to be expected. If, however, the compiler has suocessfiilly ar- 

 ranged and condensed the scattered researches of various authors, 

 and united the theory of ancient with the practice of modern 

 discoveries, he has perhaps done all that could reasonably be ex- 

 pected." It is but justice to say, that the author has done all 

 this, and done it well. The work is divided into ten sections. 

 The 1st contains preliminary remarks on the nature of the 

 terrestrial globe, its circles, axis, poles ; on latitude, longitude, 

 and the positions of the sphere : the 2d presents preliminary 

 oiiservations on maps and charts. These serve very naturally 

 to introduce the student to the 3d section, in which " the prin- 

 ciples of the orthographic, the stcreographic, and the globular 

 projections of the spliere are fully demonstrated ; and the last 

 of these is investigated in a manner entirely new, to prove its 

 superiority and admirable fitness in the construction of maps. 



"In the 4th section theory descends to practice; and, as 

 certain combinations are proposed to be effected, the projections 

 are handled in the form of problems." The 5th section is de- 

 voted to Mercator's projection ; the origin and properties of the 

 rhumb line occupy the fith ; the/th embraces the meridional, 

 equatorial, and horizontal construction of maps. The principles 

 of developing a spheric surface on a plane are investigated in 

 the Sth section. In the 9th, which unfolds numerous projec- 

 tions of particular maps, the constructions are presented in a po- 

 pular form, and include every thing of essential service in modern 

 practice. In the lOth section is siiown the extensive application 

 of the orthograj^hic projection of the sphere in the construction 

 and use of theAnalemma — an instrument which, with the assist- 

 ance of good maps, will not only solve many curious problems, 

 but life almost equivalent to a terrestrial globe. 



The Appendix contains various methods of drawing large cir- 

 cles and ellipses ; directions for colouring maps ; a catalogue of 

 some of the best ma])s, and general rules and observations for 

 judging of the accuracy of maps. In the notes and illustrations 

 with which the work concludes, varioirs useful historical and cri- 

 tical remarks occur, drawn from numerous sources, some, of 

 which are difficult of access. 



History of the Unwersity and Colleges of Camlridge. 

 By G. Dykr, A.B. Two Volumes, 8vo. 

 We have perused these volumes with much pleasure ; and 

 have no hesitation in saying they are calculated to afford not 

 only amu'^euicnt, but much useful information and instruction. 

 The general subje-^t is not of a nature to demand much room in 

 }i work like ours ; but the Sth and Dth chapters being short, 

 and falling within our plan, we lay them before our readers.
