the fact that excitation of any one point elicited rarely more than one 

 movement and only of one segment, e.g., simple flexion of the elbow. 

 Consequently, any sequence of movement or march was conspicuously 

 infrequent. 



Finally, the character of each movement and its localisation was 

 recorded. 



After the cortex had been removed, we proceeded to stimulate the 

 fibres of the internal capsule, and the results obtained confirmed 

 those obtained from the bonnet monkey, and at the same time showed 

 the relative position of the cortical areas. 



The internal capsule was exposed by removing half of one hemi- 

 sphere by a horizontal section ; the outlines of the basal ganglia were 

 then transferred to paper ruled with squares of 1 millimetre, and the 

 resulting movement obtained by stimulating each of these squares 

 contained in the internal capsule was recorded. The movements 

 obtained correspond generally with the results which we have in 

 another paper presented to the Royal Society and read on December 12, 

 189. 



VII. " A further Note on the Influence of Bile and its Consti-

Ox Bile and Pancreatic Extract. 



In a previous communication* we have pointed out that in the pig 

 the presence of bile or bile salts hastens the digestion of starch by 

 pancreatic extract, the amount of dextrine and of sugar being con- 

 siderably and proportionately increased. The same holds good for 

 ox bile salts and extract of ox pancreas, so far at least as the increase 

 in the amount of sugar is concerned, and for human bile and pan- 

 creatic extract (pig's). Experiments were conducted in the same 

 manner as those with pig's secretions. In one experiment four 

 vessels, A, B, C, D, containing 100 c.c. distilled water in which 

 2 grams of starch had been boiled, were taken. To B 2 per cent., and 

 to C 4 per cent., of ox bile salts were added and dissolved. Equal 

 quantities of glycerine extract of pancreas were added to A, B, and C,
