is 1.708 times larger for man than for woman ; of both sexes 

 "kriiftige Leichen" were compared. In the "muskelkiaftige" men 

 and women of Thkii,k the liomonymous mnscles had the weights 

 indicated in Table VII. 



TABLE VII. — Muscle weights (in grams). (From determinations by F. W. Theile) 



The average weight of the three mnscles is 1.765 times greater for 

 the men than for the women. When it is assnmed that in proportion 

 to the greater bodily lengths, the muscles were on an average 1.069 

 times longer for the men ^), we find the area of section on an average 

 1.651 times larger than for the women. This latter value comes verj* 

 near the value 1.708 found for the increase of the average area of 



') Of the man N". 5 the gastrocnemius had not been weighed separately. I chose 

 for this N*'. 7, "Mann von melir als mittlerer Grosse", for whose height I 

 assumed 175 cm. The average height of these four men then becomes 168.6 cm.; 

 the average height of the four women is 158.9 cm. The ratio of the lengths of 

 the limbs of these men to those of these women may thus be put at about 

 170 : 159 = 1.069.
