clusions reached by Miiller. He follows these statements by 
similar tables made during a series of years in different localities; 
he also gives the results obtained by McLeod in Ghent and by 
Lindmann in other northern regions. 
As all of these results point in the same direction, except in 
certain instances which admit of a reasonable explanation, he 
says the mutual dependence of these plants and animals can best 
be expressed as follows: Those insects and flowers which theo- 
retically may be considered as influencing each other in respect 
to their mutual adaptation to this method of fertilization are those 
which in reality do influence each other the most strongly. 
This expression, he says, is the same as that stated by Miller, 
though in somewhat different terms, and adds, that it has not yet 
been confirmed by actual statistics, but when this has been done 
a very important biological law will have been discovered, and 
one which will serve to make clear other points now in obscurity. 
His work in the botanical garden of Berlin was undertaken to 
prove that Miiller’s general methods were trustworthy, but 
he prefers another method of classification of flowers and flower- 
fertilizing insects, and for this reason he purposely selected a lim- 
ited territory for his field of observation, as in this way the worth 
of his classification would best be made evident. 
In order to see how his particular method applied to larger 
stretches of country, other observations were made at different 
intervals, in various localities and the results arranged in a similar 
manner; finally he states that the comparison of all the observa- 
tions so far made, lead to the probability of the truth of Miiller’s 
conclusion, and that further work in this same manner is neces- 
sary to establish this conclusion as a fact.

Uredo Viale, a new fungus destructive to Grape Vines, was 
found on the leaves of a Vitis near a country house between Kings- 
ton and Rockfort on the Island of Jamaica and is named in honor 
of M. Pierre Viala of the sip ear School of Agriculture at —
