The following was extracted from the Price and Illustrated Catalogue of Optical Instruments, James W. Queen & Co., 1889.

Queen household microscopes

3061. QUEEN’S UNIVERSAL HOUSEHOLD MICROSCOPE, . . . . . $4.75

This admirable instrument is the most complete, convenient, and powerful Microscope ever produced for so low a cost. It has all the important parts of a first-class instrument, is readily adjusted for the examination of all classes of objects, and is well calculated not only to amuse but instruct young persons, and thereby foster a taste for the study of Natural History.

The Stand is ten inches in height, with hinged joint, allowing it to be inclined to any angle for convenience of observation. The base is of cast-iron, handsomely bronzed, the compound body of finely lacquered brass, with draw-tube for increasing the power of the object-glasses. These are two in number, and give, in connection with the draw-tube, a range of powers from 20 to 100 diameters, or from 400 to 10,000 times. The stage is of ample size, and is provided with spring clips for holding the object whilst under observation; beneath is a concave mirror, conveniently jointed, for the illumination of all transparent objects. All the ordinary animalculæ found in pond-water can be satisfactorily shown with this Microscope. One prepared object, two glass slips, and a pair of brass forceps, are furnished with it, and the whole is packed in a neat and strong walnut wood case.

3062. QUEEN’S UNIVERSAL HOUSEHOLD MICROSCOPE, the same as 3061. with the addition of an Achromatic object-glass of three powers (from 40 to 200 diameters), will exhibit satisfactorily blood and pus corpuscles, . . . . .$8.00

3063. QUEEN’S UNIVERSAL HOUSEHOLD MICROSCOPE, similar to 3061, with additions of Rack and Pinion for adjustment of focus, and a condensing lens for the illumination of opaque objects. These additions render this instrument as near perfect as possible, for so small a cost, and leave but little to be desired. One prepared object, two glass slips, and a pair of brass forceps, accompany each ode, and the whole is contained in a neat polished mahogany case, . . . . . $7.50

3064. QUEEN’S UNIVERSAL HOUSEHOLD MICROSCOPE, same as 3063, with addition of an Achromatic triplet object-glass, giving powers from 40 to 290 diameters, . . . . . . . . . . . . $11.00

We believe these Microscopes — from 3061 to 3064 — cover the entire field possible for such cheap instruments, and that in all essentials they are far in advance of anything heretofore offered the public. In the ten years that have elapsed since we first introduced No. 3061, we have sold several thousands of the same, and always with satisfaction to the purchasers.
