THE BRAIN OF DR. WILLIAM PEPPER.^'= 

 Died in California on July 28, 1898, and his body was injected with an embalming 

 fluid before its removal to Philadelphia. An examination of the thoracic and abdominal 

 viscera was made by Dr. A. E. Taylor in California. Dr. William G. Spiller of Phila- 

 delphia removed the brain in Dr. Pepper's home and found that the injection had not 

 been satisfactory for the brain was soft. The brain was placed in 10 per cent, formalin, 

 supported on cotton. In May, 1904, it was transferred to 95 per cent, alcohol. 



Immediately after its removal from the skull the brain weighed 1593 grams (Dr. 

 Spiller). The weight of the hardened encephahc parts in July, 1904, was as follows : 



Left hemicerebrum .......... 487 grams. 



Right hemicerebrum .......... 488 



Cerebellum, pons and oblongata. ....... 116 



Total 1091 



indicating a loss of 502 grams or 32 per cent, of the original weight. 



The brain is flattened and somewhat distorted. The cerebral peduncles were 

 nearly torn through and the separation was completed by a knife-cut. The cotton 

 placed at the sides of the cerebrum has pressed the temporal lobes together so as to 

 nearly hide from view all the basal parts of the thalamencephalon. The chief altera-
