" It may be necessary to state that at the time of examination all 

 the viscera had been preserved some months in a weak solution of 

 spirit. 



"The lungs are composed of three small lobes on each side. 

 The heart is flattened in form from behind forwards, measuring -A-ths 

 of an inch across its base, and but n vths in depth ; the want of apex 

 gives it a rounded and muscular appearance. The liver exhibits 

 two large and equally-sized lobes, and two smaller lobes. The sto- 

 mach, a single cavity, measures from the entrance of the oesophagus 

 round the great curve to the pyloric contraction 5 inches -rVths, 

 the greatest breadth C 2 inches T Vths, the depth 1 inch iVhs; the 

 spleen is small and elongated. The length of the small intestines 

 from the pylorus to the end of the ilium 3 feet 10 inches ; the cae- 

 cum and first portion of the colon are of large size, made up of three 

 half-circular convolutions, one central, with one of smaller dimen- 

 sions on each outer side, containing numerous cells and divisions, 

 strengthened by muscular bands and septa ; the whole length of 

 ccecum, colon and rectum^ measures 4? feet 10 inches. With the 

 exception of the ccecum and commencement of the colon, which as 

 I have stated are voluminous, all the intestines are of very small 

 calibre. The kidneys vary somewhat in shape ; one measures T Vths 

 of an inch in length and T Vths in breadth, that on the opposite side 

 is much more spherical. The specimen is a female, and the uterine 

 cornua measure each 3-f inches in length. 



" Of the skeleton, when mounted, the whole length from the 

 nose to the end of the tail is 13 inches -^ths the upper surface 

 of the cranium from the occiput to the inter-orbital space is in 

 form triangular and flat, the width .at the occiput 1 inch -rVth, 

 of the inter-orbital space -rVths, the whole length of the head 2 

 inches iVths, the mastoid processes and auditory cells of very 

 large size, the external meatus also large, oval, directed upwards 

 and backwards; the zygoma narrow and slender posteriorly, but 

 deep and stronger at its junction with the malar bone, which has 

 an ascending bony division between the orbits and temporal fosses ; 

 the nasal bones narrow, convex, and of parallel diameter; the lower 

 jaw is curved, broad and strong, the course of the incisor teeth is 

 visible, and the alveolar cavities of the molar teeth are well defined 

 externally ; the coronoid processes are wanting, apparently as if 

 broken off during the preparation of the skeleton, but have obviously 

 been of very small size; the condyle elongated from before back- 

 wards, the plate deep, and the posterior angle of considerable length. 

 Dentition -fi-f : the exposed portion of the incisors measures i-Vlis 

 of an inch in length ; the molar teeth are all made up of three parallel 

 portions or bony lamince, each portion invested with a thin coat of 

 enamel and closely united, the base of a molar tooth presenting six 

 lines of enamel and three cavities ; the anterior third of the first 

 molar tooth on each side, above and below, is smaller than the 

 other two portions, and gives to these teeth a triangular-shaped 

 crown ; the posterior third portion of the last molar tooth on each 

 side above is nearly round, and gives an increase of surface to these 



also;
