Not illustrated. 1802 edition. Excerpt: ... LETTERS ON DIFFERENT SUBJECTS IN PHYSICS AND PHILOSOPHY. m LETTER I. Of Magnitude, or Extension. Madam, THE hope of having the honour to communicate, in person, to your Highness, my lessons in Geometry, becoming more and more distant, which is a very sensible mortisication to me, I feel myself impelled to supply personal instruction by writing, as far as the nature of the objects can permit.
