A HYPO-TRAY.
A tray for hypo may be made by lining a small wooden box with enamel cloth. Have the cloth a little larger than the inside of the box; fit it smoothly, and fold it at the corners, instead of cutting it; turn the edges over and tack in a few places. The cloth for a box 8 by 10 costs only five cents, and will last a long time if rinsed thoroughly each time after using.
