"For a laboratory microscope, the pattern represented here has been found very convienient, —the framework being of mahogany or other hard wood, the stage being large enough to admit a dissection or carry a water-trough of considerable size, and the bent armthat carries the "powers" being made capable of reversion, so as to permit the use of lenses of very long as well as of very short focus." —The Encyclopedia Britannica, 1903

"Let a be the distance at which an object can be see distinctly, and b, the distance at which the same object is seen through the lens, and supose tthe distance of a from the eye, be twice that of b. Then because the object is at half the distance that it was before, it will appear twice as large...." -Comstock 1850

"This consists of two convex lenses, by one of which the image is formed within the tube of the instrument, and by the other this image is magnified as seen by the eye; so that by this instrument the object itself is not seen, as with the single microscope, bu we see only its magnified image." -Comstock 1850

"A Compound Microscope. The appearance of the various structures and tissues of the human body as revealed by the microscope possesses a curious fascination for every observer, especially for young students. No one ever forgets the first look at a drop of blood, or the circulation of blood in the web of a frog's foot as revealed by the microscope." — Blaisedell, 1904

"The intersection of the principal rays lies in front of the object, and consequently objects in front of the plane focused for will be projected on E magnified and the objects lying behind it diminished ("hypercentric" transmission). It produces a perspective representation entirely opposed to ordinary vision." —Encyclopaedia Britannica, 1910
