 Received June 11, 1879. 



(Abstract.) 



The effects of chloroform and ether on the pnlse, when employed to 

 produce anaesthesia in surgical operations, vary considerably. Some- 

 times the heart's force, estimated by the lowering of the primary rise 1 , 

 with due attention to the spring pressure, is greatly diminished, some- 

 times it is increased. The rate of the pulse is generally increased. 

 The rhythm is often deranged, sometimes very much, and so-called
