Inquire Within for Anything You Want to Know; or, Over 3,500 Facts for the People.  “Inquire Within” is one of the most valuable and extraordinary volumes ever presented to the American public, and embodies nearly 4,000 facts, in most of which any person living will find instruction, aid and entertainment. As a book to be kept in the family for reference it is unequaled, comprising, as it does, all kinds of books of information in a single volume. _It is a Doctor, a Gardener, a Schoolmaster,_ _A Dancing-Master, an Artist, a Naturalist,_ _A Modeler, a Cook, a Lawyer,_ _A Surgeon, a Chemist, a Perfumer,_ _A Dyer, a Brewer, an Architect,_ _A Bookkeeper, a Confectioner, a Laundress,_ _A  “Hoyle,” a  “Letter-Writer,”_ _A  “Ready Reckoner,” and a Housekeeper._ IT ALSO CONTAINS _Tables of Weights and Measures,_ _Interest Tables from $1 up to $10,000,_ _Innumerable Tables on Curious and Interesting Subjects,_ _All Kinds of Family Amusements and Recreations._ It might strike the casual observer as something incredible, if not impossible, that such an immense and varied amount of matter could be crowded into a book of the merely nominal price of a dollar and a half; but the work contains 436 large pages of small type, closely printed in double column, and a perusal of it will convince the most skeptical that the only thing to be wondered at in it, is the extremely low price at which it is offered. Bound in extra cloth, with gilt side and back. $1.50 The Perfect Gentleman. A book of Etiquette and Eloquence.
