sis illiitiii. Klin. Wclin.sclii:, '/J U'JOS), Xo. 7, pp. 3')S-,]l)0). — Proteids from 

 beans, lentils, peas, wheat, rye, barley, maize, beet .seed, and rice were studied 

 with bean, rye, rice, ami beef antisera. The results, according to the author, 

 show that plant jiroteids may be differentiated by the biological method when 

 the proper (piantitative relations are observed. The reaction is weaker or more 

 Iironounced jiccording to tlu' remote or near relationship of tbe different plant 

 ipfoteids used. In general, plant proteids are more readily dilTerentiated by 

 means of the i)recipitin re.-iction than are animal jtroteids. A bibliography is
