of a large teacup. To the left side, and attached by a long distinct fold 

 of peritoneum, in which are contained many arborescent vessels, lies the 

 oviduct, beginning above by a bilobate, soft, gelatinous orifice in the 

 peritoneal fold enveloping the ova, and descending and gradually widen- 

 ing into a large ovisac ; the whole tube is 2 J feet long and opens by a 

 narrow but dilatable orifice into the cloaca below. The interior of the 

 lowest part was very gritty in feel, from the particles of carbonate of 

 lime secreted there for the formation of the shell. The lowest part of 

 the ovisac has a strong, well-developed muscular coat, which diminishes 

 and almost ceases at the upper part. 



The kidneys are elongated, flattened, glandular masses, thirteen inches 

 long, and an inch and a half wide, lying deeply seated, and extending 

 from the posterior edge of the diaphragm to the anterior extremity of the 

 pelvic cavity ; they are brownish-red in colour, rough on the surface, and 

 the left is divided into two lobes ; each is bordered by a large vein, which 

 passes up to join the cava, posterior to which the ureter arises, at the 

 junction of the inferior and middle third, from a well-marked pelvis, 

 into which open several infundibula, which can be traced back to calyces. 

 The medullary matter is not arranged in pyramids, nor do its tubes con- 

 verge to papillae. The ureter passes down approaching the mesial line, 

 is reddish-white in colour, and cylindrical in shape. The renal artery 

 is a branch of the aorta, and enters posterior to the ureter. The kidney 

 is enveloped in a fatty capsule, which is very dense in front, and binds 

 it down in its place, separating it from the ovaries. The supra-renal cap- 

 sule is at its upper part, flattish-o val in shape, three inches long, and deep 

 orange in colour; its inner angle passes considerably farther back than 

 its external, and its tipper surface is in contact with the diaphragm. 

 There is no distinction of cortical and medullary matter in its structure. 

 Superior to the kidney, on the left side, lies the spleen, enclosed in a 

 layer of peritoneum derived from the stomach, and elliptical in shape, 

 narrower above than below, the long axis being directed downwards, 

 forwards, and to the right side; it is three inches andahalfinlengthby 

 one in breadth ; it is surrounded by a capsule of peritoneum, and by a 

 proper fibrous coat underneath ; it is supplied by a branch of the celiac 

 axis, and is made up of a soft, spongy, vascular tissue of a deep red 

 colour. 



The generative organs of the male consist of two testes, placed above 

 and a little external to the kidneys, invested in a strong fibrous tunica 

 albuginea, about three inches long and If inches in width; from 

 the outer and back parts of these organs, the tubes pass to form a large 

 epididymis, which is prolonged for three inches below the testis, and nar- 

 rows into the reddish soft vas deferens, which runs down almost parallel 

 to the ureter, and opens into the cloaca a little external and anterior to it ; 

 there is an elongated and pointed eminence, more than a quarter of an 

 inch long, seen on the mucous membrane of the cloaca, and at the apex 

 of it is the orifice of the vas ; the opening of the ureter is much smaller 

 in the male than what it is in the female. The two vasa deferentia open 

 on either side of the groove in the intromittent organ, which com- 

 mences by two firm fibrous crura attached to the pubis, then turns
