search and for the training of students in the several 
branches of applied biology. At first the Bussey Institution 
formed a part of the Graduate School of Applied Sciences, 
but a few years later the institution staff was made a sepa- 
rate faculty of the University and Professor Wheeler was ap- 
pointed its dean. He served in this capacity from 1915 to 
1929. He frequently spoke of this long stay at the Bussey 
as including the best years of his life. During that time he 
always had clustered about him some half a dozen graduate 
students working in entomology toward the degree of Doctor 
of Science, which was the applied science degree awarded by 
the University to students in applied biology. Most of these 
students now hold responsible positions in colleges, univer- 
sities or similar institutions in America and abroad, and 
their consistently high attainments show very clearly the 
deep influence exercised by his remarkable intellect upon 
their subsequent careers. 
In 1929 he resigned from the deanship and moved his work 
to Cambridge, pending the completion of the New Biological 
Laboratories. No new dean was appointed, as the several 
biological units of the University were soon to be consoli- 
dated and made a part of the Faculty of Arts and Sciences, 
with headquarters in the new building. There he spent his 
last years, continuing to teach until his retirement in 1934. 
After that he still retained his same quarters in the labora- 
tory, where he worked continuously until the last day of his 
life, even more actively than before, since the time previously 
devoted to lectures and students could be spent upon his own 
research. During this time his energy and enthusiasm never 
lagged and, as he told me only a few days before his death, 
he had already on hand collections of ants that would take 
him many years to work up. This, of course, did not take 
into account the many related biological problems that con- 
tinually arose in his mind in connection with taxonomic 
work. At that moment he was just finishing his last exten- 
sive manuscript dealing with mosaic anomalies in ants, an 
investigation which had unexpectedly developed from the 
study of some collections of ants recently received from the 
American tropics.
