In this article the chemical analyses of two of the proteins of the bovine lens are described. The analyses of these proteins will probably be similar to those of the proteins of the human lens. Until more chemical information of the normal lens protein is available, it will be difficult to interpret the chemistry of the cataractous lens. The problems of the formation of the cataractous lens are many, and the amount of material is small.
The investigation of the lens protein was begun in 1830 by Berzelius,1 who called the protein of the lens, crystallin or globulin. Later, Mulder,2 Rüling,3 Lieberkühn,4 Vintschgau,5 Béchamp,6 Laptschinsky7 and Cahn8 studied the lens protein without adding any information that may be used at the present time. Mörner9 was the first to analyze the proteins systematically. Jess10 followed Mörner with more detailed investigation of
