and they were either not made known elsewhere or in places 

 that are no longer accessible. 



In this table the body weights are mostly small for the body 

 heights, which will probably be owing to the fact that most examined 

 men and women did not possess a normal weight at the time of 

 their death. According to this and the following table the relative 

 weight of the mnscles in each sex is, however, bari'ing exceptions, 

 a little variable property, even in more advanced age. Nothing else 

 is, indeed, to be expected from so prominent a system of organs 

 as that of the mnscles, which as regards qnantity, participates for 

 about a third of the weight in the composition of the body, and 

 the development of which is in close connection with that of other 

 important parts of the bulk of the body, as the skeleton and 

 many others. 



The sexual ditference in the relative weight of the muscles assu- 

 mes the greater importance in consequence of their pieponderant 

 influence on the bulk of the body. This difference is very conside- 

 rable. In ratio to the same body weight men are no less than over 

 22',,, more muscular than women according to the averages in 

 Table III. 



It is very much to be regretted that in THEirp:'s for the rest very 

 careful determinations of weight of the muscles, from which I com- 

 posed Table IV, the body weight could be stated in but a single 

 case. Theilk himself calcidates the average relative muscle weights 

 by simply assuming, according to the general values given by Quetelet, 

 the average body weight to be 68 kilograms for his 8 vigorous men, 

 suicides or having died of an acute illness, and the average body 

 weight to be 54 kilograms for his 4 vigorous women, who had died 

 of an acute illness; he then finds (p. 223): "Die Gesamtmuskulatur 

 des erwachsenen kraftigen Weibes scheint also dnrchschnittlich noch 

 nicht ein Drittel des Körpei-gewiciits zu erreichen, wahiend sie beim 

 erwachsenen kraftigen Manne dnrchschnittlich mehr als ein Drittel 

 des Körpergewichts betragt". It appears possible to approximate the 

 real weights still somewhat more closely by taking into consideration 

 the individual heights and what is further noted about every indivi- 

 dual, for the estimation of the weights. The number of the deter- 

 minations serviceable for my purpose is then confined to 4 men 

 and 4 women. Theile's man N' 8 has not been inserted in Table IV 

 on account of his, in comparison with the other men and women, 

 high age of 54 years. Estimating his weight, with a height of 160.2 

 cm., at 57 kilograms, he is found to have a relative muscle weight 

 of 38 v..
