the contrary, intended to project tlie mass without any loss of momentum, 

 by having a solid bony union and connection with the trunk : the blade- 

 bone of the fore limb in the horse appears remarkable for its dimensions 

 compared with most other animals, and the processes of the dorsal ver- 

 tebrse forming the withers, are of an unusual length and elevation, to 

 allow ample space for its upper parts to rest against, affording a strong and 

 noble character to the outline of the animal ; and such construction ap- 

 pears particularly necessary to receive the impetus of an animal of such 

 extraordinary weight and powers of action. 



The muscles which attach the fore extremities to the trunk, are con- 

 nected principally with the scapula, or blade-bone, which are spread in 

 radiating masses over all the adjacent parts of the trunk and neck, and 

 converging to a focus, are inserted not to the middle, but the superior parts 

 of the inside of the scapula, binding it strongly to the body, but at the 

 same time permitting its movements with the limb : and it appeaifs worthy 

 of particular remark, that the two shoulder-blades, viewed in connection, 

 form by their approximation upwards, a sort of arch along with the upper 

 parts of the limb, which receives the trunk within it, and the more it 

 gravitates from its own or any incumbent weight, these points of the arch 

 will be drawn the closer together, be Consolidated, and rendered the more 

 compact and stronger, that it would be next to impossible to break down 

 a machine formed on such principles ; and there appear other muscles 

 provided at the lower parts of the ehest, which passing beneath it, and 

 being attached to the limbs, suspend, or rather sling the body upon them, 

 giving thereby a freedom of motion not less necessary than strength 

 to the movements of the maehine. 



The contemplation of the uses of these muscles of the fore limb, and 

 those also of the arm of the horse, if o»r conjectures respecting them are 

 well founded, will throw somc light on the structure of the same parts in 

 the human anatomy, for very much the same parts exist in both, the horse 

 being ooly .defieient in the muscle of the clavicle, and possessing all the 

 others in the human arm, Nature grandly simple and tenacious of her plan 

 extends it through all her animals, modifying it variously, but not depart- 

 ing from it cven in the human structure; the human arms pendant on the 



sides
