 But there are occasions in which Theophrastus’ explanations of physical phenomena clearly differ from Aristotle’s. He explains, for instance, the composition of the winds entirely by dry exhalations (frs. 186–194 FHS&amp;G); the sideways motion of the winds by the rotation of the heavens (fr. 186 FHS&amp;G); the saltiness of the sea by dry exhalation from the land being carried down again in the rain (fr. 220 FHS&amp;G); the rainfall and condensation by direct physical pressure rather than by the effect of cooling (fr. 211 FHS&amp;G).
