positive results. Two of their fowls fed on gradually smaller quan- 
tities of unhusked rice, developed polyneuritis. Eight fowls, supplied 
with water only, not with food, presented three positive, two 
doubtful and three negative cases. 
The result, now, of our control-experiments was that out of eight 
fowls that had been given drinking-water only two died of typical 
inanition, the other six developed polyneuritis. There was no mista- 
king the symptoms, and the diagnosis could be substantiated by the 
examination of the nerves. We are not able to say why previously 
only negative results were obtained. CHAMBERLAIN c. s. attribute them 
to the circumstance that the symptoms manifest themselves only 
very short time before death and, at this juncture, escape our notice 
in consequence of the general weakness. I cannot enter in their view, 
first. of all because, in my previous cases no degenerative changes 
were found in the nerves. 
Moreover the weakness and emaciation, which occur frequently 
with a one-sided diet (emaciation being in this case even sometimes 
detected by CHAMBERLAIN c.s. in as high a degree as in starving 
animals) do not prevent the detection of pareses and paralyses. — 
The following table gives the results of our starvation and 
drenching experiments :

These figures seem to justify the conjecture that the drenching 
and especially the forced supply of an abundance of water in the 
crop has quickened the outbreak of the disease. However, it is 
difficult in this case to draw a positive conclusion from them,
