Prof. Emily L. Gregory presented a paper on “ Theories of the 
Origin and Nature of the Starch Grain,” giving the history of the 
subject from the work of Naegeli to that of Meyer, who has re- 
cently submitted evidence that the substance of the starch grain 
is truly crystalline and not organized, so that all our theories of 
the growth of organized substance based upon the starch grain as 
a type fall, and we must begin to study the subject de ovo. 
The Secretary exhibited an ear of corn showing some perfect 
kernels of sugar corn distributed among those of yellow flint, as 
well as many kernels of an intermediate character. 
Mr. E. S. Miller remarked upon the blooming of certain Cac-
