178 NATURE NOTES 
The Larva Collector’s Cutde and Calendar, giving the times of the appearance of 
the British Macro- Lepidoptera in all their stages. Printed and published 
by J. & W. Davis, Dartford. Price is. net. 
Its title hardly does justice to this useful publication ; for it gives in 
scientific order the food-plants of the insects and substitutes for them, and 
comprehensive notes on rearing Lepidoptera from ova, larvae and pupx. Run- 
ning, as it does, to ninety pages, and bound in cloth boards, it is certainly cheap 
at a shilling. 
All About Birds. By W. Percival Westell. “Feathers” Publishing Co. 
Price IS. fid. 
Mr. Percival Westell’s title is ambiguous. His book is, no doubt, all about 
birds, and no sane person would expect a book at the price of eighteen pence to 
contain all about birds. Nevertheless, to our taste, this book would be dear at 
any price. We do not demand pure science or merely systematic works ; but 
a hotch-potch of newspaper snippings, good, bad and indifferent, without 
arrangement, table of contents, or index, does not seem to us likely to “ stimulate 
interest” or to further the intelligent study of nature. 
Darwinism and Lamarckism Old and New : Four Lectures. By Frederick 
Wollaston Hutton, F.R.S. Duckworth & Co. Price 3s. fid. net. 
These lectures by one of the earliest students of Darwinism are most sugges- 
tive, closely reasoned and comprehensive ; but let no one be deluded into the 
notion that, because they form a small book in large type, they are a merely elemen- 
tary or “ popular” reJiauffe. They require careful study and will repay it ; for 
it is remarkable how open-minded Captain Hutton has remained during the 
forty years since he greeted the first publication of the “ Origin of Species.” The 
lecture on “Darwinism in Human Affairs” has wide bearings far beyond the 
region of natural history. The volume has as frontispiece a charming helio- 
gravure portrait of Lamarck. 
I^'rom Comte to Benjamin Kidd : the Appeal to Biology or Evolution for LIuman 
Guidance. By Robert Mackintosh, D.D. Macmillan & Co. Price8s.fid.net. 
There is little or no biology in this work. It is confessedly a mainly hostile 
review from an intuitionalist stand-point of all those writers upon ethics from 
Comte onwards who can in any way be spoken of as his followers. The author 
starts with the assumption of “the trustworthiness of the moral consciousness,” 
and devotes needless pains to the not very difficult task of showing that philo- 
sophical writers often contradict not only one another but themselves. The work 
is entirely outside the scope of this magazine, but is one which cannot well be 
disregarded by any who interest themselves in the wider application of biological 
teaching.

NATURAL' HISTORY NOTES AND QUERIES. 
Squirrels. — I find that in the month of June, especially, when squirrels are 
pressed for food, they greedily devour the eggs and young of all kinds of birds. 
I was not aware of this fact till I saw a squirrel eating a thrush on one of my 
garden walks. I soon had evidence of their greed for eggs. I have a number of 
doves, which are quite tame and nest in the shrubbery. One pair had a nest within 
fifty yards of the house, with two eggs. I found a squirrel devouring the eggs. 
Another pair nested in the Clematis montana overhanging the dining-room 
window. One young dove was hatched out, but my gardener found a squirrel in 
the nest with the young bird half eaten. Hitherto I have carefully protected 
squirrels as delightful little creatures, enlivening and adding to the beauty of
