toward the deeps. At any rate, its body is so deli- 

 cately constituted that it is utterly unable to with- 

 stand the strain imposed by prolonged retention in 

 the comparatively pressureless waters of the ex- 

 treme shallows or under the similar conditions 

 which prevail in the precincts of the artificial tank. 

 The tremors I have told about are doubtless indi- 

 cations of this strain; doubtless, too, the collapse 

 of the creature is caused by the same disorder.

Thus far in this monograph I have set down 

 nothing regarding the habits or history of the sub- 

 ject otherwise than that which relates solely to the 

 physical. These physical characteristics are essen- 

 tially few and simple, as the reader has doubtless 

 observed — so few and simple in fact that a sum- 

 mary at this point gives us merely the following: 



1. The sea-horse, Hippocampus hudsomus, is 

 found in the waters of the Atlantic Ocean along 

 the shores of Eastern United States, from Long 

 Island Sound to the Gulf of Mexico. 



2. The young hatch from eggs deposited by the 

 female in the ovigerous pouch of the male. Mating 

 occurs in midsummer.
