Minot, Charles S., Harvard Medical School, Boston, Massachusetts. Study of 

 nuclei oj cells in various vertebrates and other investigations in cytomorphosis. 



Dr. Minot died in November 1914, shortly after inaugurating inves- 

 tigations under the auspices of the Institution. His associate in research, 

 Dr. A. S. Begg, was authorized, however, to continue investigations 

 throughout the year for which the grant to Dr. Minot was made, and 

 Dr. Begg's report upon such work is as follows : 



Material was collected for the study of the relations of cell size and 

 nuclear size, but this study was discontinued at Professor Minot's 

 suggestion on account of his illness. The study of the abnormal 

 arrangement of cardinal and portal venous systems in a 12 mm. pig 

 embryo, with wax reconstruction, was completed, and also a model of 

 corresponding veins in a normal pig embryo of like size. This was 

 reported at the St. Louis meeting of the American Association of Anato- 

 mists, December 1914, and an abstract of the report was printed in the 

 Anatomical Record (vol. 9, No. 1, page 56, January 20, 1915). A 

 study was made of anomaUes in the same region in man and other 

 animals as reported in Uterature since 1670, involving approximately 

 200 articles and 250 cases. The completed paper covering the above, 

 with illustrations, will appear shortly in one of the anatomical journals. 

 A useful piece of laboratory apparatus was designed and was described 

 as "A simplified form of drawing apparatus" in the Anatomical Record 

 for September 1915. 



A study of intestinal epitheUum was begun and the material col- 

 lected. It is hoped that this studj'^ will be carried sufficiently far for 

 a report during the coming year.
