of my observations but I declined to be drawn into a controversy 

 since one brain badly hardened would hardly enable me to hold my 

 own against a man who has an unlimited supply of fresh brains, not 

 only of the adult animal but also of its foetus. 



However, my attentation has just been called to a statement by 

 Dr. Elliot Smith in the Anatomischer Anzeiger, Bd. XI, No. 6, p. 161 

 which seems to me to pass the bounds of scientific courtesy: 



"From Dr. A. Hill's account of the brain one would judge 

 that his material must have been in anything but a good state 

 of preservation. His wohle account is highly inaccurate and 

 misleading. For instance, speaking of the olfactory bulb, he 

 says: 'it is absolutely free from the cerebral hemisphere, the 

 rounded neck of the crus being crossed by the large an- 

 terior cerebral artery The bulb is cupped on its under 



surface.' It is hard to understand how he has distorted the 

 facts to fit in with this description, as every statement is abso- 

 lutely erroneous. Neither is the bulb free from the hemisphere, 

 nor is the cupping on the inferior, but on the upper part of the 

 lateral surface." 



"(The 'anterior cerebral artery' of Hill is a cerebral vein, 



which (in the absence of a superior longitudinal sinus) is very 



large and constitutes the main efferent channel for the blood 



of the cranial cavity.)" 



The photographs which I have sent to the Editor of the Anzeiger 



show with perfect clearness, unless they have "distorted the facts" 



that the bulb is absolutely free from the cerebral hemisphere, its 



isolation being accentuated by a large artery (whether or not the 



anterior cerebral I cannot now determine) which crosses the crus in 



company with a large vein ; and that the bulb is cupped on its lateral 



surface, near the front, on its under surface at the crus.
