THE DIRECTOR'S REPORT. 21 



versities and other laboratories. Indeed a large increase of 

 students is not to be desired, though we could well care for 

 some more. 



Treasurer's Report. The report of the treasurer again shows 

 an income sufficient for our expenditures, if not for our needs. 

 And again it will be seen that a very large proportion of income 

 is in the form of donations, for the major portion of which we 

 are indebted to the president of the board. Mr. Crane's sym- 

 pathetic and continual generosity puts us under a load of obliga- 

 tion which we can repay only by devotion of our time and best 

 endeavors to the interests of the laboratory. 



Our four main sources of income are : fees for tuition, rental 

 of rooms, sale of biological material and donations. The last is 

 the measure of our deficit, and it is to be questioned if the latter 

 can be reduced relative to the sources of income proper. There 

 is a continual tendency for increase. in expense of maintenance 

 due to higher salaries for the greater efficiency that comes of 

 long service, the increasing complexity of means of investigation 

 and the growing cost of everything. We can hardly expect a 

 great increase in tuition fees, though there should be some im- 

 provement there. But by our united endeavors we can surely 

 increase the number of subscriptions for rental of rooms. Many 

 rooms are now given free, a policy that has been of great service 

 both to individual investigators and to the Laboratory. It is not 

 proper, nor should we propose, to put the burden of room rents 

 on the shoulders of investigators, but institutions can and should 

 provide for the facilities used by members of their staffs. The 

 cash receipts of the supply department have increased from 

 $2,578.85 in 1900 to $5,616.54 in 1906, and $6,630.13 in 1908. 

 We are far from having reached the limit of possibilities in this 

 direction, and a steady growth is to be expected. 



Research Seminar and Evening Lectures. The research semi- 

 nar and evening lectures have been continued ; they have been 

 well attended, and their influence has been good. The physiology 

 lectures under Dr. Mathews' direction have been a great attrac- 

 tion; a large number of investigators have taken part and the 

 discussions have been lively and stimulating. 



Publication of the evening lectures ceased some years ago
