18, the degree of Doctor of Philosophy was conferred upon 
W. W. Bonns, with a thesis on “Etherization of Tissues and 
Its Effect on Enzyme Activity”; and on C. W. Dodge, with 
a thesis, “Tyrosin in the Fungi: Its Chemistry and Methods 
for Its Study.” 
Publications and Papers——In the following list are in- 
cluded the titles of all papers published during the year by 
members of the staff and graduate students as a result of in- 
vestigations and observations made in the laboratories, 
library, herbaria, and garden. No small part of the inves- 
tigations completed remain unpublished, due in part to the 
large amount of time which has been devoted to other duties 
arising as a result of war-time conditions.
