Notes on entomological boxes

Extract

In Parasitology, Vol. III. p. 486, there is a description by F. M. Howlett of the paraffin boxes in use here for preserving pinned insects. As the description of these boxes is incomplete and not quite correct, it seems desirable to add a description which will enable others to make these boxes. We use teak boxes, of a standard size, well varnished within; when the varnish is dry, a piece of cork carpet cut to fit the box and previously enamelled white above, is laid ready to hand, a mixture of paraffin wax (melting point 136° F.) 80% and flake naphthaline 20% is kept melted and a small quantity is run into the box; the cork carpet is at once put in, and rolled down on the melted mixture which sets and holds it; more of the liquid is then run in, sufficient to cover the cork completely; this sets with an even smooth surface (the box being on a perfectly horizontal surface), and the box is ready when cold. This method has not only been tried but we have nearly 2000 boxes in use and are replacing all our papered boxes. To all who may wish to preserve insects in one place I recommend these boxes, but they are too heavy if one is moving and for that a lighter paraffined box is required.
