in this case occupying a volume, one might almost say, greater than the glandular hepatic 
organ itself. As I have shown in 7’richechus, there is a mid septum interiorly, with a 
free opening, however, between ; and each sac has diverticular pouches in communica- 
tion with the various segments of the much divided liver. The capacity of the two 
chambers is such that, on being injected, I was utterly astonished and confounded as to 
where the material was being sent to. Subjoined is the memorandum taken when at 
work ; and the drawings, figs. 48 and 72, supplant lengthened description. 
‘“‘ Hepatic sinuses 14 inches across in a straight line; that of the right side alone is 
8 inches, interspace 1 inch; hence left, above, 5 inches long. ‘There is a deep and wide 
fissure behind; and each from this view is semilunar or stomach-shaped, the cardiac 
and pyloric curvatures being represented by the veins that enter the different lobes of 
the segmented liver. In front, 7. ¢. below, there is scarcely any fissure; but a strong 
white fibrous band, an inch broad, runs up the middle, being derived from, or a dupli- 
cature of the abdominal surface of the diaphgram. Circumference of right half when 
distended 11 inches, the left being half an inch less.” 
The hepatic plexus of nerves lies beneath the portal trunks; and twigs of these ramify 
around the vein while being sent to the numerous hepatic lobes. Minute branches of 
nerves are also derived from the hepatic plexus, which accompany the bile-ducts, and 
lie superficial to the portal vein, and even to the arterial trunks.

a. Hyoid arch.—This arch is built up of nine osseous and four cartilaginous elements. 
A taper pointed cartilage 0-4 inch long articulates the arch with the tympanohyal of the 
skull. The stylohyals united with these cartilages are subcompressed, digit-shaped 
bones, each 1:2 inch long, and with a knobbed extremity distad from the skull. ‘These
