you that it varies materially in bulk in animals of the same 
species. 
Immediately anteriorly to the pituitary gland, the tractus optici 
cross the crura cerebri, and creep into sight from under the cor¬ 
pora striata, in order to form the optic nerves, with which indeed 
they are continuous. 
Posteriorly to the pituitary gland, the crura cerebri are found 
in perfect approximation, and so they proceed to the tuber annu¬ 
lare, giving out in their way the third pair of nerves. At the 
tuber they are joined by two large medullary chords from the 
lateral lobes of the cerebellum; but the nature of the union 
which there takes place cannot be understood until we have 
inquired into the structure and function of the cerebellum.

PARTURITION. 
June\^, 1832.—A spaniel bitch was brought to my infirmary 
to-day, which has been in great and constant pain since yesterday, 
making repeated but fruitless efforts to expel her pups. She is 
in a very plethoric habit of body; her bowels are stated to be in 
a confined state; and she exhibits some general symptoms of 
febrile derangement, arising, doubtless, from her protracted 
labour. This is her first litter. Upon examination per

16^A.—The bitch appears in precisely the same state as yes¬ 
terday, save that the medicine has operated freely upon the 
bowels, and the febrile symptoms have somewhat decreased. Her 
strainings are as frequent and distressing as ever. R. Sec.

last dose of this medicine my patient brought forth, with great 
difficulty, one dead pup ; upon taking which away from her 
she became so very uneasy that I was induced to return it to 
her. In about a quarter of an hour after this I paid her another 
visit; when, lo ! the pup was not to be found ; but a suspicious 
and tell-tale appearance in the mother’s eye betrayed at once
