In conni>ction with the question of testing for sulphites in foods, samples of 

 ;,'reen sweet corn, raw and cooked in different ways, were distilled with dilute 

 phosphoric acid. *' The distillate was o.xidized by bromin water and tested for 

 sulphuric acid with barium chlorid in the usual way." In every case a precipi- 

 tate was obtainetl. showing that some sulphur compound is cleaved from the 

 fresh corn under the experimental conditions. The evolution of sulphur from 

 \egetable substances was still further tested with fresh sweet potatoes, tomatoes, 

 cucumbers, cabbage, string beans, peas, celery, and onions, and sulphur was 

 found in the distillate in all cases except with cucumbers and peas.

On the assimilation of protein introduced parenterally, W. Cramer iJoiir. 

 I'til/xiol., 37 (1908), A'o. 2, pp. t'i6-157). — The results obtained in the investiga- 

 tions show, according to the author,, "that protein which has passed unchanged 

 through the intestinal wall can be assimilatwl and evidence is adduced to show 

 that this assimilation is brought about by the leucocytes ingesting the protein. 



"Tins Ic.'ids naturally t<i the (piestion whether such an assimilation of un- 

 dianged protein takes place at all after a meal and whether the mechanism of 

 the assimilation of the i)rotein of the food from the intestinal canal is similar 

 to the processes which regulate the assimilation of protein introduced into the 

 peritoneal cavity. 



"The fact that the mwhaidsm of the assimilation of protein from the peri- 

 toneal cavity works under the most favt)rable «-onditions- after a meal suggests 

 that unchanged protein is absorbinl and assimilatinl under normal conditions." 



From the ex|)erimental evidence presented it follows, according to the author, 

 that protein is "assimilate«l normally witliout being broken down in the in- 

 testine. Such a i»rocess takes place of course only to a limited extent and not
