Mr. Joun Frower exhibited and described a male Hybrid, 5 
between the Black Grouse (Tetrao tetrix), and the Hazel Grouse 
(Bonasa betulina), which he had purchased at the shop of 
Mr. Smithers, poulterer, Cannon Street, London, on March 16th, 
1876. The Black Grouse has been known to cross with the 
Capireailly, the Willow Grouse, the Common Pheasant, and even 
with the Barn Door Fowl: all of which species are polygamous. 
It has also been known, on one or two occasions, to cross with the 
Red Grouse, which is monogamous, but this is thé only instance on 
record of a hybrid between the Black Grouse and the Hazel Grouse, 
which is also a monogamous species. Judging from the plumage 
this bird seems to’ be the produce of a Hazel Cock, and a Grey Hen. 
Mr. Flower called particular attention to the peculiar structure of 
the bird’s feet, which much resemble those of the Black Grouse, 
and are specially formed to enable the bird to walk with ease 
and comfort over soft and yielding or hard and slippery snow. 
This bird was exhibited at a meeting of the Zoological Society of 
London, on April 4th, and excited much interest. 
At the conclusion of the description, which was listened to 
with much interest, the President expressed the thanks of the Club 
to Mr. Flower, and the meeting was soon afterwards brought to 
~ a close. 
April 26th, 1876.—Extra Meeting held in the Public Hall. The 
President, Henry Lez, Esq., in the chair.

Mr. H. Les, the President, in introducing the Lecturer to the 
audience, said when the Croydon Microscopical Club was 
established, just six years ago, and a preliminary meeting of its 
promoters was held at his house, little more was anticipaied, of it 
than that a few men interested in microscopical science might meet 
together for their mutual pleasure and advantage at each other’s 
residences ; but before they had actually started, so many expressed 
a desire to join the moyement that they had about forty members. 
Their opening meeting was honoured by the presence of many first- 
class men, among whom was the founder of the Microseopical 
Society of London, now the Royal Microscopical Society. They 
started, therefore, with good assistance, and since then, he was 
happy to say, they had made rapid, though sure and steady 
progress; and the Club now numbered nearly 2U0 members. 
(Cheers.) They soon found that the funds at their disposal, 
obtained by small subscriptions from a large number, enabled them -
