The bulk of the data obtained was on starchy-sweet and yellow- 

 colorless ratios, and will be merely summarized at present: (1) the 

 ratios were virtually identical on both ears, and (2) any marked 

 deficiency of a given class on one ear always appeared in a strikingly

 interpreted. One feels, however, like regarding this as an isolated 

 exception. 



II. Purple-red ratios are also about as consistent as could be 

 expected (table III). Probably the only significant case is 682-680. 

 Although the converse has been well demonstrated for other
