360 MARINE BIOLOGICAL LABORATORY. 



eminently well to render, and we can now face the growing 

 complexities of the Laboratory with confidence and more ease. 



Among additions to the equipment of the Laboratory during 

 the year may be noted a large motor boat, a Zeiss microscope 

 of the best and newest model and a new microtome. The mess 

 did an unusually large business and exhibits an unexpectedly 

 large surplus, all of which is to be turned back into improve- 

 ments in its equipment and service. Among these may be 

 mentioned a new ice-house costing $600.00 and a work-shop 

 costing ^250.00 already completed. The supply department 

 has made its usual gain in business transacted, and it is worth 

 noting that under Mr. Gray's management this business has 

 increased from $5,616.54 in 1906 to $10,303.61 in 1911. 



Our thanks are again due Mr. Crane for the donations which 

 have enabled us to maintain the work of the Laboratory on an 

 efficient basis; and for the presentation of additional stock of 

 the Yacht Club, and the Kidder Annex property. 



There are appended as parts of this report the names of the 

 staff for 1911, a list of investigators and students with a tabular 

 view of attendance since 1908, and lists of subscribing institu- 

 tions, of the evening lectures for 1911, and of the members of 

 the corporation.
