As being the most likely of any to be susceptible to disease, 
it was decided to test in the first place these two Solanums. Pot 
experiments were therefore commenced this spring and a few 
results have already been obtained. Although the investigations 
are not complete, the results are of some importance and are 
worthy of record. It is hoped to publish next season a more 
detailed account. The experiments were as follows :— 
Solanum nigrum. Seeds were sown on May 18th in pots of 
infected soil obtained from Ormskirk, Lancashire. Four pots 
were sown and the seedlings, which appeared about June 15th, 
were thinned out to six plants per pot. One pot was examined 
on August 7th. Four plants out of five were found to possess 
swellings at the base of the stem, in each of which the sporangia 
of Wart Disease could be detected with a lens. Sections 
and extended over an area of 3 or 4 mm. Details as to their 
mode of origin and place of infection are reserved till a later 
paper. 
The remaining plants, some 18 in number, were not examined 
till September 13th, when no excrescences were present, DOr, 
with the exception of one plant, were any sporangia found. 
In two or three cases the base of the stems had been injured, 
and it is possible that the injured area may have represented 
a wounded surface left by a small wart formed by Synchytrium 
which had fallen off.
