MAMMALIA— SEAL. 203 



pounce with her paws upon the head of the marten, in such a way that the 

 claws may destroy or wound its eyes, while her teeth are embedded in its 

 neck ; and if she can accomplish that, the fate of the marten is decided. 

 That, however, if done at all, must be done in a moment ; and if it be lost, 

 there is no repairing the mistake. The spring of the wood cat is larger than 

 that of her opponent, and the cat takes up her position so that she shall, 

 if possible, alight upon his head with her full spring and impetus. To dis- 

 tract her attention, he keeps moving his head from side to side, and if he 

 succeeds in his object, he rushes to close quarters by a side movement 

 If the spring of the cat takes proper effect, there is a struggle, but not ol 

 long duration ; and it is the same with the opposite result, if the cat miss 

 and the marten fasten, during the short pause of exhaustion after the 

 spring." 



A singular animal has recently been discovered in the island of Java, 

 which seems the connecting link between the cat and ferret tribes. It has 

 the lengthened muzzle, and slender body of the latter, Avith the sheathed 

 and retractile claws of the former. Dr Horsfield denominates it Prionodon 

 gracilis.
