1. Iconographic Encyclopaedia of Science, Literature and Art, sys- 

 tematically arranged ; by G. Heck. Wilh 500 steel engravings, by ihe 

 most distinguished artists of Germany : the text translated and edited by 

 Spencer F. Baikd, A.M., M.D., Professor of Natural Sciences in Pick- 

 nson College, Carlisle, Pa. Rudolph Garrigue, N. Y., 2 Barclay street. 

 This elaborate work is an illustrated Encyclopaedia of Science and 

 the Arts. The plates are in 4to, and are issued in portfolios of twenty 

 plates, along with about 80 pages of text. The engraving is exquisite 

 ifl style, and each plate is crowded with figures and equivalent to a vol- 

 ume of learning. The first of this series contains nearly 100 distinct 

 figures, and the second over 150, illustrative of various problems in 

 plain and solid geometry. Another is occupied wilh about 65 figures 

 relating to problems in surveying, measuring heights, &c, to leveling, 

 topographical drawing, projection, conic sections, &c, projection of 

 shadows, perspective. The next includes drawings of various mathe- 

 tnatical instruments, elaborately detailed, as the following: Hair com- 

 passes, proportional compasses, beam compasses, triangular compasses, 

 Farey's elliptograph, pantograph, eidograph, parallel ruler and spring 

 compasses, protractor, measuring staff and chain with arrows and 

 pickets, plane table, Thayer's plane table, level, diopier ruler, astrolabe, 

 compass, repeating circle, graphomeler, sextant, leveling instruments. 

 Another plate illustrates in beautiful style the change of the seasons upon 

 the earth, the forms and appearances of comets, different nebulas, Sat- 

 urn and his belt, &e. ; and this is but one of len plates devoted lo astron- 

 omy, among which No. 11 is a very elegant map of the moon's surface, 

 with enlarged drawings, around the margin, of many of the great cra- 

 ters. The same completeness and delicacy of delineation extends to all 



department. 



The text contains a brief statement of the principles of the sciences 

 under consideration, enunciations of problems usually without full 

 demonstrations, descriptions of instruments, and explanations of their 

 modes of use, &c. &c. The translation from the German is by Prof. 

 Baird, of Carlisle, Pennsylvania, a man of accurate learning, and exten- 

 sive knowledge of science. We Jake the following from the Prospec- 

 tus, issued with the first number, the only part yet out. 



The Iconographic Encyclopaedia will embrace (in a series of 500

 trated by pictorial representations, viz: — 



I. Mathematics. II. Natural and Medical Sciences. III. Geogra- 

 phy. IV. Ethnology. V. Military Sciences. VI. Naval Sciences. 

 VII. Architecture. VIII. Mythology, &c. IX. The Fine Arts. X. 

 Technology, with all their respective subdivisions. 



The work will be published in 25 monthly portfolios, each containing 

 20 engravings and eighty pages of letter-press. Price one dollar each 

 part. Subscriptions taken (or the whole work only. ^ 



As the different departments of science, from their varying natures, 

 will demand more or less detailed explanations in letter-press, eighty
