Harvard Collection - Slides

Harvard Collection all of our series are mounted on slides, forty by seventy-six millimeters, and we now insist upon the slides being from I.8 to 2 millimetres thick.

The thin slides, which have so long been favorites, are very fragile and often get broken. The thicker slides are much less subject to accident, and have no disadvantages, so far as I know, except that of not permitting the use ofa very short focussed condenser with the microscope. This disadvantage seems to be more theoretical than real. The size of slide adopted was chosen after considerable deliberation, and seems to me, on the whole, to be the most convenient for such series as we have gathered. On this slide we use a standard size of cover-glass, one measuring thirty-five by fifty millimeters. The sections are mounted so as to leave one end free for the label, which is placed as shown in the accompanying figure (Fig.2). On this label the name of the species, direction, and thickness of the sections and their staining are recorded. The label also carries the number of the series and a letter to indicate the position of the slide in the series. This is merely for facilitating the quick arrangement of the slides in cabinets. And finally, the label indicates the numbers ofthe sections, there being recorded for each row of the sections the number of the first and of the last section in that row. This makes it very easy to determine quickly by counting from either end of the row the exact number of any section in the series. In order to have permanent labels we use for writing either Stevens's blue-black writing fluid or Higgins's waterproof ink. I prefer the former.
