and arborescent heaths. The trunks of the last 

 grow to an extraordinary size ; and the flowers 

 with which they are loaded form an agreeable 

 contrast, during a great part of the year, with 

 the hypericum canariense, which is very abun- 

 dant at this height. We stopped to take in our 

 provision of water under a solitary fir-tree. This 

 station is known in the country by the name 

 of Pino del Dornajito ; it's height, according to 

 the barometrical measurement of Mr. de Borda* 

 is 522 toises ; and it commands a magnificent 

 prospect of the sea, and the whole of the nor- 

 thern part of the island. Near Pino del Dor 

 najito, a little on the right of the pathway, is a 

 copious spring of water, into which we plunged 

 the thermometer, which fell to 15*4°. At a hun- 

 dred toises distance from this spring is another 

 equally limpid. If we admit, that these waters 

 indicate nearly the mean heat of the place whence 

 they issue, we find the absolute elevation of the 



* Manuscrit du Depot, Ime cahier, p. 15. I calculated the 

 heights, which I mention in the text, according to the for- 

 mula of Mr. Laplace, and the coefficient of Mr. Ramend. 

 In the manuscript, we find " 516 toises, according to the 

 tables of De Luc." We must not confound the Pino del 

 Dornajito with the station of the Pino de la Merienda, cited 

 by Eden and father Feuillee ; and elevated 800 toises above 

 the level of the ocean. This last station is between the Cara- 

 vela and the Portillo. See the note on the whole of these 

 measures, at the end of the Journal de Route.
