SPHYGMCGRAPHIC OBSERVATIONS.

quite dead, only very feeble respiration being seen, and the eyelids contracting 

 ■when the finger touched one of them or the cornea. The caruncula lachrymalis 

 covered almost one-fourth of the eye. At 3.20' it was lying as if quite dead ; 

 the surface quite cold ; the limbs flaccid ; and the pulse inappreciable when it 

 gave one or two yawns. At 3.23' it gave a short, weak, low howl, and inamc- 

 diately after the cornea was found insensible. Post-mortem was made between 

 five and ten minutes after death. On opening the body, a small quantity of 

 urine trickled Irom the urethra, probably from pressure on the bladder, which 

 was quite full. The lungs were of a natural colour. The heart was well filled 

 with blood in both cavities. The venous system turgid. The heart contracted 

 readily on irritation. At 4 p.m. the dissection was interrupted. It was resumed 

 at b.T. The pericardium, when opened, contained a small quantity of serum, 

 about one or two drachms. The heart still showed signs of contractility. At 

 4 P.M. the diaphragm contracted readily on irritation of the phrenic nerve ; the 

 CBsophagus and thoracic duct contracted on pinching them. 



Jan. 26. — One centigram of digitaline was injected into the cellular tissue of 

 the loins of a rabbit. It produced no apparent effect.
