Cultures made from the diseased wood on gelatine, agar-agar, potato, 
etc., usually show at the expiration of from 2J to 48 hours numerous 
colonies of bacteria which are for the most part of one kind, namely, a 
Bacillus. 
As yet no inoculations have been made with the organism itself, but 
the disease has been produced in a number of cases by inoculations 
directly from diseased wood. Figure 2 shows the result of one of these 
inoculations, a being the point where the knife entered the tissue. The 
disease is one certainly worthy of careful investigation, as the losses in 
one establishment last year in this city amounted to over 50 per cent.

Our object in writing this preliminary note is to call the attention of 
florists and others directly interested in the matter to the work we now 
have under way and to obtain from them any information bearing on 
the subject they may consider of value. 
A disease which may be the same as the one here referred to has 
recently been reported from France by Messrs. Prillieux and Delacroix.* 
According to these writers Pelargonium and potato stems are affected 
with a malady which causes them to turn black and become rotten. 
The disease has been transferred from the potato to the Pelargonium 
and vice versa. A Bacillus , which the authors believe to be the cause 
of the trouble and which has received the provisional name of B. cauli- 
colous , Pr. and Del., has been found associated with the disease. No 
mention is made of the disease having been produced by inoculating 
with the organism, although it is claimed that this can readily be done 
bv direct inoculation.— B. T. Galloway. 
ADDITIONAL OBSERVATIONS ON ANTHRACNOSE OF THE HOLLYHOCK. 
Since the last issue (Yol. VI, No. 2) of the Journal of Mycology 
some additional facts have come to light concerning the Colletotrichium 
on the hollyhock.
