"The object of the present work is clearly announced in its title. It is to collect within a small compass the instructions of experimental knowledge upon a great variety of subjects which relate to the present interests of man. It contains above five hundred genuine and practical receipts, which have been compiled by the publisher with extreme difficulty and expense. A reference to the list of subjects which the work contains, will show that the publisher's researches have been extensive, while a comparison of the work with others of the same general character evinces patient labour, and cannot fail to give it pre-eminence.
