caught by the Middies of the Hashemy on her last voyage here : on 

 being cut open, there were no less than 43 youngsters disclosed to 

 view, all alive and frisky. Two of them were embalmed in the way 

 you see by Mr. Dawson one of the middies, and by him presented to 

 me. It was the opinion of those on board, from the appearance of 

 the voung folks, that they must have been occasional visiters of the 

 salt ocean, and had only retired to rest when discovered." 



Upon this latter point it may be remarked, that setting aside the 

 impossibility of such a thing on other accounts, the specimen is, so far 

 as a mere external examination can decide, in the fcetal state ; and, 

 consequently, unfitted for a residence for any time, however short, in 

 the water. Nor is such an idea in accordance with what we know 

 of the ovoviviparous fishes, being able to seek for nourishment them- 

 selves, and altogether independent of their mother, immediately 

 upon their being ejected from the womb.
