Σελίδα 52 - The type is large and open ; there is no fine print to annoy ; the cuts are copies of genuine experiments or natural phenomena, and are of fine execution. In fine, by a system of condensation peculiarly his own, the author reduces each branch to the limits of a single term of study, while sacrificing nothing that is essential, and nothing that is usually retained from the study of the larger manuals in common use. Thus the student has rare opportunity to economize his time, or rather to employ that...
Σελίδα 1 - O's, points or dots are introduced instead of the 0's through the rest of the line, to catch the eye, and to indicate that from thence the annexed first two figures of the Logarithm in the second column stand in the next lower line. N'.
Σελίδα 57 - He is more practical, more systematic more accurate, and besides introduces a number of invaluable features which have never before been combined in a German grammar. Among other things, it may be claimed for Professor Worman that he has been 1ht first to introduce, in an American text•book for learning German, a system of analogy and comparison with other languages.

The language is clear, simple, and interesting, and the illustrations bring the subject within the range of home life and daily experience. They give such of the general principles and the prominent facts as a pupil can make familiar as household word* within a single term.
Σελίδα 44 - During all the years in which he has been laboring, he constantly submitted his own theories and those of others to the practical test of the class-room — approving, rejecting, or modifying them as the experience thus obtained might suggest. In this way he has been able to produce an almost perfect series of class-books, in which every department of mathematics has received minute and exhaustive attention.

Σελίδα 108 - All the interior angles of any rectilineal figure, together with four right angles, are equal to twice as many right angles as the figure has sides.
Σελίδα 49 - Brief History of France, By the author of the " Brief United States," with all the attractive features of that popular work (which see), and new ones of its own. It is believed that the history of France has never before been presented in such brief compass, and this is effected without sacrificing one particle of interest. The book reads like a romance, and, while drawing the student by an irresistible fascination to his task, impresses the great outlines indelibly upon the memory, Gilman's First...
