199 



many of the growths either were dead, and all their soft parts entirely gone, or they 

 were but recently dead and in a putrid condition when the ship was docked and the 

 collections made.

In the foregoing list are given the organisms collected from ships' bottoms and 

 identified as far as the condition of the material would permit. By referring to this 

 list it wUl be seen that 48 species of animals have been found, in addition to 13 types 

 that could be classified only as to genera; while all of the plants found were algae, of 

 which 16 kinds were recognized.
