infected Sputum rieh in proteins, and the possibility of protein 

 rests due to deficient motility. In ulcer, a marked initial rise in the 

 protein content was noted, which was out of proportion to the 

 amount of acid secreted. This requires further study. In cancer 

 the authors were able to confirm the increased protein content of 

 cancerous achyHas and to show in practically all cases marked in- 

 crease in protein concentration out of all proportion to the amount 

 of acid present. In Cancer, this rises steadily and is usually most 

 marked in the more advanced specimens. This disassociation be- 

 tween the acidity and protein curves, the authors consider most 

 important; it emphasi/:ed the steady rise in the protein content as 

 digestion progresses. The high protein content cannot be due to the 

 action of the secreted juice on the bread but must be a special elabo- 

 ration from cancerous tissue. The value of this reaction, namely 

 the disassociation in the protein and acidity curves, is of value in 

 direct proportion as the acidity is low and as the protein continues 

 to diverge. In inflammatory conditions, as contrasted with func- 

 tional States, the authors find a greater protein content in the former 

 and insist on the necessity of examining the entire digestive cycle 

 owing to the possibility of undue protein concentration at certain 

 periods.

 Newton Harvey. (Physiol. Lab., Princeton Univ.) Masses of 

 luminous bacteria were dried on glass wool in a vacuum over cal- 

 cium Chlorid and ground to a powder. The powder will phosphor- 

 esce if moistened with tap-water or sea-water. Since new colonies 

 of bacteria can usually be obtained from the powder, if planted on 

 a suitable culture medium, all the bacteria are evidently not killed 

 by drying, but most of them are. 



If the dry powder is extracted with boiling ether for 10 hr., it 

 phosphoresces as strongly as before, after the ether is removed and 

 the powder moistened. Ether-treated material may give occasional
