New York Botanical Garden Museum. Twenty-nine members and 

 friends were present. 



The minutes of the preceding meeting were accepted as read. 



The first part of the scientific program was presented by Mrs. 

 Annette Hervey who spoke on "The Use of Phycomyces Blakes- 

 leeanus in the Assay of Thiamin in Agar." The talk was illustrated 

 with slides. 



The second portion of the program was presented by Mr. 

 John D. Dodd who gave an illustrated talk on "Three Dimensional 

 Cell Shape in the Carpel Vesicles of Citrus Grandis." The speak- 

 er's abstract follows : 



Internal cells from the carpel vesicles (juice sacs) of grapefruit were 

 examined in the living condition. Cell walls were stained lightly with neutral 

 red. Records were kept by making a careful drawing of each cell. In order 

 to insure completely impartial selection, the data were not tabulated and 

 summarized until 100 cells had been drawn. Results showed an average of 

 13.85 faces per cell. The range in number of faces was from 9 to 18. 

 The largest number of any one type was 22 cells each with 14 faces. Of 

 the rest 39 cells had more than 14 faces and 39 had less. The number of 

 edges per face varied from 3 to 8; 0.8% were triangular, 25.9% were 

 quadrilateral; 41.6% were pentagonal; 23.6% were hexagonal; 7.0% were 

 heptagonal and 1.1% were octagonal. 



The meeting was adjourned at 4:30 p.m. and was followed by 

 tea which was served by friends at the Garden. 

 Respectfully submitted.
