Plate XXXV. 



Map of the Eastern Alps. 



The accompanying geological Map has been constructed chiefly from the observa- 

 tions of Mr. Murchison, during his visits to the Central and Eastern Alps in the 

 years 1828, 1829 and 1830. The leading points elucidated in the memoir having 

 been also examined by Professor Sedgwick in 1829. The portion of the southern 

 flanks of the Alps which includes the districts of Verona, Vicenza, Monte Bolca, 

 and the Euganean hills, is coloured from observation made during an excursion 

 with Mr. Lyell in 1828. The adjoining district of Bassano was afterwards ex- 

 amined by Mr. Murchison alone (see Phil. Mag. and Annals of Philosophy, N. S. 

 1829), who in the same year travelled through the valleys of the Adige and Fassa, 

 and portions of the Southern and Northern Tyrol. 



A very large portion of the Map has necessarily been coloured from the authority of 

 other observers; and in the first rank of merit among these must be mentioned 

 an unpublished geological Map of the Archduchy of Austria by Dr. Boue, pre- 

 sented by him to the Geological Society of London*. 



This map was found to harmonize, in most respects, with the observations of the 

 authors in the same district ; and the points on which they difter from Dr. Bouc, 

 have been detailed in the memoir. Considerable insight into the general struc- 



* M. Boue intends to publish this map, which has recently been returned to him for that pur- 

 pose, by the Council of the Geological Society.
