Exp. 42. (R. Gastroc). Nov. 15, 1906. Room temp. 15" C. One minim 

 0-01 per cent. liq. strych. injected just before making the preparation. 

 The same-side reflex had been ah'eady recorded several times with the 

 cord at different temperatures (see p. 28). No crossed-reflex could be 

 obtained until a second dose (of 2 minims 0-01 per cent. liq. strych.) 

 had been injected, and then at first it could not be obtained with any 

 streno-th under 14,000 units.

The crossed-reflex effects were in the first two responses very weak ; they then 

 became stronger, though not always attaining their maximal strength 

 until late.^ Their duration was somewhat shorter than that of the 

 uncrossed-reflex effects, but, with the exception of the first two, was 

 longer than the direct effect. 



1 The t when it occurs in the tables signifies that the moment at which the effect 

 became maximal was deferred.
