202 EARL DE GREY'S ADDRESS— EUROPE. [May 28, 1860. 



Of the west coast of Italy, the survey has reached the Bay of 

 Salerno ; charts have been published as far as the mouth of the 

 Tiber : several sheets are far advanced in the hands of the 

 engravers, which will appear in the course of the present year, 

 and will include the Ponza Islands and the Straits of Messina. 



The coast extending from near Amalfi, in the Bay of Salerno, 

 to Monteleone in Calabria, has not been examined. For other 

 accounts of the proceedings of French geographers I must refer you 

 to the very full statement contained in the excellent report of our 

 sister Institution, the Geographical Society of Paris. 



We have also received 56 charts published by the Depot de la 

 Marine, which have been incorporated in that valuable series. 



Sardinia. — Three sheets of the large map of Sardinia have been 

 added to our collections during the past year, making 78 sheets 

 already published out of 91, of which the map is to consist. 



Switzerland. — The Great Federal Map, as we are informed by our 

 learned associate. Professor Paul Chaix, of Geneva, commenced 

 about the close of the last century (1791) by Trelles of Berne, 

 is nearly complete.* It is engraved on 25 sheets; the scale is 

 To-o-'ro-j or 1* iiich to a mile. 



Teer, the astronomer of Ziirich, assisted by M. Sistalozzi and 

 Professor Trechsel, conducted the survey to the year 1811, 

 measured two base-lines and carried the triangulation over the 

 cantons of Zurich, St. Gall, Appenzell, Thurgau, and the southern 

 cantons. 



In 1822 General Finsler surveyed the districts of Sargans 

 (St. Gall), and conducted the survey until 1832, when it was con- 

 sidered necessary to connect the Swiss triangles with those of other 

 countries, and especially with the Austrian survey. 



In 1833 General Dufour succeeded M. Wurstenberger, and held 

 a conference, at which it was determined that the map should 

 be engraved on 25 sheets, each sheet 70 centimetres long and 48 

 broad, on a scale of xq-o^.Vfo- of nature, corresponding to an area of 

 70,000 metres by 48,000 metres. 



The Government of Lucerne has decided on engraving that 

 canton, on a scale of -ar.o-o-o- or about 2*8 inches to a mile. The 

 Canton of Glarus will be issued in about a year on a scale of 

 TT.oirtrj ^^t I regret to be informed that the Canton of Schaffhausen 

 is not to be published as part of the Federal Map. 



♦ The only sheet wanting (1860) is No. 13, and small portions of Nos. 8, 22, 23.
