PREFACE
TO
THE SECOND EDITION.
The favourable reception of the first edition of this Treatise, has induced the Translator to revise it carefully, and to add to it a Second Part, containing the elements of Perspective Drawing, to which the First Part is a good introduction.
Questions, also, upon the more important parts of the book are added; and the Translator hopes that this more correct and enlarged edition will meet with the same favour that a liberal publick has bestowed upon its predecessor.
Dec. 1827.
