WORMS! WORMS! WORMS! LAFFERE'S WORM POWDERS are the best remedy for worms; they effect a certain cure, are tasteless, and at the same time are perfectly harmless. As a proof of their efficacy the following case, out of many hundreds, is inserted:—Emma Knight, aged eight years, daughter of James and Caroline Knight, Black Torrington, voided the extraordinary number of eighty-six large worms, some of them over twelve inches long, after taking one dose of the above Powders. Price, under six years of age, 6d.; under twelve, 8d.; under eighteen, 10d.; adults, 1s. Postage, one penny extra. Send stamps and state age, to E. H. LAFFERE, Chemist, Hatherleigh, from whom those Powders are only to be obtained. N.B.—No Agents. Source: Trewman's Exeter Flying Post, Or, Plymouth and Cornish Advertiser, Wednesday 21st January 1863.
