M. St-Hilaire on a Polydadylous Horse. 25 



perfectly well formed, and indeed for the Burman race ra- 

 ther handsome. The whole family were sent by the King to 

 the residence of the mission, where drawings and descriptions 

 of them were taken. Albinos occur now and then among the 

 Burmese, as among other races of men. We saw two exam- 

 ples. One of these, a young man of twenty, was born of Bur- 

 mese parents.. They were ashamed of him, and considering 

 him little better than a European, they made him over to the 

 Portuguese clergyman. The reverend father, in due course, 

 made him a Christian. 



Art. IV. — On the Foetus of a Polydactylous Horse having the 

 Toes separated by a Membrane. By M. G. St-Hilaire, 

 Member of the Institute. 



The extremely brief notice of this rather singular specimen of 

 a peculiar kind of deformity in the horse scarcely furnishes a 

 sufficiently accurate account to be submitted to our readers. 

 It would seem that the distinguished naturalist to whom we 

 owe the publicity of the very singular specimen alluded to, 

 having proceeded to the south of France for the express pur- 

 pose of conducting in safety to Paris the camelopard, of which 

 a notice will be found in another part of this Number, examin- 

 ed on his route whatever museums existed ; and in that belong- 

 ing to the veterinary school at Lyons he met with the foetus, 

 the peculiar mal-conformation of whose feet gave rise to his 

 brief notice. 



For the benefit of those not sufficiently acquainted with the 

 doctrines of comparative anatomy originally laid down by 

 Aristotle, and likewise in order to render M. St-Hilaire's 

 notice intelligible to the generality of our readers, we shall 

 very briefly state the osteology of the horse's foot, and com- 

 pare it with those of other animals, and with man. 



The pectoral extremities of the horse, or his fore-legs, ar6 

 composed essentially of the same elements as the human arms, 

 and the bones of each may be arranged and described in this 

 way : —
