Apart from a few exceptions the relative weights of the muscles 

 according to the data ofTflEiLKare lower than those according to the data 

 of Wklcker. This is partly owing to the circumstance that the body 

 weights given by Welcker are in general' low for the body heights, 

 but probably to a greater extent to another circumstance. Wei,cker's 

 muscle weights, with the exception of II. 1 and II. 5, were, namely, 

 determined indirectly, with a certain necessary additional weight on 

 account of the loss of the weights of the other organs, which have 

 been subiiacted from the body weight; Theile, on the other hand 

 determined diirctli/ the singular muscle weights, in which laborious 

 manipulations some loss of weight, at least through evaporation, is 

 inevitable. 



These deviations, however, applying equally to both sexes, the 

 ratio between them is certainly but little changed by this difference 

 of the methods. Welckkr's man III. 5 must have been an exception- 

 ally powerful individual, indeed, just as Theile's N°. 3, but the 

 high value of HI. 5 is balanced by the low values of II. 1 and II. 2. 



Hence «Man is twenty-tnw per cent according to one, twenty-seven 

 per cent according to the other series of determinations per unity 

 of body weight more muscular than Woman. That these results, 

 even apart from the uncertainly of the estimations in question, 

 founded as they are on a small number of observations, may still 

 depart somewhat from llie general average, notwithstanding the 

 prevailing constancy of the relative muscle weight within each sex, 

 needs no further demonstration. 



Nor has perfect certainty been attained as regards the average 

 body weights of European men and women. But when with 

 Lapicque the averages are put at 66 and 54 kilograms, it is found 

 that these values are |)recisely in the same ratio to each other as 

 the average relative muscle weights according to Theile's determi- 



nations. In fact — is =1,2222 and --— is = 1.2223. 



If then the male body per unity of weight, has 227„ more muscle 

 weight than the female body, the weight of the former is, besides, 

 absolutely greater than the latter in the same ratio. 



In his excellent handbook on anthropology ') Rudolf Martin 

 assumes as the average weight of European woman 52 kilograms,
