 Roswell L. Colt, Esq. : 



Dear Sir — At your request, made through our mutual friend, 

 Mr. D. Jay Browne, I have made analysis of Indian corn, aud of 

 the corn cob, which I have now the honor of communicating to 

 you. 



The variety operated upon was a very prolific one, produced 

 by mixture of the " Red cap" and " Canada'' corns, and was 

 grown upon the farm of Mr. Thomas Andi-ews, in Smithfield, 

 Rhode Island. There were generally four or five ears of corn 

 on each stalk, the average being four ears. 



To determine the relation of the corn to the cobs, I shelled, 

 counted, and weighed the grains or kernels, and weighed also 

 the cobs. 



The corn is an eight-rowed variety. 



First sample of the lot : 



The cob weighed, .' 260 grains. 



The corn weighed, 1 . 970 grains. 



Number of kernels on the ear, 332 kernels. 



Increase from one kernel, 1 . 328 kernels. 



Second sample : 



The cob weighed, 280 grains. 



The corn weighed, 2 . 070 grains. 



Number of kernels, 325 kernels. 



Increase from one kernel, 1 . 300 kernels. 



One hundred grains weight of this corn, on analysis, yielded to 

 ether 4.75 grains of fat fixed oil, and to alcohol 4.11 grains of 

 zeine and sugar. (Zeine is the peculiar gluten of Indian corn.)
