Minutes of the Meeting of January 19, 1944 



The meeting was called to order at The New York Botanical Garden by the 

 President, Dr. Levine. There were 22 members and guests present. The min- 

 utes of the annual meeting of January 4, 1944, were accepted as read. Dr. Le- 

 vine appointed an auditing committee consisting of Dr. Dodge, Chairman, Dr. 

 Seaver, and Mr. Montagne. Mrs. Karling, the new Treasurer, was invited to 

 attend the meetings of the committee. It was moved by Dr. Robbins and voted 

 by the Club that the following communication sent by Dr. Graves concerning 

 Dr. Herbert M. Denslow be spread upon the minutes : 



Dr. Herbert M. Denslow, the oldest living member of the Club, who will be 92 years 

 old this coming August, a former President of the Club and Editor of the Bulletin, sends 

 his greetings to the Club and regrets that he cannot be present at the Annual Dinner. He 

 wishes the Club members a Happy New Year and assures them that he is comfortable and 

 being well cared for. 



The scientific program consisted of an illustrated lecture by Dr. Robert 

 Bloch of Yale University on "New Experiments on Cellular Differentiation 

 and Histological Pattern." The speaker's abstract follows : 



Various types of regeneration of histological pattern were studied in Monstera deliciosa, 

 Coleus hybridus, and Taraxacum kok-saghys. The study of cellular differentiation and his- 

 tological pattern in plants by means of regeneration experiments in more or less mature, 

 differentiated zones has various advantages. Compared with the fully embryonic apical 

 growing points, cells are here large, vacuolate and more thick-walled, and thus the changes 

 both in cytoplasm and membranes can be much better observed.
