About this period also flourished the great, the illustrious +Linnæus+, whose labours diffused light over every department of natural science, and have justly caused him to be regarded as one of its brightest ornaments. He has generally been considered as the founder of the artificial system of arrangement; but a very near approach to it was made by that brilliant constellation of naturalists whom I have enumerated as having flourished at the close of the 17th century, and who may probably be regarded as having paved the way, and prepared materials, for the formation of his more perfect system. Afterwards appeared the works of the celebrated +Bonnet+ of Geneva, the admiring correspondent of Reaumur, and the patron and friend of Huber. This great physiologist became addicted to the study of entomology before he was seventeen years of age, from reading _Spectacle de la Nature_; and his decisive experiments upon Aphides do him the highest credit. His works are universally admired for their candour and ingenuity, as well as for their manifest tendency to promote the happiness of man, by exciting in him the love of knowledge and virtue. We now come to the physiological discoveries of +Schirach+, +Hunter+ and +Huber+, men who have wonderfully advanced the science of entomology, by a series of experiments most ably conducted, by the most patient investigation, and the most accurate and enlightened observation, and placed it upon the solid foundation of rational induction. Several other writers also, both in systematic works and in periodical publications, have contributed to throw much light upon the œconomy and habits of the bee. Of the latter description in our own country may be enumerated +Arthur Dobbs+, Esq.; +Thomas Andrew Knight+, Esq.; Sir +C. S. Mackenzie+, and the +Rev. W. Dunbar+.
