208 DR. J. ANDERSON ON MACACUS BRUNNEUS. [Feb. 20, 



into which it opens close to and only a short way (3 lines) below the 

 bile-duct, and 1" 4" below the pylorus. 



The liver has an extreme breadth of 4" 9'", while the anteropos- 

 terior dimension of the middle lobe is 2" 5"'. The left lobe has a 

 general resemblance to the same lobe of the human liver, and is 

 somewhat triangular and much concave on its under surface. The 

 right and left lobes are deeply cut off from the middle or cystic lobe, 

 which is twice as large as the lateral lobes. The auterior margin of 

 its left third is rather deeply cut, and marks the position of the sus- 

 pensory ligament. The upper surface of the two thirds to the right 

 of the latter is obliquely crossed by a well-defined groove. The 

 right lobe is quadrangular and very slightly larger than the left lobe, 

 and has an elongated triangular lobule, lying on its under surface 

 from within outwards, and above it a tongue-shaped, smaller lobule, 

 placed before and along the external margin of the lesser curvature. 

 These two lobules have a common origin, from which they diverge in 

 opposite directions ; and between and above them there is still another 

 and smaller lobule. The middle or cystic lobe is deeply grooved 

 for the gall-bladder, which occupies the middle of its under surface. 

 The gall-bladder is long and of nearly equal width throughout. 



The orifice of the hyoid pouch is immediately above the anterior 

 end of the vocal cords, from which, when the hyoid and epiglottis are 

 divided and the parts are laid aside, the floor of the passage leading 

 into it is seen to be continuous with the convergence of the vocal cords 

 of the two sides. When the larynx is at rest the orifice of the pouch 

 is very small and contracted, and it appears as a mere point at the 

 lower end of the epiglottis; but when the parts are divided' it is 

 capable of great distension. The hyoid is much excavated, forming 

 almost an osseous bulla and fully one half of the anterior and superior 

 walls of the pouch, the lower, very distensible wall being formed by 

 a very delicate membrane. The ventricles are only 2" in depth, and 

 present nothing worthy of remark, beyond that they are simple lateral 

 crypts between the superior, or false, and the true vocal cords. 



The right lung is divided into three distinct lobes, while the left 

 only shows two sections. The uppermost lobe, however, of the left 

 lung is deeply incised into two, so that it is almost trilobular. The 

 inferior lobes of the two lungs are of nearly equal size and are py- 

 ramidal ; but the anterior- inferior margin of the right lobe is incised 

 for the reception of the external lobule of the azygos lung, while 

 that of the left is entire. There is no appreciable difference between 

 the length of the two lungs, the right measuring 3" 2'" and the left 

 3" 2f-"\ The azygos lung is most closely connected with the inferior 

 lobe of the right, and consists of an elongated (1" 6'"), three-sided, 

 and downwardly tapering figure, with a lobule on either side of its 

 attachment, one external and the other posterior. The body and 

 posterior lobule fit in between the two inferior lobules of the right 

 and left lungs, and the external lobule into the incision on the inner 

 side of the inferior lobule of the right lung. 



The glans penis is ] " 2'" in length and about 3 lines in breadth at 

 its widest place near the base. The upper surface is marked by a
