 Country people talk mucli of a water-snake, but, I am pretty 

 sure, without any reason ; for the common snake (coluber 

 natrix) delights much to sport in the water, perhaps with a 

 view to procure frogs and other food.* 



I cannot well guess how you are to make out your twelve 

 species of reptiles, unless it be by the various species, or

 Surrey ; and Bay admits there are such ia Ireland.

As ib proof of the accuracy of Mr. "White's observation, that snakes pro- 

 bably go into the water to procure food, T may mention, that a gentleman 

 lately saw one of these reptiles in a stream and under some weeds, conse- 

 quently under water, watching for prey; Having observed it for some minutes, 

 he took it out of the water, when it not only emitted a most unpleasant stench, 

 but struck at him several times like a viper. — Ed,
