the place of detailed comparison and merely the general results will 

 be indicated. The Purkinje cell of the cerebellum was again the 

 type studied in detail and six hundred cells were diagnosed in each 

 case, two hundred each from the worm, the uvula . and the biven- 

 tral lobe.

In comparing figures from different animals, the very wide varia- 

 tions possible in the collective cellular states of outwardly normal 

 ones must first be borne in mind. For example, Experiment 30 a, an 

 undisturbed control from the same litter as Experiments 29 and 30, 

 shows a high state of functional activity, its cells in general being- 

 more advanced than either of the animals treated with the drugs. 

 Yet no conclusions whatsoever of a negative effect of sarcolactic acid 



x ) From Table II, Studies on Recuperation. Jour. Med. Res., 'Vol. 24, 1911. 



2 ) One thousand cells instead of six hundred were counted. 



3 ) From Table I, Neurocytological Reaction in Muscular Exertion, Am. Jour. 

 Phys., Vol. 25, 1909. Senile and recovery types not then identified. Known youth 

 precludes excess of the former, while known absence of previous strain would make 

 the latter unimportant.
