44 Analyses of Books . [January, 
degree.” We must confess our inability to accept this argument. 
We fail to see in air and water, which are not individualised, any 
properties which may be fairly interpreted as reproduction. In 
neuter bees, &c., the sexual organs are abortive rather than non- 
existent, as is proved by the fadt that a difference of diet de- 
velops the larva of a working bee into a queen. 
If we assume all matter as living, we are still met with the 
fadt that what we call inorganic matter has never within human 
knowledge been transmuted into even the lowest plant or animal. 
Thus the difficulty of spontaneous generation remains unsolved. 
So far, the work before us may be accepted as an interesting 
and thoughtful continuation of “Life and Habit ” and of “ Evolu- 
tion, Old and New.” But it is interpenetrated with polemical 
and personal matter, which we read with much regret, since, 
whoever may ultimately prove to be in the right, the interests of 
Science can scarcely fail to be compromised. On the grave 
charges here brought against Mr. Darwin it would be unfair to 
decide until both parties have been heard, and we do not see 
that a discussion of the personal charadter of any scientific man 
falls within our jurisdiction. Still we feel free to declare that had 
we, when reviewing Dr. Krause’s work, been aware of the fadts 
now brought forward, our critique would have been somewhat 
modified. If an editor or translator interpolates passages in any 
work, without distindt acknowledgment, he sins both against 
author and reader. If the additions and alterations were made 
by Dr. Krause himself, the public ought to have been told that 
the English version was based, not upon the original text as 
found in “ Kosmos ” for February, 1879, but upon a revised and 
amended issue. 
But leaving Mr. Darwin out of the question, the author is but 
scantily courteous to Mr. Wallace, Prof. Huxley, and naturalists 
in general. We are struck with the following passage : — “From 
ladies (?) and gentlemen of science I admit that I have no expec- 
tations. There is no condudt so dishonourable that people will 
not deny it or explain it away if it has been committed by one 
whom they recognise as of their own persuasion. It must be 
remembered that fadts cannot be respedted by the scientist in the 
same way as by other people. It is his business to familiarise 
himself with fadts, and, as we all know, the path from familiarity 
to contempt is an easy one.” Again : — “ Do not let him (i.e., the 
reader) be too much cast down by the bad language with which 
professional scientists obscure the issue, nor by their seeming to 
make it their business to fog us under the pretext of removing 
our difficulties. It is not the ratcatcher’s business to catch all 
the rats ; and, as Handel observed so sensibly, ‘ every profes- 
sional gentleman must do his best for to live.’ ” 
That these sayings are very clever and very bitter we do not 
dispute. But are they justifiable, and what good purpose are 
they likely to serve ? The denunciations which Mr. Butler,
