The blue glass that | use is of

glass on ali sizes OF them, through winch
the sun light could pass without Interrupt
ton.
>. The blue glass that use is of
DARK MAZARINE BLUE COLOR,
is imported from France, where it is made.
The color is derived from preparation of
the metal cobalt, which is fused in the pot
with the ingredients composing the glass.
Its cost in Philadelphia is about four times
the cost of American window-glass Of SINH
lar quality. This difference Of price is
largely due to the duty on its importation
imposed by Congress, as well as to the diff
ference of exchange, etc.
3. "As to the point of the compass, :"
which suppose to mean from what direc-
ton the sunlight and blue light of the firma-
ment should pass through the glass, have
to say that the direction of the magnetic
currents that are evolved is according to
the laws of magnetism to the North or
South Pole: and that they are developed in
greater force when the blue and sun lights
pass through the glass that is
EXPOSED TOWARDS THE SOUTH POLE:
but there are currents of da magnetism
that are perpendicular to the magnetic me-
ridian, and which flow from the east towards
to patients from using eastern and western
as we'll as southern light.
From my observation l have developed
the most electro magnetism when the at
mosphere was clearest and freest from
cloudy or watery vapor, the sun most bril-
liant, and temperature below 80 degrees of
Fahrenheit. The reason of this is obvi-
Gus: In such conditions of cold, dry at
mosphere, with strong. brilliant sun light,
more electricity is evolved than under any
conditions, and there is less conducting
power to carry it off than when the air is
moist and warm; consequently more heat
and magnetism are developed than under
any other circumstances. Patients suffer
ing from any disease should not neglect
the occurrence of these favorable condi
| tons.
T. The best application of the associated
| blue and sun lights is to put the
| GLASSES IN TIE WINDOWS THEMSELVES,
| for then the blue glass receives the unmiti.
gated force of the impact of the six pri
mary rays of light, travelling with the in
conceivable velocity of 1876, 600 miles pei
second of time, which are estopped by it
producing more friction and evolving more
electricity, and, consequently more heat
and magnetism than would be the case i
the velocity of these rays of light was re-
tarded by passing through successive medi;
of transparent or translucent glass of varied
densities, thus reducing the force of thei
impact.
In the cases of windows being glazed will
plate-glass of large dimensions, have re
commended some of my friends to have ont
or two sashes made of the size of their win
dow frames, have them glazed with plain
transparent glass and blue glass, in pane
the sizes of eight by ten inches or ten b,
twelve inches, and either to substitute then
for the sashes containing the plate glas
(Which is the better plan, or to attach then
to the inside of such sashes, and allow tn
sunlight and the blue light to pass through
both sashes into the apartment
You have expressed surprise that TIN
medical men have not
TAKEN HOLD OF THESE DISCOVERIES.
The reasons are obvious: in the frs
place, for the most part medical men ar
not scientists. Science very rarely compen
safes those who pursue it, while the prac
