structure, that it is the work of one who understands well both the prac- 

 tice and theory of his art. It unites great simplicity of illustration and 

 an exuberance of practical detail, with a clear exhibition of scientific 

 principles. Full directions are given as to the various operations in the 

 field, the uses of instruments, the methods of measurement, calculation, 

 platting and mapping ; and at the same time, demonstrations are freely 

 supplied, so that the faithful student will come forth intelligent as well as 

 skilful. The volume contains a chapter on the Government system of 

 surveying the public lands ; also Traverse Tables, a Table of chords, of 

 sines and cosines, and of tangents and cotangents ; and a map of the 

 United States showing the magnetic variation, displaying to the eye a 

 subject of great importance to the Surveyor. 



18. Annals of the Astronomical Observatory of Harvard College. Vol. 

 I, Part I. cxci pages, 4to. Cambridge, 1856. — The Cambridge Obser- 

 vatory, through funds resulting from the will of Josiah Quincy, Jr., has 

 commenced the printing of its Annals ; and the title-page justly bears 

 tribute to the memory of that Revolutionary patriot. The Observatory is 

 situated in the midst of a generous community, and already the contribu- 

 tions to it, from different sources have amounted to more than 150,000 

 dollars, of which sum, 100,000 dollars were bequeathed by Edward Brom- 

 field Phillips, 10,600 the gift of David Sears, Esq., and 10,000 through the 

 will of Mr. Quincy. This first part of the opening volume is appropriately 

 occupied with a History and Description of the Astronomical Observatory, 

 illustrated by wood-cuts, by William Cranch Bond, A.M., Director of the 

 Observatory. Among the topics, the description and figures of the Electro- 

 recording apparatus are of special interest and importance. The second 

 part which was issued last year, comprises a catalogue of fundamental 

 stars,, and of five thousand five hundred stars down to the eleventh mag- 

 nitude, with some of the twelfth magnitude situated between the parallels 

 of 0° and 0° 20' of north declination.
