Rough-legged Buzzard near Warrington. — 

 At a meeting of the Warrington Field Club held 

 on November ist, Mr. Geo. Mounfield exhibited a 

 fine specimen of the rough-legged buzzard (Archi- 

 butcs lagopus), which was shot on October 26th, 

 at Rixton, near Warrington. This beautiful bird 

 measured fifty-two inches across the wings and is 

 the first of its species recorded in our district. —

Hairworms. — I have read the article upon 

 " Hair-worms and their Hosts," in Science- 

 Gossip (ante p. 211), with much interest, and

Movement. By E. J. Marey, translated by Eric 

 Pritchard, M.A., M.B., B.Ch. 231 pp. 8vo, with

The author of this work, who, by the way, is a 

 member of the Institute and of the Academy of 

 Medicine, Professor at the College of France, and 

 Director of the Physiological Station, is, like 

 Mr. Muybridge of California, a pioneer in the 

 application of instantaneous photography to the 

 study of moving bodies. The study has latterly 

 become so perfect as to have received the name

infer that any note, however small, which may 

 help to elucidate their life history will be accept- 

 able. I have never found them in the Coleoptera, 

 probably because I never thought of looking there 

 for them ; but I have repeatedly found them in the 

 common earwig (Forficula auricular ia), I should think 

 almost to the extent of 15 to 20 per cent., although I 

 have never attempted an actual comparison. On 

 one occasion in last September, I noticed an earwig 

 struggling on the ground, apparently held by its 

 forceps, and upon attempting to lift it up, found it 

 to be held by a hair-worm, part being in the body 

 of the insect and part (about one and-a-half inches) 

 in the ground. By gently pulling the earwig I 

 withdrew the worm from the soil, and it remained 

 hanging from the earwig. The subsoil in this 

 neighbourhood is gravel, and frequently in hard, 

 frosty weather, when trenches four feet deep have 

 been sunk to obtain gravel, I have noticed torpid 

 hair-worms coiled in a tight knot as deep as three 

 feet six inches. The warmth of the hand soon 

 causes them to uncoil and move about. I have 

 invariably found them to follow an earthworm's 

 burrow. — Geo. Parish, 124, Kingston Road, Oxford. 



Chronophotography. It seems only a short time 

 ago that the writer of this notice took the chair at 

 the Savage Club on the occasion, we believe, of the 

 first exhibition in Europe, with the aid of a lantern 

 by Edwerd Muybridge, of his then new study by 

 photography of moving animals. Now, in but a few- 

 years since then, we have an important work on the 

 subject by so clever an author as M. Marey, being 

 the result of his investigations at the Physiological 

 Station, an institution maintained by the Govern- 

 ment of France and the City of Paris. Scientific 

 investigators occupied in research into the habits 

 of birds, insects, and other animals, will find this 

 book invaluable, for it is full of suggestion and 

 practical instruction for carrying out such experi- 

 ments. Mr. Pritchard has been very successful as 

 the translator, the book being concisely arranged 

 and most clearly written. We have to thank Mr. 

 Heinemann for permitting us to reproduce two 

 illustrations from the book. One of these shows the 

 flight of a heron demonstrating the movements of 

 the wings. The metre scale at the right hand 

 lower corner of the picture, makes it possible to 

 estimate the rapidity of flight.
