or three feet long, with its ends cut squarely off, heat one end 
of the iron and with it reach across the glass to near the nick 
made by the file, hold the hot iron at an angle of about ten de- 
grees on the glass. Soon a crack will run from the nick to the 
hot iron, and will follow the iron as it is slowly drawn along. 
The glass can be cut straight, curved or at right angles. 
For fileing, boring, etc., use one ounce spirits of turpentine, 
one ounce camphor (the alcoholic solution), and two drachms 
of ether; wet the file with the above. To bore a hole in a bot- 
tle or plate of glass dip the end of a three cornered file in the 
solution and with it bore through. It is astonishing to see how 
quickly and nicely this can be done.

EDITORIAL NOTES. 
Tue Bacriius or Hyproppopra.—Strange as it may appear, 
it is a fact that there are intelligent beings who do not believe 
in the value of vaccination. They state that it either does not 
prevent smallpox, or, if preventing it, the dangers of using hu- 
manized virus are so great that it should be discontinued. These 
persons regard Jenner, therefore, as one who brought endless 
misfortune to the human race. So to-day, we find, in a promi- 
nent journal before us, an article on the work of Pasteur by one 
who, in all probability, belongs to the class mentioned above. 
The work of this eminent man is characterized as founded “ on 
untrustworthy experiments and unsound reasoning.” The writer 
says that the so-called results of all these researches deserve to 
be rejected and condemned “in the common interests of hu- 
manity as well as science.” The vigorous and decidedly unfair 
tone of the article inclines to the belief that the author is en- 
tirely unacquainted with the brilliant results obtained by this 
indefatigable worker. When Pasteur first made known to the 
world the results of his researches, all parties were only too 
ready to pay homage to the genius which had given to science 
such a discovery. But how changed is the scene. In the place 
of enthusiasm there is the closest and in some instances the 
bitterest criticisms. The latter all honest workers pass over in 
silent contempt, while Pasteur himself invites the former, and
