rice was to be ascribed to its small content of cellulose, or to its 
deficiency of vitamins. The first seemed to be the case, as starch- 
rich faeces again resulted from a mixture of ground polished rice 
and an antineuritic extract of rice-polishings. If the ground rice 
was mixed with washed rice-polishings, saw-dust, or ground filter- 
paper, the digestion was, on the other hand, very satisfactory, the 
faeces, just as in a simple diet of raw undermilled rice, being then 
mostly a white mass or a mass coloured pale green by bile, which, 
however, appeared to consist for the greater part of paper-fibres. 
We now tabulate the results of these experiments:

Thongh the admixture of cellulose seemed to have acted favourably 
with respect to the loss of weight, this did not retard the outbreak 
of the disease, it rather accelerated it. This again favours the view that 
polyneuritis gallinarum is not a consequence of general inanition. 
SUMMARY. 
1. Dur experiments lend sapport to CHAMBERLAIN, BLOOMBERGH and 
KILBoURNE’s experience that general deprivation of food may farther 
a development of polyneuritis. The outbreak of the disease is then 
quickened by abundantly drenching the organism with water. 
Starvation-polyneuritis, just as feeding-polyneuritis is engendered 
through a deficiency of “antineuritic’” substances, or so-called vita- 
mins. An addition of the latter exerts a curative effect upon either. 
2. Etiologically there is in feeding-polyneuritis no direct relation 
with the inanition that often attends it, in such a sense that the 
former should result from the latter. In one sense, indeed, the 
reverse is the case. Loss of body-weight may occur from the begin- 
ning of the experiment with a one-sided diet; however it occurs con- 
stantly only towards the outbreak of the disease (in consequence of 
a motorial disturbance in the digestion) and may even be preceded 
by an increase of bodyweight in spite of the one-sidedness of the diet. 
It is doubtful, whether a favourable effect on the condition of
