The latter subjects are followed out at length as regards both Surveying and As- tronomical ‘Instruments. The value of‘ the work is also increased, by the Tables at the end-—-they are of‘great use to Engineers, Surveyors, and Astrono- mers. , - The portability of the work is a great re- commendation-, and the information added in the American Edition, being suited to the practice of the profession-in this coun- try, it will be found one of the most useful and convenient works that an Engineer can use. = While on this subject, we must remark, in.

' “ Monsieur Chaix a Frenchman by birth; and long a resident of the Island of France, has made a discovery of great interest to Steam Navigation. ‘The boilers of En- gines, as is generally known, are after a short use covered internally with a hard, crust, principally composed of calcareous sub- heat from the furnace, to the water contain- ed in the boilers ; increases the already ho"avy expense of' fuel,.anv.l often causes the formation of fissures and cracks which re- quire costly repairs. M. Chaix hasdisco- vered a means as simple as it is ingenious to prevent the formations of these incrusta. tions. His process has been tested by order of the Navy Commissioners at Toulon on board the Government Steamboat P/rare... stance, which prevent. the transmission of
