 any great reliance. The growth of the incisors 

 shows the colt to be " rising four ;" the evidence de-

 unique ; at all events I am aware of the existence of 

 no similar specimen ; and it is to be lamented that 

 the growth of the incisors, from the earliest period,

 specimen it is curious, but as a premature and ex- 

 traordinary development, it cannot be opposed to a 

 general rule. Children have been born with three 

 legs, or joined together at various parts; but the 

 race of men are nevertheless described as having two 

 inferior extremities, and as being independent in

 a curiosity, and, until it is proved to be the exem- 

 plification of a general rule, must not be made the 

 basis of a general deduction. Such occurrences, how- 

 ever rare, nevertheless deserve consideration ; and 

 had the animal last alluded to been trained, there is 

 no doubt any qualified judge would have pronounced 

 it beyond the actual age. Therefore, gentlemen
