A French treatise by Loiseleur-Deslongchamps on growing mulberry trees and raising silkworms in the climate of Paris, including methods for obtaining several silk harvests per year. The first part covers mulberry varieties, planting, and leaf yield; the second covers silkworm rearing, with the author's own experiments, losses, durations, temperatures, and the design of silkworm houses. The third part examines caterpillars other than the silkworm that produce other silks or silky matter, including Chinese wild silkworms, the great peacock moth, North American cocoons, and Bengal cocons brought back by Lamarepicquot.

A French treatise of experimental observations on the silkworm (Bombyx mori) by Loiseleur-Deslongchamps, printed in Paris in 1839. It reports his experiments on egg hatching under cold and varying temperatures, on starving larvae, on feeding them substitutes for mulberry leaves, on moth emergence, mating, egg-laying and egg weight, and on silk thread length. It also covers varieties such as three-molt worms and pedicled cocoons, rearing in the open air, and a critical review of Chinese silk-rearing treatises as translated by Stanislas Julien. It includes tables of hatching and emergence data and one engraved plate of a silkworm on mulberry.
