CATALOGUE:

Page 1, et seq.: Catalogue of Practical and Scientific Books (etc.): MM is an abbreviation for Messieurs. Abbreviations for technical and professional qualifications, etc. are not always consistently spaced. They have been retained as printed.

Prices for books have been retained, as printed. Those less than $1.00, with a couple of exceptions (50cts,) are printed, e.g. 63, 75, etc., aligned right.

The spelling in the descriptions of books in the Catalogue sometimes depended on whether the author was American or English.

The word 'Price' appears only in the description of one book. It has been retained.
