Remaiks. 



Pulse very markedly intermittent, 

 and the mercury falls at each in- 

 termission as low as 4. 



Pulse gives one stront; beat and 



then li or 4 feeble ones. 

 A drop of prostatic mucus exudes 



from the point of the urethra. 

 Pulse Tery intermittent. Animal 



shivers every minute, or even 



more frequently. 

 The hsemadynamometer stopped 



working. 

 Eeadjusted the apparatus. 



Pulse intermittent. 

 Animal continues to tremble. 

 Oscillations more steady. 

 Clot again formed. Almost con- 

 stant tremors. 



The apparatus was cleaned, and again adjusted at 4.40, but the nozzle came 

 out, and there was a gush of blood, and as this would have thrown some fallacy 

 into the future reading of the mercury, the artery was ligatured, the wound 

 stitched, and the dog released from the table. It lay for a few minutes, and 

 then began to try and get off the muzzle. When this was removed, the dog 

 rose and walked about. It seemed rather stiff at first. 



Exp. IX. — March 20. — The dog operated on on the 9th, having recovered, 

 was put under chloroform, and the carotid exposed. The dog was then allowed 

 to come out from the chloroform, which it did at 2.15 p.m. Instead of digita- 

 line, the extract obtained from commercial tincture of digitalis was employed; 

 the tincture being gently evaporated, and the extract then dissolved in water 

 and injected. The hsemadynamometer giving the mean was employed.
