Pronounced by experts, by the highest scientific authorities in such matters, to be the most complete, most perfect, 
most useful, and the cheapest instrument of the kind ever devised in this or any other country. 
Dr. GEORGE R. CUTTER, Translator and Editor of Prof. Heinrich Frey’s great work on the “Microscope and 
Microscopical Technology” and “Compendium of Histology,” Author of the Dictionary of German Medical Terj^s, 
Surgeon to the N. Y. Eye and Ear Infirmary, etc., etc., and one of the recognized living authorities on the Miwo- 
scope, writes us as follows: * 
52 Bedford Ave., Brooklyn, N. Y., August 19, 1884. 
“ I am very much pleased with your NEW AMERICAN AGRICULTURIST MICROSCOPE. I find the lenses very clear 
and well centred. On combining the three lenses with the diaphragm, I get a clear, well-defined, highly magnified 
image. The stand, mirror, stage, and arrangement for adjusting the lenses are capital; and both the defining and 
resolving powers of the combination ARE VERY GREAT. I have used this Microscope for dissecting and preparing 
specimens, and find it equal to some imported ones costing from from fifty to seventy-five francs (that is, from $IO 
to $ I 5 in Paris'. For examining certain specimens, and for many purposes, it is SUPERIOR to MANY COMPOUND 
MICROSCOPES COSTING SEVERAL TIMES THAT SUM. I think the excellence of the instrument, the surprisingly 
low price at which it is sold, and the very Judicious directions for its use which accompany the instrument, are 
destined to largely add to the microscopical talent of the country, by increasing the number of amateur micro- 
scopists.” Respectfully, GEORGE R. CUTTER, M.D. 
By means of the telescope we discovei' unknown 
worlds; but there is an invisible world around us, full of 
objects hidden from our eyes by their minuteness, which, 
by the aid of a microscope, we can discover and study 
with great pleasure and profit to ourselves. There are 
animal forms so infinitesimal that millions of them move, 
feed, and multiply, and apparently enjoy themselves in a 
space as small as a five cent piece. 
Not only are there minute forms of animal life, but 
there are innumerable plants so small that no one is 
aware of their existence until it is revealed by the Micro¬ 
scope. These Little Things are not only interesting, 
but to see and know them is of 
Great Importance to Us. 
The greatest harm to our Crops, our Animals, our 
Fruits, our Flowers, even to our bodies, is found to be

due toliving things, both vegetable and animal, so small 
that they have until recently escaped our knowledge. 
Bo You Want to See some of these small but 
wonderfully interesting things ? Wo are now prepared 
to help every reader of the American Agriculturist to 
some conception of them, to help look a little way down 
into this unseen world.

for the readers of this paper by the renowned Bausch 
& Lomb Optical Co., enables j'ou to examine, and to 
see very distinctly and clearly, a vast multitude of 
interesting things, each one a thousand times smaller 
than the tiniest thing that you can see with the unas¬ 
sisted eyes. This instrument, as you will learn from the 
description, is accessible to all our readers, either with¬ 
out cost, or at a cost far below anything like it was ever 
before offered—at a cost so small that if you knew how 
valuable it is, you would spare no effort toget it imme¬ 
diately. 
Not a Family, not a Teacher, not a School, 
should be without one. Every farmer in the land should 
have one. It would be of more interest to all, and to 
most people more useful, than anything else they could 
buy for many times the cost. 
By special arrangement to have them manufactured on 
a large scale, witli automatic machinery, (which not only 
secures entire uniformity in quality and a perfection far 
beyond former methods, but reduces the cost to a small 
fraction of the former hand manufacture), these most

tion of the object to be examined is provided. At the 
top of the stand is a Glass Stage set in a frame like 
a watch crystal.—Two nickel-plated Si>ring Clips, 
useful instruments are now brought within the easy 
reach of every man, woman, and child. 
BESCRIPTION. — The American Agriculturist 
NEW Simple Microscope is shown in fig. 1, 
ready for packing in its box, while fig. 2 shows the 
lenses raised and ready for use. The stand or body is of 
nickel-plated metal (resembling silver and untarnisha- 
ble). It stands upon a broad bottom. An opening on 
one side admits light within to a 
Circular Mirror, fig. 3; this concentrates and 
throws the light up to the object examined. This 
Mirror is so suspended that it can be turned to any 
angle required by the incoming light from a window, 
or from a lamp at night. This Mirror is of great im¬ 
portance, and is one of the very decided improvements 
upon the former Simple Microscope supplied seven years
