'mind to prevail generally, it would become a question whether they should not be associated with the 

 ^poriferous fang], the vesicle l"-iiii_- regarded simply as a veil. I am myself inclined to this view, but at 

 nt think it savours t<.u much of theory to venture to propose it.

I am indebted to my valuable friend, tbe Rev. M. J. Berkeley, for the following 

 additions] remarks: — 



Attention has of late been frequently called to parasitic fungi, because of their real 

 or supposed connection with the diseases which have proved so disastrous to potatoes 

 and grapes. It is at least clear that these diseases are constantly attended by specific 

 fongi, which arc highly destructive, but it is very probable that the exciting cause has 

 been the introduction of foreign manures into general use, which have injured the 

 constitution of the subjects, and rendered them liable to any external attack. As in 

 the history of all diseases, and especially as regards infection and contagion, a 

 thousand anomalies occur on every side, but the notion above stated is the only one 

 which meets the generality of undoubted facts, and which does not clash with what 

 is clearly ascertained respecting the agency of fungi in these cases, for like Puccinia 

 grammii, both Botrytit ivfesfans and Oklium Tucberi are developed amongst living, 

 though possibly unhealthy tissues which are either immediately destroyed or 

 materially affected by their presence. No cure has been discovered for the potato
