On the Viscera of a Female Ckimpanzee. 305 



The liver weighed 11 oz. Its main peculiarity, as com- 

 pared with the human subject, was the large size of the 

 caudate lobe. His has shown that in man it forms the 

 superior boundary of the foramen of Winslow. It was the 

 same here. This part of the lobe was small, and was placed 

 between the structures joining the transverse fissure and the 

 inferior vena cava. As the lobe passed towards the right 

 side, it became considerably enlarged. When the liver was 

 in situ this lobe was in contact with the right kidney, and 

 did not project beyond the adjacent portions of the right 

 lobe. Sir Eichard Owen ^ states that " fissures rather than 

 lobes are added to the livers of quadrupeds," and this seems 

 to be frequently the case. Portions of the liver which seem 

 to be very prominent when that organ is removed from the 

 body, do not project beyond the general surface of the liver 

 when it is in its natural position in the abdomen. The gall 

 bladder was large and slightly folded near the fundus. The 

 right kidney weighed IJ oz., and the left If oz. The 

 malpighian pyramids were blended together, and formed a 

 common ridge, which projected into the undivided pelvis of 

 the ureter. 



The spleen had three surfaces — gastric, splenic, and renal. 

 There were no notches in its anterior border. Its weight 

 was If oz. 



The only peculiarity of the superior aperture of the larynx 

 was the absence of the cuneiform cartilages in the aryteno- 

 epiglottidean folds. The true and false vocal cords closely 

 resembled those of the human subject. On passing a probe 

 into the saccule, this recess was found to extend upwards 

 above the level of the aryteno-epiglottidean folds as high as 

 the lower part of the tonsil. In man the saccule seldom 

 extends as high as the aryteno-epiglottidean folds. On the 

 left side the saccule communicated with a bursa in front of 

 the thyro-hyoid membrane. This bursa was not much larger 

 than it is in the human subject. The thyroid gland was 

 rather small. It consisted of two lateral lobes and an 

 isthmus. The latter has been described by Bischoff as 

 absent.
