Harvard Collection - Embryo Storage

Harvard Collection storing of embryos a convenient method has proved to be the use of a combination of small vials and large jars. A single museum jar is used for one species only,and mislabelled accordingly. The embryos are sorted according to stages, methods of preservation, etc., in cylindrical vials, which have flat bottoms, so that they will stand upright, and straight sides (Fig. 1). The size we have used most measures sixty millimeters in height by twenty millimeters in diameter.

Vials with mouths narrowed are excessively inconvenient. The vials are closed with plugs of absorbent cotton. When necessary a slip of paper, bearing memoranda concerning the specimens in a vial, is put in alongside the plug of cotton, by which it is held in place. The writing on the slip is turned towards the outside of the vial, so that it can be read without displacing it or disturbing the specimens.

Data are written with a lead pencil, but when a more permanent record is desired it is better to use Higgins's waterproof ink. A dozen or more vials may be kept together in a single jar.
