François Huber was a remarkable man, who although suffering from an illness that was gradually turning him blind, devoted his life to studying the life cycles of honey bees, using the scientific methods of close observation (often by proxy) and experimentation. His methods and results were recorded in a series of letters to the noted naturalist Charles Bonnet, later published in book form in Switzerland in 1792 and translated into English in 1806. This is a carefully hand-edited version of that book, which includes the analytical index, and the four black-and-white illustrations, moved from a single plate to the relevant places in the text for the reader"s convenience.
