There exists a striking identity in the composition of buck 

 wheat and rye. In the seeds of the former there is 27 per 

 cent, of husk. The 73 per cent, of flour, closely resembling 

 that of rye in color and properties, contains 10^ of gluten, and 

 52 of ordinary starch. The greatest resemblance also exists in 

 the constitution of the ash when both plants have been grown 

 on the same soil. The dried grain of rye contained 2.4 per 

 cent, that of buckwheat 2.1 per cent, of ash.
