time, without any medicine, they all disappeared. As a proof of 
what climate did for me, I will mention that three months after 
my arrival I made an attempt to ascend the Peak, but was obliged 
to return when within a few hundred feet of the top, in consequence 
of my men refusing to go any higher. I do not wish it to be sup- 
posed that the climate will cwre consumption, or where tubercular 
disease has occupied a considerable portion of the lungs, which it 
had not in my case; but its warm, dry, equable temperature, which 
can be obtained throughout the year by varying the altitude, is a 
most powerful remedial agent, and will do more to ward off that 
sad malady than any other part of the world, excepting possibly 
the city of Mendoza, on the eastern foot of the Andes, in the republic 
of Rio de la Plata. A scientific French gentleman who had observed 
the temperature of the Villa de Orotava during some years, informed 
me that his self-registering thermometer had never been below 
12°5C. =54°5F.: during the winter I passed there I never saw 
it below 55:5 F. The following is the mean temperature of Santa 
Cruz, the principal port and town on the south side of the island ; 
San Christobal de la Laguna, the capital, 1,740 feet above the sea ; 
and the upper part of the Villa de Orotava, 1,121 feet above the 
sea.
