 silcht., 2 {1914), No. 2, pp. 101-151, figs. 4). — This article describes a method of 

 distinguishing varieties of plants that involves a precipitin reaction (E. S. R., 

 29. p. 144) in which the serum of rabbits is used in connection with a liquid 

 prepared from the meal of the grain to be tested and sodium chlorid (1: 10). 



Results obtained with varieties of peas, clovers, oats, and wheat, which were 

 not altogether conclusive, are given.
