In the spring theygerminate on the decaying material, produce threads,and these threads carry (not corn-mildew spores, but)Berberry-blight spores. Such of these spores, then, asalight on the Berberry leaf pierce the cuticle at once,enter the flesh, and produce the flasks of the /Ecidiuminside: the flasks speedily push their mouths throughthe cuticle, the spores get blown away, and thosewhich happen to fall on corn blight it with grounds such as these, it is assumed that the.

On to what plants then are the spores of theGooseberry .Fcidium carried, so that it may talceanother and more permanent form, at length pass thewinter unscathed, and attack the Gooseberries nextsummer? No one knows. There is a slight gleamof new light in this paper, in the fact of the .-Ecidiummycelium of the Gooseberry being capable, undercertain conditions, of producing Uredo-like spores,and this fact strongly points to the possibility of someUredo and Puccinia being the ultimate condition ofthe ^-Ecidium. We are in the dark to the same extent with manyspecies of Puccinia. Is the Hollyhock disease at onestage of its growth an .Ecidium upon some totallydifferent plant? This is possible, but no one knowsfor cert
