It is better, therefore, to have a sheet- iron case (Fig. 260) to contain potato-knives, scalpels and other in- struments, and to ster- ilise them by placing the case in the hot-air steriliser for an hour at 150° 0.

The box can be opened at the side, and each instru- m ent withdrawn with .a pair of sterilised forceps when required for jse Glass Dishes.—Several shallow glass dishes are required for preparing damp chambers for potato-cultivations (Fig. 261). The upper, being the larger, fits •over the lower, and having no handle, admits of these •damp chambers being placed, if necessary, in the incubator in tiers. The large size may also be used in the same way for plate-cultivations. Potato Knives. — A •common broad smooth-bladed knife set in a wooden handle is sold for this purpose. Scalpels.—Half a dozen scalpels, preferably with metal handles, may be kept especially for inoculating sterilised potatoes. Brush.—A common stout nail-brush, or small scrubbing-bruph, is essential for cleansing Fig. -Damp Chamber for Potato- Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Crookshank, Edgar M.
