Jackson^ s Anatomical Description 



the middle of the posterior edge of the extreme right 

 lobe^ mostly on the upper surface, but just appearing also 

 on the under ; it was in a great measure imbedded in the 

 substance of the organ, of a pyriform shape and three 

 inches in length; in the male tortoise it contained a little 



yellowish, watery fluid, and in the female gijss or giij of a 



thin, dark fluid; parletes firm, and the inner surface quite 

 smooth except for several small, rough prominences. 

 Bile ducts not satisfactorily traced- Vena portse quite 



large. 



The situation of the Spleen was very peculiar, being 

 found in all three of the specimens in the right side of the 

 abdomen, between and rather below the coecum and a 

 convolution of large intestine, with both of which it 

 seemed to be intimately connected. The color was deep 

 red, consistence firm, and in form and apparently in struc- 

 ture it resembled the same organ in the human subject - 

 It measured, in the female, five inches long, two and a 

 half wide and one and three fourths inches in thickness. 



The Kidneys were situated just in front of the sacrum, 

 not far from the vertebral column and obliquely to the 



direction of it.

neum, but otherwise closely connected with the neighbor- 

 ing organs. The external tunic being removed, they were 

 found to be much lobulated. Internally there was no divi- 

 sion into cortical and tubular portions and there was no 

 proper pelvis. In the female they measured six inches 

 in length and four in width. The ureters were five inches 

 long, large enough to admit a full-sized catheter and ter- 

 minated in the urethra near the opening of the oviducts, 

 but on the side roost distant from the bladder ; so that 

 the urine, in order to reach that organ, would have to take 

 a perfectly retrograde course.
