I begin to understand it; but I confess that theidea of insensible heat is so new and strange to me,that it requires some time to render it familiar.

Call it insensible caloric, and the difficulty willappear much less formidable. It is indeed a sortof contradiction to call it heat, when it is so si-tuated as to be incapable of producing that sen-sation.

EMILY.
