Upon this principle, the whole art of performing chemical experiments depends...
Página 21 - The mind, when actuated by such, is ever ready to engage in party feuds : for the men of large influence in communities, avowing on both sides a specious cause, some standing up for the just equality of the popular, others for the fair decorum of the aristocratical government, by artful sounds embarrassed those communities for their own private lucre.

Página 29 - I was apprized of any peculiarity in my vision. I had not, however, attended much to the practical discrimination of colours, owing, in some degree, to what I conceived to be a perplexity in their nomenclature. Since the year 1790, the occasional study of botany obliged me to attend more to colours than before. With respect to colours that were white, yellow, or green. I readily assented to the appropriate term. Blue, purple, pink, and crimson appeared rather less distinguishable; being, according...

It is obvious, that before we pay any attention to the two latter opinions, the causes assigned in the first ought to be proved insufficient by direct experiment.
