PUJATI has also given us some very good reflexions on this matter, in his Treatise _De la Diéte des Fievreux_, p. 57, &c. Metaphysicians, who appear to have the best handled this point, are Mr. LOCKE, _Essays_, L. ii. c. 32, M. de CONDILLAC, _Traité des animaux_, p. 2. c. 2. and 9. and the anonymous author _des Elemens de Physiologie_, c. 61, 62, 63, 64. I know a man that, having been waked, above twenty years before, at one after midnight, by an alarm of fire, has since that time constantly waked of himself precisely at that hour.

This Work, gathered from his Lessons, from 1730 to 1745, and in that posterior by some years to the Lessons collected by M. DE HALLER, proves that BOERHAAVE had changed his opinion as to the possibility of a purely seminal _gonorrhœa_; and it is well known, that that great man was always ready to renounce his former ideas to adopt new ones, the instant he was convinced of their being the justest.
