BIOLOGICAL AND MICEOSCOPIOAL DEPAETMENT 



ACADEMY OF NATURAL SCIENCES. 



On the evening of March 28th, 1868, a meeting of gentlemen 

 interested in the organization of a Microscopical Society was held 

 at the office of Dr. James Tyson, at which sixteen were present, 

 while written or verbal communications signifying sympathy with 

 the project were presented from at least as many more. 



Dr. R. S. Kenderdine was called upon to preside and Dr. Tyson 

 to act as Secretary. A letter from Prof Jos. Leidy was read, urging 

 the advantages of working under the Biological Department of the 

 Academy of Natural Sciences. Such, or a similar plan of organi- 

 zation met with approval, and a committee, consisting of Drs. H. C. 

 AVood, Jos. Leidy, Wm. Pepper, J. H. McQuillen and James 

 Tyson, was appointed to take into consideration the propriety and 

 feasibility of forming a Microscopical Department of the Academy 

 of Natural Sciences, and to report at a meeting to be held Saturday 

 evening, April 4th, at the same place. 



Ajyril 4th, 1868. 

 President, R. S. Kenderdine, M. D., in the Chair. 



Seventeen gentlemen present. 



The Committee appointed at the last meeting reported, "It hav- 

 ing been strongly urged by members of the Committee and in- 

 fluential members of the Academy of Natural Sciences, that we 

 should not organize a purely Microscopical Department, we con- 

 sider that the objects of the meeting will be most successfully at- 

 tained by forming a Department or Section to be known as The 

 Biological and Microscopical Department of the Academy of Nat- 

 ural Sciences of Philadelphia, which will combine the objects of the 

 existing Biological Department and a Microscopical Society, in a 

 manner to be determined in accordance with Chap. XIII of the By- 

 Laws of the Academy, On the Creation and Government of Depart- 

 ments." 



This report was adopted and the Committee continued to carry 

 out its report.
