Side 142 - If I have seen farther, it is by standing on the shoulders of giants.
Side 148 - Are not all hypotheses erroneous in which light is supposed to consist in pression or motion propagated through a fluid medium? If it consisted in pression or motion, propagated either in an instant, or in time, it would bend into the shadow.
Side 72 - I am purposing them to be considered of and examined on account of a philosophical discovery, which induced me to the making of the said telescope, and which I doubt not but will prove much more grateful than the communication of that instrument, being, in my judgment, the oddest if not the most considerable detection which hath hitherto been made in the operations of nature.

Side 387 - ... gain by some such trick as turning iron into copper with it than by selling it. 2. Whether, in Hungary, Sclavonia, Bohemia, near the town Eila, or at the mountains of Bohemia near Silesia, there be rivers whose waters are Impregnated with gold ; perhaps, the gold being dissolved by some corrosive waters like aqua regis, and the solution carried along with the streame, that runs through the mines. And whether the practice of laying mercury in the rivers, till it be...
