AND LOWER EGYPT. 157 



The male is modelled on a scale somewhat 

 smaller than the female, but the difference is very 

 trifling. The tints of their fleece are likewise, in 

 general, not quite so deep. The testicles do not 

 appear outwardly. The penis, in its ordinary 

 state, is itself concealed in a very thick sheath: 

 when erected, it is fifteen lines long, and two and 

 a half round, at the root. The aperture of the 

 gland is formed by two cartilaginous rings ; the 

 prepuce has, in its upper part, two little hooks, 

 likewise cartilaginous, white, and three lines long, 

 which, bending forward, come to terminate nearly 

 on the brim of the prepuce itself. These hooks, 

 pretty thick at their insertion, terminate in a point 

 surmounted by a small yellow button, resembling 

 the antherae of certain flowers. The whole of the 

 prepuce is garnished, besides, with very small white 

 points, cartilaginous, and bent backwards toward 

 the root of the penis. From this singular conform- 

 ation of the parts, there is reason to believe that 

 the copulation of the jerbos must, like that of cats, 

 be accompanied with moments of pain, or even 

 that the gland, once inserted into the female or- 

 gan, cannot be for some time extracted, as is the 

 case with the canine species. 



With a mighty apparatus, relative to the small 

 size of the jerbo, for the business of propagation, 

 it is presumable, that their amorous affections are 



ardent.
