I made a second excursion to Pico Ariero, and sketched the 

 extraordinary view, of which I could not get even a gUmpse in my 

 first visit. I did this, not merely from its picturesque nature, but 

 to furnish the geologist with the outline which characterizes 

 these peaks of basalt and tufa, and to record the names of the 

 peaks for futm-e travellers, PL. 8 A. I have also added another 

 sketch, PL. 8 B, which I made at the point where we begin the 

 descent into the Coural (when visited from the Jardin da Serra), 

 for the same reasons. The deeply-inclined ledges of the highest 

 part of Sidrao (which is composed of red tufa with dykes) have 

 a very extraordinary appearance. It bears W. 34° S., Euivo 

 W. 2° S., and the highest point of the Torrinhas, W. 11° N., 

 variation allowed. I descended from Ariero about fifty feet below, 

 .and about 1450 feet south of the summit, to get a reflection 

 of the Torrinhas in the artificial horizon, and in so doing shut out 

 the two highest points ; the third highest subtended an angle of 

 2° 21', which, the horizontal distance from Ariero to the Torrinhas 

 being 750 P. bra9as, or 5490 E. feet, gives about 5670 feet for the 

 height above the sea. The horizontal distance from Ariero 

 to Euivo is 8166 feet. The highest point of Sidrao must be
