The most important of Jonston's works is his Historia Animalium, which was published at Frankfort on the Maine. The first part, containing five books on fishes and cetacea, and four on the white-blooded aquatic animals, appeared in 1649. The second part, which treats of birds, followed in 1650; the third, on quadrupeds, in 1652; and the fourth, on insects and serpents, in 1653. Several editions of this work have since come out; the latest being that of Heidelberg, in 1755. It is, however, a mere compilation from the writings of Gesner, Aldrovandi, and others. The plates, which are numerous, are also, for the most part, copied from these authors, a few only being original. They are not without merit, having been engraved by the famous Matthew Merian; but several of them, resting on no authority beyond that of simple description, represent objects which have no real existence. His first treatise, which is a collection of the most curious phenomena presented by the sky, the elements, meteors, fossils, plants, birds, quadrupeds, insects, and man, was printed at Amsterdam in 1632, under the title of Thaumatographia Naturalis in Decem Classes Distincta. He also produced a Dendrographia, or natural history of trees and shrubs; and two smaller tracts, the one entitled Notitia Regni Vegetabilis, the other Notitia Regni Mineralis; together with several others, on various subjects, which, as they have long since passed into oblivion, it is unnecessary to mention at greater length. JOHN GOEDART. This distinguished naturalist was born at Middleburg in Holland, in 1620. He was a sedulous observer of the nature and properties of insects, which he examined with admirable patience and sagacity. His work, which was written in Dutch, was published at Middleburg in 1662, with the title Descriptions of the Origin, Species, Qualities, and Metamorphoses of Worms, Caterpillars, &c. Being a painter by profession, he adorned it with very accurate coloured engravings. The treatise was also printed in Latin and French translations. The former bore this title:--Metamorphosis et Historia Naturalis Insectorum, cum Commentario Jo. de Mey et duplici cjusd. Appendice, una de Hemerobiis, altera de Natura Cometarum. An improved edition, in the English language, was published by Lister in 1682; and another, in Latin, in which the species were methodically disposed, appeared in 1685, under the care of the same naturalist, who had the work reprinted a third time as an appendix to his Historia Animalium Angliae. Goedart describes 150 different species, and may be considered as the first who subjected the metamorphoses of insects to accurate examination. He died in 1668. FRANCIS REDI.
