the anthropoid apes next to man in the scale of creation, but if 
we were to judge animals by their works, the chimpanzee and the 
gorilla must certainly give place to the bee and the ant.” For 
example (p. 11), the larve of certain insects require animal food — 
as soon as they are hatched, and the mother-inse¢ct consequently 
provides them with caterpillar and beetles, by burying them in a 
cell side by side with the unhatched larva. But here a difficulty 
arises: ‘‘if the Cerceris were to kill the beetle before placing it in 
the cell, it would decay, and the young larva, when hatched, would 
only find a mass of corruption. On the other hand, if the beetle 
were buried uninjured, in its struggles to escape it would be 
almost certain to destroy the egg.’ Look then at the wonderful, 
but diabolical, instinct of the creature. ‘‘The wasp has the 
instinét of stinging its prey in the centre of the nervous system, 
thus depriving it of motion, and let us hope of suffering, but not 
of life; consequently, when the young larva leaves the egg, it 
finds ready a sufficient store of wholesome food.” A certain 
species of ants keeps Aphides in bondage, just as we do cows, 
for the sake of the honey-dew which they collect ; a certain kind 
of red ant is indolent, and keeps black ants to do work for it. 
Once more, there is a kind of beetle which is blind and helpless 
usually found in ant’s nests; the ants care for all their wants and 
nurse them tenderly. These things, and much more, of the lives 
of insects are told us in popular language in Sir John’s book, 
which we recommend, not alone to the entomologist, but to the 
general reader. 
Ozone and Antozone: their History and Nature. By C.B. Fox, 
M.D. London: J. and A. Churchill. 
Ir, as Dr. Fox not unjustly remarks, ‘to the philosopher, the 
physician, the meteorologist, and the chemist there is perhaps no 
subject more attractive than that of ozone,” it must be conceded 
that there are few subjects in experimental science more fraught 
with difficulties and involved in doubts. Since Schonbein first 
announced his discovery more than thirty years of research and 
observation have elapsed, yet the very existence of ozone is little 
more than generally conceded. As to the laws of its occurrence 
and distribution, its properties and functions, the means for its 
recognition, and its artificial production, there is a singular 
amount of discrepancy in the results of different observers. 
As to antozone, it is still regarded by many chemists—in 
England at least—as little better than mythological. Such being 
the case, there is evidently room and need for a work like the 
present. Dr. Fox has undertaken the laborious task of giving a 
digest of the most important facts connected with ozone and 
antozone, comparing and, as far as practicable, harmonising, the 
views of former investigators. He endeavours to ‘‘point out the 
circumstances, and the manner in which, and the reason why, 
ozone is observed in the atmosphere,” and finally gives the 
results of his own observations,
