He was the author of several performances on vegetable physiology, and the classification of plants; and likewise published numerous works on the materia medica, and chemistry, mineralogy, and every part of natural history. One of the most celebrated is his edition of the “System of Nature of Linnæus.” He, however, is said to have introduced great disorder into the science, by multiplying the species.
