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, bas induced her to venture on publishing a short course on Natural Philsophy; 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.
