Side 380 - The most accurate in observation, the most philosophical in contemplation, and the most faithful in description, amongst all the botanists of his own, or perhaps any other time.
Side 163 - ... the particle. In a few instances the particle was seen to turn on its longer axis. These motions were such as to satisfy me, after frequently repeated observation, that they arose neither from currents in the fluid, nor from its gradual evaporation, but belonged to the particle itself.
Side 93 - To what extent subterraneous cavities may exist even in common rocks is shown in the limestone caverns of Carniola, some of which contain many hundred thousand cubical feet of air ; and in proportion as the depth of an excavation is greater, so is the air more fit for combustion. The same circumstance which would give alloys of the metals of the earths the power of producing volcanic phenomena, namely...
Side 166 - I never failed to disengage the molecules in sufficient numbers to ascertain their apparent identity in size, form, and motion, with the smaller particles of the grains of pollen. I examined also various products of organic bodies, particularly the gum resins, and substances of vegetable origin, extending my inquiry even to pit-coal ; and in all these bodies molecules were found in abundance. I remark here also, partly as a caution to those who may hereafter engage in the same inquiry, that the dust...
