Agriculturists are, or ought to be, more impressed by the subject of parasites than any other class outside medical and veterinary practitioners, for it is no exaggeration to say that a profit or loss on the year’s working depends on the number of enemies called parasites, from whose depredations they at all times suffer more or less. Salads eaten raw constitute a danger to human beings, as the minute eggs are quite invisible, and no ordinary washing disposes of them. The eating of salt is to a great extent a protection, but it has to be remembered that' while horned stock, sheep and horses benefit in many ways by salt, pigs, dogs and poultry can only deal with very small quantities. An attack of gastritis is easily provoked by salt in pigs, and fowls may die from a teaspoonful dose.
