- W4250641637 abstract "ABSTRACT A Cheap and Portable “Turntray.”—In the “social” use of the microscope, there is, as every microscopist well knows, a great amount of discomfort in having continually to be shifting one’s seat, which is alike troublesome and fatiguing to one’s friends as to one’s self, but this is of minor importance compared with the unfitting the eye for observing, and which, with a binocular, is a far more serious drawback than with the single tube, so that some contrivance to obviate this has become almost a necessity. The revolving table is certainly capable of rendering this changing unnecessary, but the table is not only not without its inconveniences, but it has also the more objectionable item of cost to prevent its coming into general use. Nor does it appear that any efficient substitute for it has yet been brought into favour. What is required is a tray capable of holding one full-sized instrument together, its lamp and condenser so arranged that it maybe passed from the observer to a friend sitting by his side, or to a party of four or five or more in succession. The indispensable essentials for it to possess are, first, efficiency; that is, sufficient solidity and steadiness to prevent vibration, and to move freely without friction or noise; next, cheapness; then comes portability; and last, but not least, it must possess a certain amount of “good looks” to ensure its admission to the drawing-room. These desiderata I have succeeded in combining in what I have styled a “turn tray,” and which has delighted all who have seen it." @default.
