attachment, to the elephant in strength or to the camel in utility, 
he certainly takes precedence of them all in general utility and 
universality of application.” P. 4.

E. Asinus, the Ass.” P. 13. 
Electricity producible from the Skin of the Horse : — 
“ The skin of the horse is endowed with another remarkable 
and curious property — that of becoming electrically luminous under 
certain conditions. I believe this fact has not been hitherto noticed. 
It is somewhat similar to that previously known to belong to the 
integuments of the cat, but differing slightly in its manner of dis- 
charge. This animal electricity appears to be governed, in a great 
degree, by the condition of the animal and the hygrometrical state 
of the atmosphere. Upon using a stiff brush or currycomb on a 
dark night in dry weather, a gleam of electrical light will become 
perceptible, following the instrument, particularly when applied 
over the back, loins, and sides. The discharge of electricity from 
the back of a cat is accompanied with a crackling noise ; the usual 
attendant of electrical phenomena is isolated, or rises from separate 
points, and most evidently inflicts a painful sensation on the 
animal : in the horse no such detonation is heard ; the discharge is 
general, from the whole surface in contact with the instrument, and 
does not appear to be at all painful to him.” P. 19. 
Use of the False Nostrils : — 
“ On putting the fingers into the nostrils, at the upper and out- 
ward part, they pass into blind pouches of considerable dimensions. 
These curious cavities have nothing to do with smelling, because 
they are lined with a reflection of common integument ; but they 
may possibly be of use in mechanically distending the external 
entrance of the nostrils, and thus materially facilitate respiration 
during violent exertion. They are also brought into use when the
