that it never produces the deleterious effects sometimes occasioned by 

 the latter. 



The same writer asserts th^t Ergot of Oat is sometimes collected and 

 sold either per se, or mixed with that of rye. It differs from the latter 

 m the ergots being considerably more slender. 



Ergot of the North African grass Arundo Avipelodesmos CiriUo^ 

 known as Diss, has been collected for use, and according to Lalloinaut* 

 is twice as active as that of rye. It is from 1 to 3 inches long by only 

 about y^-^ of an inch broad, generally arched, or in the large ergots twisted 

 spirally. We find it to share the structural character of the ergot of 

 lye;^ it is in all probability the same formation, j-et remarkably 



modified.
