To the Editor:
—After reading the article on a finger-guard in The Journal, March 2, p. 628, I submit my device. A No. 10 or a No. 11 veterinary capsule, hardened in a formaldehyd solution, with holes cut as desired to allow ventilation of the finger, makes a very strong, light and transparent finger-guard, capable of being fastened in place by adhesive plaster.
