ON NATURAL PHILOSOPHY, IN WHICH THE ELEMENTS OF THAT SCIENCE ARE FAMILIARLY EXPLAINED, AND ADAPTED TO THE COMPREHENSION OF YOUNG PUPILS. ILLUSTRATED WITH PLATES. BY THE AUTHOR OF CONVERSATIONS ON CHEMISTRY, AND Fourth American Edition. HARTFORD: PRINTED BY GEORGE GOODWIN & SONS. PREFACE. IT is with increased diffidence that the author offers this little work to the public. The encouraging reception which the Conversations on Chemistry, and Political Economy have met with, has induced her to venture on publishing a short course on Natural Philosophy; but not without the greatest apprehensions for its success. Her ignorance of mathematics, and the imperfect knowledge of natural philosophy which that disadvantage necessarily implies, renders her fully sensible of her incompetency to treat the subject in any other way than in the form of a familiar explanation of the first elements, for the use of very young pupils. It is the hope of having done this in a manner that may engage their attention, which encourages her to offer them these additional lessons. They are intended, in a course of elementary science, to precede the Conversations on Chemistry; and were actually written previous to either of her former publications. CONTENTS.
