while he spent all his leisure time on the study of the birds 
of the surrounding district. Entering into relations with 
Dr. Cabanis, of Berlin, Euler contributed to the * Journal 
fiir Ornithologie "* .a series of excellent field-notes on the 
birds of Brazil and their nesting-habits and eggs, which were 
commenced in 1867 (see J. f. O. 1867, p. 177). In 1877, 
not being able to continue his work at Cantagallo, Euler 
moved to Bio de Janeiro, and subsequently prepared the new 
edition of his ornithological papers, which was published by 
Dr. V. Ihering (to whom we are mainly indebted for these 
notes on Euler's life) in the fourth volume of the ' Bevista 
do Museu Paulista' (see ^bis,' 1901, p. 132). 
Of Euler's collections, some went to the Museum at 
Berlin and others to the National Museum at Bio. Euler 
was an excellent field-naturalist and observer, but had little 
disposition for strictly scientific ornithology. 
Lt.-Col. the Bt. Hon. Edward Henry Cooper, P.C, of 
Markree Castle, Colloony, Sligo, and 42 Portman Square, 
London, who died on February 26th last, became a Member 
of the B.O.U. in 1880. He began experiments with a 
view to introducing the Black Grouse on his Irish estates 
more than thirty years ago, and at first obtained specimens 
from Scotland. More recently he imported examples of 
the same species from Norway. But although in both cases 
the birds survived for a few years, they never bred, and 
eventually died out, as Capt. Barrett-Hamilton has recorded 
(see 'Irish Nat.^ viii. pp. 41, 43). Col. Cooper was equally 
unsuccessful with similar attempts to introduce into Ireland 
Capercailzies, Beeves's Pheasants, Hawfinches, and other 
birds. 
John Wingfield, first Baron Malcolm of Poltalloch, 
who died on the 6th of March last, was born in 1833, 
and educated at Eton and Christ Church, Oxford. He was 
Lieut. -Col. commanding the Argyll and Sutherland High- 
landers Volunteer Battalion, and M.P. for Argyllshire from 
1886-1892. Lord Malcolm was elected to the B.O.U. in
