This is easily done by placing the glass slide under a bell-glass, inverted over a plate of water, so that it is kept continuously in a saturated atmo- sphere. Any suitable object will do to place the slide on ; but the most convenient appliance will be found to be a simple stand or rack (Fig. 9), which can be constructed. Fig. 9.—Stand with slides for the culture of Uredine spores, placed on a plate of water, and covered by a bell-glass. in a few minutes out of two flat pieces of gutta-percha and four glass rods. The gutta-percha which is used for soling boots answers well enough. If two oblong pieces of equal size, say three and a half by four and a half inches (9 X 12 cm.), be taken, and a hole bored at each of the four corners, and through each pair of holes let a glass rod be passed, a very simple stand is made at the cost of a few pence. For the glass rods an old barometer tube, cut into suitable lengths with a file, does well enough. The great advantage of such a stand is, that when the slides are laid across the rods, they touch only at two.
