of tliem Red Admiral, Tortoiseshell, and Peacock — and, in view 
of hatching them, a special house was erected in the Botanical 
Gardens at Battersea Park. About 4,000 were hatched and 
released. The report to the Council published recently shows 
the mournful result. The release of the butterflies made no 
appreciable difference to the numbers already in the park. “ An 
army of hungry sparrows and other birds were soon attracted 
to the spot, and a butterfly hunt of the fiercest kind was 
witnessed. Before two days had passed it was doubtful if a 
score of the hatched butterflies had escaped the hungry 
marauders and other enemies. Some flew from the park only 
to be caught by small boys, who immediately sold their captures 
to interested collectors.” The Council, we are told, will not 
try again. 
Photographic Survey of Surrey. — Nearly a score of 
societies of naturalists, archaeologists and photographers have 
banded themselves together under this title “ to preserve a 
record in permanent photographs of buildings of interest, 
antiquities, scenery, geology, natural history, anthropology, &c., 
and of portraits of notable persons, representations of passing 
events of local or historical importance, &c., and of old records, 
rare books, prints, maps, &c., so as to give a comprehensive 
survey of what is valuable and representative in the County of 
Surrey.” Other counties please copy. 
Lodgings at Selborne. — “ Selbornian ” sends us the 
following : “ It may be convenient and useful to lovers of 
Selborne to know that very comfortable and reasonable lodgings 
may be had in the village of Selborne. Ten days botanising in 
this delightful neighbourhood were made more enjoyable by 
the nice, home-like lodgings the writer was fortunate enough 
to find at the following address : Miss Phillips, Myrtle Cottage, 
Selborne, Hants.”

E should be the last to depreciate field natural history. 
For the observation of distribution, habitats, ecology 
and habits it is indispensable. For the study of 
structure, external or internal, or for the elucidation 
of the systematic relations of forms, it is not so : they can often 
be more conveniently investigated in specimens isolated in 
captivity. For anything of the nature of physiological research
