planted at the same time without exposure to the sporidia of the 

 fungus presented no unhealthy appearance. 



Mr. Quekett argues that all the grains of rye subjected during 

 germination to the influence of the sporidia of the fungus in both 

 sets of experiments having produced plants infected with ergot, 

 while the plants derived from grains not so subjected escaped disease, 

 a convincing proof is aff"orded that their infection could not have been 

 the effect of chance, but must have resulted from the artificial intro- 

 duction of the sporidia ; and that the infection of the rye only, while 

 the wheat and barley escaped, is to be attributed to the greater sus- 

 ceptibility of the rye to infection, as proved by the much greater fre- 

 quency of the production of ergots in that species of grain.
