עמוד 277 - The life which I led at Glasgow was a pleasurable dissipated life in comparison of that which I lead here at Present. I have begun to write a book in order to pass away the time.
עמוד 56 - Lavoisier, as well as of the conclusion drawn from them, that dephlogisticated air is only water deprived of phlogiston ; but at that time so far was M. Lavoisier from thinking any such opinion warranted, that, till he was prevailed upon to repeat the experiment himself, he found some difficulty in believing that nearly the whole of the two airs could be converted into water.
עמוד 224 - ... that insidious and crafty animal, vulgarly called a statesman or politician, whose councils are directed by the momentary fluctuations of affairs.
