THE ZOOLOGIST.

* The smaller Petrels are well known to make a most active use of their 

 legs while on the wing, often dangling them beneath them, or seeming to 

 walk on the water like an Albatross. See Mr. Ogilvie Grant's account of the 

 Frigate Petrel, Pelagodroma marina ; " On Birds observed at the Salvage 

 Islands," ' Ibis,' January, 1896, p. 51.
