TABLE 11 
Giving for several species of mammals the adult body weight and brain werght, the 
average cortical thickness and the name of author from whom the data for the 
cortical thickness or for the brain and body weights were cited, arranged in the 
order of decreasing body weight within each family of mammals. 
The abbre- 
viations of the names of authors are as follows: B = Brodmann (’09), I = Isen- 
schmid (11), L = Lewis. (’79), 
M = Marburg, (12), S = Sugita (17a, 
18 a, MS.)

‘The body and brain weights of some animals were not given by the author 
who has given the cortical thickness. 
were taken from the list given by Weber (’96). 
2 According to Lewis (’79), the values given here without brackets were taken 
from Meynert and show the value measured on the slide and the values given 
within brackets were obtained by his own observation and represent the natural 
depth of the cortex.
