A HISTORY OF SCIENCE 



so much as an inkling taught that first class of students. 

 You will find it appalling, as you muse, to reflect upon 

 the amazing mixture of utter ignorance and false 

 knowledge which the learned professor of that day 

 brought to the class-room, and which the "educated" 

 student carried away along with his degree. The one 

 and the other knew Greek, Latin, and Bible history 

 and doctrine. Beyond that their minds were as the 

 minds of babes. Yet no doubt the student who went 

 out from the University of Jena in the year 1550 

 thought himself upon the pinnacles of learning. So he 

 was in his day and age, but could he come to life to-day, 

 in the full flush of his scholarship, yonder wood- vender, 

 plying her saw out here in front of the university build- 

 ing, would laugh in derision at his simplicity and ig- 

 norance. So it seems that, after all, the subjects of 

 John the Magnanimous have changed more than a 

 little during the three hundred and odd years that 

 John himself, done in bronze, has been standing out 

 there in the market-place. 



THE CAREER OF A ZOOLOGIST 



Had one time for it, there would be real interest in 

 noting the steps by which the mental change in ques- 

 tion has been brought about ; in particular to note the 

 share which the successive generations of Jena pro- 

 fessors have taken in the great upward struggle. But 

 we must not pause for that here. Our real concern, 

 despite the haunting reminiscences, is not with the 

 Jena of the past, but with the Jena of to-day ; not with 

 ghosts, but with the living personality who has made 

 the Jena of our generation one of the greatest centres
