In Table Il. will be seen the influence of sex upon the 
results, and in order to reduce the number of males to that 
of the females, and to avoid anything like a selection, every 
fourth male, as recorded in Table I., was omitted. This 
Table has also been arranged according to the weights of 
the gastrocnemius muscles; and it will be seen that the total 
weight of the female frogs before the experiment was 18 
oz. 2 dr. 9 grs., whilst that of the male frogs was only 12 oz. 
2 dr. 25 grs. The total weight raised by the female frogs 
was 171 oz., by the male frogs 123 oz.; but the weight of 
the gastrocnemius muscles in the females was 2 dr. 222 grs., 
that of the males 1 dr. 30 grs., indicating that the muscular 
power of the males, as compared to that of the females, 
showed that 1 gr. of muscle in the males could raise 656 
-grs., whilst in the females 1 gr. raised only 579. 
From these experiments we find that the weight of the
