In one case Darwin records that 142 insects were caught by 32 leaves, giving an average of 4'4 insects per leaf. In addition, the small leaves of a Heath and other plant fragments were often blown by the wind on to the leaf accidentally, to which they adhered. He was also able to show that when objects which contain little or no soluble matter come to rest on the leaves, there is no secretion by the glands. But where the substance is nitrogenous, the secretion is copious, and the material absor...bed by the leaf contributes to the food-supply of the plant, and helps to compensate for the limited extent of the root system by which nutriment is derived from the soil. The fact that the leaves of the Butterworts contain a special substance was known for some hundred years before Science discovered its true nature. The ancient herbalist, John Gerarde, wi'iting in 1597, says, " The husbandmen's wives of Yorkshire, do use to annoint the dugs of their kine with the fat and oilous juice of the herbe Butterwoort, when they are bitten with any venemous worm, or chapped, risted, and hurt by any other meanes." Kerner also states that a similar use of this plant is made in Switzerland.
