tained by warm blankets and hot-water bottles to various parts 

 of the body, and especially tlie cardiac region. Warmth over the 

 heart is an excellent stimulant to the circulation, which, like 

 the respiration, is enfeebled by chloral, the heart, according to 

 Eajewsky, being more or less paralysed by the drug. If respi- 

 ration threatens to fail it should be maintained artificially so 

 as to allow time for the chloral to be excreted and the normal 

 functions to bo restored. 



Expt. I. Into two guinea-pigs of nearly equal size 0*6 c.c. 

 of a 50 per cent, solution of chloral (equal to about 5 grains or 

 0*3 gramme of chloral) was injected subcutaneously. 



Expt. II. Into two guinea-pigs, No. 1 weighing 655 grammes, 

 and No. 2 weighing GTO grammes, I'l c.c. of 50 per cent, solu- 

 tion of chloral hydrate was injected.
