EQUUS ZEBRA. 165 



many longitudinal folds, which become smaller and smaller towards the 

 fundus, where they are entirely lost. The cornua are like those of the 

 mare, the uterus dividing into two equal branches, which become 

 smaller as they pass on, till at last they become very small. The 

 ovaria are smooth bodies, a little oblong, and, as it were, bent on them- 

 selves, so that their two ends almost meet \ Between the sacrum and 

 the first lumbar vertebra there is a considerable motion up and down, 

 but not laterally 2 . 



The Zebra [Equus Zebra, Linn.], 



It is at present impossible to say whether the zebra is an ass, horse, 

 or neither ; if it be neither, it is of the same genus ; for it has been 

 known to breed with one ; that is to say, a male zebra with a female 

 ass. 



Loose note. — There was a curious circumstance attended this process. 

 He would not have anything to say to the female ass at first ; and to 

 entice him (or to deceive him, if it was upon principle), they painted 

 the female similar to himself, and then he covered her ; but the experi- 

 ment went no further 3 . 



If we consider them anatomically, we shall not be able to determine 

 this question. The zebra has the two cavities on the sides of the 

 fauces which answer to the [faucial terminations of the] Eustachian 

 tubes in the horse and ass. 



The cuticle of the oesophagus is continued into the stomach for some 

 way, and principally on the fore part, running towards the pylorus, and 

 terminating in an edge a little raised, as in the horse and ass. 



The caecum is above 2 feet long i , and is turned up towards the carti- 

 lago xiphoi'des, which it reaches upon the fold of the colon, being attached 

 to this fold by a mesocolon. The colon at its beginning is attached to 

 the loins, kidney, &c. and, as it passes up, it becomes loose, still passing 

 up towards the sternum, when it crosses the abdomen, before the

2 [Besides the usual articulations there is a concavity at the back part of each 

 diapophysis of the last lumbar vertebra, for the reception of an articular convexity 

 from the fore part of those processes in the first sacral vertebra : this transverse ex- 

 tension of that joint is shown in Nos. 3180, 3181 (Horse), Osteol. Series.]

 1821, p. 20, for an account, by Lord Morton, of the impregnation of a mare by a 

 male quagga, the hybrid offspring of which is figured in an oil-painting now in the 

 Royal College of Surgeons. This, and paintings of the mare's subsequent offspring 

 by an Arabian stallion, are described by the Editor in his ' Synopsis of the Museum 

 of the College,' 8vo, 1850, p. 99.]
