Note 20-† — INTRODUCTION.

“If science can really contribute to the happiness of mankind, it must be in this department; the real comfort of the majority of men in this country is sought for at their own fireside; how desirable does it then become to give every inducement to be at home, by directing all the means of philosophy to increase domestic happiness!”—Sylvester’s Philosophy of Domestic Economy, 4to. 1819, p. 17.
