Internal Enemies .

consider it entitled to a careful examination, both as regards 
its conclusion and the phenomena upon which it is based ; 
the science of odours has yet to be constituted, and we are 
convinced that it will amply repay the needful trouble. 
One of our author’s favourite ideas is that the social split 
between Tews and Christians, between Aryans and Negroes, 
&c., depends on the want of harmony in their specific ema- 
nations. The conflicting odours of races and nations play 
a great part in the history of mankind. 
Ill, internal enemies. 
Ttf&kTE hear from time to time eloquent and perhaps over- 
charged lamentations over the danger to which 
*' c) public health is exposed from the consumption of 
articles of diet sophisticated with unwholesome ingredients. 
But we too often forget that we are liable to greater peril 
from the use of articles which are incapable of adulteration, 
hut which carry in themselves seeds of disease far deadlier 
and more difficult to overcome than the mineral poisons. 
These seeds, or germs of disease, as we have ventured to 
call them, differ widely among themselves. There are on 
the one hand, ferments or poisons— organic no doubt, and in 
all probability organised— which, when introduced into the 
human body, set up morbid and often fatal adtion, such as 
cholera, typhus, typhoid, scarlatina, diphtheria, and many 
other of the ills that flesh is heir to. But concerning the 
nature of these germs we are still very much in the dark. 
We cannot say whether each such disease . springs from a 
distindt class of germs, which, under all circumstances, if 
only swallowed, inhaled, or otherwise introduced into the 
body, produce that disease alone and no other ; or whether 
one and the same kind of germs may not, under different 
conditions, excite affedtions which we classify as distindt. 
Thus doubts are, we believe, entertained by eminent medical 
pradtitioners whether one identical poison may not occasion, 
according to circumstances, either scarlatina or diphtheria. 
There are, on the other hand, organisms which we may 
swallow in our food, of a much larger size, and whose action 
and nature are much better understood, These creatures,
