The Vaccination Question Reconsidered. [November, 
of organic chemism, it would need to be far less in quantity 
than that of the sun, of whose total radiations to the earth 
only a minute fraction is thus employed. It seems quite 
possible, then, that organic life may exist elsewhere under 
conditions strikingly unlike those existing upon the earth, 
and may continue to exist and develop through great changes 
in the future conditions of matter. 
Throughout this paper I have confined myself to the 
probable results in the case of attraction being the only force 
aCting upon matter, or to the contingency of the material 
contents of some extensive region of space being enabled to 
display all the possible results of gravitation, without reverse 
influence from without. But if, as argued in my paper in 
the “ Journal” of November, 1880, the amount of repulsive 
energy in matter just equals that of attractive energy, a 
reversal of all these changes must eventually occur, and 
every spheral condensation of matter be sometime succeeded 
by a nebular rarefaction of the same matter. 
III. THE VACCINATION QUESTION RECON- 
SIDERED* 
E have exceedingly little sympathy with “ move- 
ments,” agitations, and societies for the abolition 
of this, that, or the other. Nor do we share Mr. 
Taylor’s touching faith in “the common sense of our 
countrymen,” or in “the force of truth when not suppressed,” 
We hold that no people are so readily led astray by sophists 
and rhetoricians as are the English. At the same time we 
must avow ourselves agreeably disappointed with Mr. 
Taylor’s pamphlet. Instead of sensational appeals to the 
emotions and prejudices of the ignorant, and of any mis- 
representation of opponents, we find sober reasoning, 
candour, and courtesy greater than is sometimes shown by
