Ornithologists ' Club. 
made by Woodpeckers, and were readily accepted by birds, 
especially by Tits. They must, however, be put np properly, 
and in Berlepsch's book on bird-protection some good instruc¬ 
tions were given. Mr. Charles Rothschild and Mr. Walter 
Rothschild had introduced them on a small scale in various 
places, and Mr. Hartert hoped to be able to report concerning 
their success during the next session of the Club, and he 
trusted that other ornithologists would advocate them. They 
could be had for about sixpence each, from a firm in West¬ 
phalia, who were making them according to Berlepsch's 
instructions. 
Mr. Ernst Hartert exhibited and explained an instru¬ 
ment invented by Mr. L. Wiglesworth, which he called a 
Ratiometer/’ the object of which was to ascertain the pro¬ 
portions that different-sized specimens (or parts of specimens) 
bear one to another. Mr. Hartert also announced that 
Mr. Wiglesworth was experimenting with some other instru¬ 
ments likely to be of use in measuring animals. Mr. Hartert 
also read some notes by Mr. L. Wiglesworth (who was not 
able to be present) about the question “ How a Bird-skin 
should be measured.” 
Mr. Heatley Noble exhibited a pair of eggs of the 
Spine-tailed Swift from Nerochinski, and also the nest, eggs, 
and nestling birds of White's Thrush (Oreocichla varia), 
which had been obtained from Mt. Fuji Yama, in Japan, 
by Mr. Alan Owston. He considered that these eggs were 
undoubtedly authentic, and they closely resembled those of 
the Himalayan 0. dauma ; whereas the nest and eggs obtained 
by the late Consul Swinhoe, and supposed by him to have 
been those of White's Thrush, probably belonged to Merula 
mandarina . 
Mr. Walter Goodfellow described a new species of 
Humming-bird, discovered by himself and Mr. Claud 
Hamilton during their recent travels in Ecuador;—
