AN HOUR WITH A MICROSCOPE.
An Unseen World Around Us-Sights a
High-power Lens Will Afford.

~IAN~O~ ~
=, 81 suppose there was a time
when the general interest in microscopy
was so great as at present" said the
principal microscope-makeri in the cityto
the Herald reporter. 1T will take me six
weeks or two months to fill the orders [
have on hand, and they keep coming in.
Ihaye orders from all parts of the world.
Here is a very fine instrument intended
for Japan; there is another that is 60
ing to London. | have also a number
making for residents of the city. Our
Microscopical Society is in quite a flour
ishing condition, having over II hun
dred members. Quite a number belong
to the London M~icroscOpical Society;
in fact, we have more members of that
society than any other city in the Unit
ed States. There are a few of our
number who may be called professional
microscopes. We also have some very
skillful amateurs. A prominent law
yer, resident of the North Side, has sew
eral very fine instruments, and is very
active. l made an instrument not long
since for a son of Congressman Adams,
and all through the city there are young
people, and old people, too, who are
beginning to learn that there is an un-
seen world around us well worth look
ing at"
"What is the cost of q good instru-
ment?"
"That depends Oh the amount Of work
put on it and the magnifying power.
They range in price from $50 to $500.
A great many persona think that they
must have the highest magnifying power
in order to have the most enjoyment.
That is a great mistake. With a high
power lens you could not take In the
whole of a fy's eye, let alone his port
ly presence. You could not see all of
his proboscis. You could not take in
the vast dimensions of a grain of sand.
For a beginner that is of no use. He
should first see the object In It's entirety
before studying it in detail. Lenses run
In magnifying power all the way from
ten diameters up to ], 800 or 1000. Here
is one that magnified twenty diameters.
Now look at this object" The reporter
adjusted his eye to the instrument and
saw q curious looking insect, yellowlsh
IN color, with two great bulging eyes
and quite Q sharp proboscis. 1t looked
about the size of a wasp, but had six
remarkably long legs and no wings.
"That," said the optician, "is a cat flea.
You can see the whole of it clearly, and
can study It in detail. You q see
what long legs it has. If You could
jump ashigh in proportion toyour body
as it can, you could Jump over the moon
very nearly. Now, look at it through
this seventy-fve power glass. You can
only see a part of it. With o still high
er power You could only see one of the
hairs on its legs, or one of those smaller
deas that Dean Swift speake Of
AS natnralists observe. a fiea
Has siAaIIer heas that On him prey;
AGGsssese have smaller still to bite 'em.
And so proceed, q aluminium.
II show YOU This as an illustration o.
what / mean-that a beginner does no
want high power lenses to commence
with. When it comes to fine and acien
tifc study with q trained eye, then tht
high powers come In. Yes, sir, it takes
D trained eye to do reliable work witt
the microscope. What a Tendall or
Pasteur sees is one thing; what some
DIR. Fiddlerdee-dee sees, or don't see il
quite another. TFihe apparent increas'
in size given to an object is spoken O
In diameters. We say an objec. is mag
nified so raany diameters, meaning ths
Iineal measure across it I'M any direc'
lion. As you see that cat flea through
this Empower lens il is magnifed u
diameters. Al cat flea you can see witt
the naked eye; il is about the same il
size as the human flea. Now, / vii
show you something that the naked ey,
never could have discovered"
The reporter looked and saw wha
appeared TO be dozen pieces Of yer,
slender white cord, each probably hal
an inch long, coiled or tied up in loos
