Dr. V. Harley. The Influence of Intra-Venous [June 7 r 

 Experiment 1. 



The only nerve symptoms after the sugar injection were manifested 

 in vomiting and muscular tremors. These were not accompanied by 

 coma or any other symptom. 



The quantity of carbonic acid found in the standard specimen of 

 blood was 37'380 per cent., whereas, in that taken an hour after the 

 sugar injection it was only 27*006 per cent., that is to say, a diminu- 

 tion of 10'374 per cent, in the amount of carbonic acid followed upon 

 the intra-venous injection of the sugar, while the blood withdrawn 

 five hours later contained 34'357 per cent, of carbonic acid, this being 

 only 3*023 per cent, less than that in the standard blood. The 

 carbonic acid, thus tending to return to the normal amount, showed 

 that the influence of the sugar on the carbonic acid in the blood is 

 merely temporary. 



The quantity of oxygen in the standard blood was found to be 

 22 '280 per cent. An hour after the sugar injection it had fallen to 

 17'071 per cent., thus giving a diminution of 5'209 per cent. Five 

 houi's later it was still further decreased, being only 14'886 per cent. 

 Consequently, in this respect the effect of the sugar on the oxygen is 

 different from that upon the carbonic acid.
