moistened with a drop of glycerin or water, and examined 
with a magnifying power of from 50 to 100 diameters. If 
no Trichina are visible, it is prudent to re-examine after 
moistening the specimen with a single drop of the solution 
of potassa (1 part in 15 parts of water), when the muscular 
fibre becomes transparent, and the Trichina, if present, are 
brought into full view. It is important, in making the exa- 
mination, to select the sections from those parts where 
Trichina most do congregate, — e.g., from the sinewy ends of 
the muscles, especially those of the eyes, the jaws, the 
neck, &c. 
We are well aware that the existence of Trichince and 
other parasites is urged by the Vegetarians as a powerful 
argument against the use of animal food. Strange to say, 
however, like many other reformers, they indulge at times 
in a little inconsistency. They extend to milk an excep- 
tional toleration. Now milk, to the best of our knowledge, 
never contains Trichince, but if drawn from a cow affeCted 
with tuberculosis — no very rare occurrence — it is able, as 
has been experimentally proved, to set up tubercular disease 
in animals by which it is consumed. This dangerous pro- 
perty, moreover, is not in the least removed by boiling. So 
that Vegetarianism, as generally preached and practised, is 
no safeguard. 
IV. THE ANTIQUITY OF MANKIND.* 
HILST the first appearance of human life upon the 
globe has risen almost to the rank of a “ burning 
question,” no small share of its attraction and of 
the attention which it receives are derived, singularly 
enough, from an extraneous and even an illegitimate, 
source. The true man of Science, whilst eager to learn the 
exadt truth on this subject, is utterly indifferent what that 
truth may be. Prove to him that our forefathers have lived 
and suffered and died upon this planet for seven million, or 
merely for some seven thousand years, and he will listen
