the weight of the rider and of his arms, accoutre- 
ments and baggage... The well known experiment of 
Marshal Saxe, shows the maximum of horse power, 
in this respect. He directed, that a strong and vigo- 
rous horse, while in motion, should be loaded untill 
he fell. The effect was not produced, until the load 
amounted to 1,200 weight. (1) 
IL. Of the Mule. 
This is the well known product of a jack pe a 
mare, or ofa horse and a jenny, the name given to a 
female ass. ‘Their advantages over the horse are, 
that they are more patient of hunger and heat; are 
less nice or delicate with regard to their food; sus- 
tain better and fora longer time, fatigues of all kinds; 
carry heavier burthens; are more sure footed; less 
liable to sickness and live to a much greater age. In 
Jialy and Spain, they are much employed in harness, 
and in the mountainous parts of those countries, for 
the saddle. . Their yalue and qualities, however, de- 
pend principally on those of the size: if he is large, 
active and strong, his progeny will be proportiona- 
bly yaluable. Nothing therefore can be more ill- 
judged than employing small jacks.(2) 
III. Of the Cow and the Ox. 
It was long supposed, that this animal was a native 
of Europe, and that the Auroch, found wild in the 
forests of Poland, was the type of the species. ‘The

race of inferior size, but ef great powers. See Sonini’s Supplement to Buffon on this
