and it is impossible to weave bad cloth
with them. This is large claim, and we
believe about 65 per cent of 1T.
The Iron Age estimates the American
output OF aluminium in 1895 at $780, 900
pounds, and believes that the production
of the present year will reach the impos-
ing total of COCO pounds per day, or over
1000, 600 pounds
Charles d. Mosher, yacht designer, of
New York, is now at work on steam
yacht which Is to have a considerable part
of her interior metal work of aluminium.
The metal will be used in the framing and
fittings, so as to reduce weight as much as
possible. The yacht Is intended to be
flyer, and by using aluminium more weight
can be put into the engine and boilers.
A series of experiments were undertaken
recently i'll Germany to determine which,
if any, OF the ordinary additions TO pastes
and mucilages for bottle labels prevented
fermentation without injuring the ad-
hesive qualities OF the paste. Among the
anti ferments under observation were sali-
cylic acid, boracic acid, thymol, oil of
cloves. etc. Without going into minutie,
it was found that dextrin, impregnated
with from TO 5 per cent of thymol, pro-
duced a paste that has thus far proved
all that could be desired.
Undoubtedly, says Professor Oliver
Lodge in the Electrician, London, the x
rays do not start from the cathode or
from anything attached to the cathode,
/ but do start from a surface on which the
cathode rays strike, whether it be an act
ual anode or only on 'anti-cathodic" sur
face. Best, however, if it be an actual
anode. l suggested the term "anode-
rays" therefore, while Professor S. 2.
/ Thompson prefers the term ''anti-cathodic
rays" but probably the term used by
! Roentgen is still the best at present.
! The Institute Pasteur, Paris, has Just
! published it's report for 1895. The salient
feature OF the statement, says the Medical
| News, appears to be that of 1928 persons
! treated only . succumbed to their injuries.
In the fatal cases the symptoms of rabies
| manifested themselves within fifteen days
after the first incubation; one patient,
however, was seized with rabies during
the course OF the treatment, and has not
been included IN the figures. A table of
statistics contains the figures commence
ing from 1885, showing that of the 2671
persons treated in that year % died, or
mortality of "a per cent, while in 1885, of
the 1923 treated only 2 died, or a mortality
of .13 per cent.
DR.. J. Mount Bleyer has invented an in
strument which he calls a photo-fluoro-
scope. 1t consists essentially of a camera
box or Horoscope with a hinged huor-
escent screen door at the objective end,
which when closed enables the operator
to explore the field before exposing the
sensitive plate. Heretofore Roentgen
photography has been pursued under the
| disadvantage that it was not known until
after the plate was developed whether the
objects to be photographed were advan-
tageously located with regard TO the tube
and screen or not. This new arrangement
will be to Roentgen photography very
much what the ground-glass focusing
screen is to ordinary photography. The
proper focus having been obtained the
sensitive plate is inserted and the exposure
made.
