306 Bibliography. 



we may hope that similar observations will soon be extended along its 

 whole outline. The investigations here detailed were made about the 

 Nantucket shoals and Long Island. The author exhibits in a strong 

 light the action of the tides in the accumulation of the loose material 

 constituting shoals, and in determining their positions and outline. 



8. Sixty-second Annual Report of the Regents of the University 

 of the State of New York; made to the Legislature, March 1, 1849. 

 392 pp. 8vo. Albany. 1849. — This Report, besides its fund of informa- 

 tion relating to education in New York, contains, as heretofore, mete- 

 orological tables for the year, made throughout the state and various 

 observations on different atmospheric phenomena. There are also 

 some pages devoted to topographical and other information relating to 

 portions of the state and even to other states, a part of which are val- 

 uable, and another part add nothing to the reputation of the Report. 



9. Reports, etc., of the Smithsonian Institution, exhibiting its Plans, 

 Operations and Financial Condition up to January 1, 1849. From 

 the third Annual Report of the Board of Regents : Presented to 

 Congress, Feb, 19, 1849. 72 pp. 8vo. Washington. 1849.— The ob- 

 jects and plan of the Smithsonian Institution have been noticed at 

 length in a former number of this Journal. It is gratifying to learn 

 that these plans, so noble and comprehensive, are in process of accom- 

 plishment under the supervision of its learned Secretary, Prof. Henry. 



10. A collection of Tables and Formula useful in Geodesy and Prac- 

 tical Astronomy, including Elements for the Projection of Maps ; pre- 

 pared by order of the Topographical Bureau for the use of the Corps 

 of Topographical Engineers; by Capt. T. J. Lee, Topographical En- 

 gineer. 96 pp. 8vo. Washington. 1849. No. 3 of Papers relating to 

 the duties of the Corps of Topographical Engineers. — The Topograph- 

 ical Bureau of our Government, under the general direction of Col. 

 J. J. Abert, is conferring a great benefit on the science of the country, 

 by its recent publications. The work before us has more interest than 

 pertains to a manual for Engineers: its utility will be appreciated by 

 a wide range of readers. It presents in a perspicuous manner the va- 

 rious trigonometrical expressions, formulas and series used in calcula- 

 tions, commencing with the most simple ; embracing equations for the 

 circumference and arcs of circles — and for sides and surfaces of trian- 

 gles : — next explains fully the standards of weights and measures, giv- 

 ing many tables, including long comparative tables of English and 

 French measures, &c. : then passes to Expressions for Surfaces and 

 Contents of Solids of various kinds — Formulas in Hydrometry — Expres- 

 sions for Arithmetical and Geometrical progression — Force of Gravity 



Tables and Formulas in Geodesy, drawn out with the fullness of 

 detail required in the most thorough surveys, with extended tables for 

 the various corrections, as of temperature, the earth's ellipticity, &c. 

 Tables of Corrections for Refraction in Trigonometrical altitudes — Ta- 

 ble of Slopes for given ratio of altitude — Full rules for Barometrical 

 determination of Heights, with several tables for corrections, and oth- 

 ers for the comparison of different thermometers, and for French and 

 English barometers — Rules for the Thermometrical Measurement of 

 Heights — Formula for projection of Maps, with a number of valuable 

 tables— Table of the lengths, in Nautical and Statute miles, of degrees
