Notes on Leach's Petrel ( Cymochorea leucorrhoa .)— Under date of 
July 29, 1880, Mr. Manly Hardy of Brewer, Maine, gives me the following 
notes on Leach’s Petrel. The facts regarding incubation, are I think, new, 
and go to show that, as with the Phalaropes, the female Petrels have 
strongly imbibed the spirit of the nineteenth century. 
“ I have lately had quite a number of Leach’s Petrels taken on the nests 
and find some things which are not mentioned in such books as I have 
access to. In the first place, the males do most, if not all, of the incubating. 
In a number received the 1st of June, five out of six were males. Think¬ 
ing that, like Pigeons, the males might perhaps all sit at the same time, 
I had another lot sent me about June 15, and again, of twelve specimens 
seven proved to be males. A careful examination showed that while the 
under plumage of the females was in every case perfect, each male had 
on the lower part of the breast a bare spot large enough to cover the egg. 
“ Some writers mention their ejecting oil when irritated. 1 (ind that 
either sex can eject at least one-eighth their bulk of very pure reddish oil, 
and that it is given forth equally freely when the bird is killed by chloio- 
form. I think that it is probably intended to.serve as food for the young.”
