 purposes, the impression of profitable intel- 

 lectual endeavor may be prematurely ac- 

 quired. There is much, however, to account 

 for the prevailing sensation of breathless 

 advance. The physiological and psycholog- 

 ical accompaniments of a breakneck pace 

 are not altogether lacking in the modern 

 world, and there are bacteriologists in 

 particular who will lend a credent ear to 

 affirmations of the rapidity of scientific 

 progress. However this may be, few can 

 question that the development of the sci- 

 ence of bacteriology has been marked by 

 an unusual tempo. To those who have fol- 

 lowed this development closely, discovery 

 has trod upon the heels of discovery in 

 bewildering succession. The scant thirty
