tissues of susceptible animals exhibit great activity, multiply¬ 
ing rapidly, growing into long threads, and apparently defy, 
mg the action of the phagocytes, u. In the tissue of non- 
susceptible animals, such as white mice, the bacilli show no 
signs of activity; they rapidly die and disappear. There 
seems, however, to be no intervention of leucocytes. 12. In 
rabbits which have been rendered artificially proof against 
poison the bacilli seem to take longer in disappearing. There 
is rapid eoHection of leucocytes, with some exudation. 13. 
I he rapid death of the bacilli in the white mice is probably 
to be referred to an active power of destruction possessed by 
the organism. 14. The slower disappearance in other ani¬ 
mals is to be referred to the action of the leucocytes, which 
appear to play a special role , as described by Metschnikoff un¬ 
der the term of phagocytosis. But, in addition to this, Dr. 
inger considers that the fluid of the tissues themselves plays 
a prominent part in the destruction of the microbes._ Wiener

Low & Co.) Third Edition. 
A poor book, especially if it be on a scientific subject, is 
not apt to reach a third edition. (In light literature it is 
different. That is manufactured for the amusement of people, 
and its readers can usually bear a good deal of amusing. 
Most readers of merely entertaining literature are in the pas¬ 
sive mood, and are mere receivers, and it is easy to receive. 
ut to read a scientific book, as it ought to be read, is to study, 
and studying is labor. And who loves labor?) The two words 
“ third edition,” therefor, imply much—they imply the value 
of the work. They never could find a place, truthfully, on 
the title page of an inferior scientific work. The title of Dr 
Potter’s ably written book defines its character. It is a com-
