    Taking the six coldest months, the mean of the liiglicst temperature is 68-53^ the mean of the lowest 57-67° the mean daily range 10-86° and the mean temperature 63-10° In considering a climate, it is of no use to ascertain merely the annual mean temperature. The important points are the monthly mean temperatures and the daily range. The degree of heat must be neither too high nor too low, lest it be enervating or depressing. The daily range must be neither very much nor very little, for the one indicates great dryness and so great a difference of temperature as to constitute a danger, as in Egypt; whilst the other indicates a moist atmosphere, and, if warm, is sultry and oppressive, like Orotava. At Las Palmas the highest temperature of the warmest day in any of the six coldest months did not exceed the highest temperature of the coldest day of the same month by more than 7° so that, so far as the thermometer could indicate, day after day was of a similar agreeable warmth. The mean temperature of Funchal for the same period is 61-89°, for Las Palmas 63-10°, and for Orotava -64-63° so that Las Palmas, according to the thermometer, is a little warmer tJjan Madeira, but it feels colder owing to the refreshing iSTorth-east Trade wind. Orotava is nearly 3° warmer than Madeira, and 1 J° more than^Las^Palmas ; so that so far as temperature is concerned the two'sSst-mentioned places are more desirable. The daily range of temperature of Las Palmas (10-86°) is slightly greater than Madeira (9-6.5°). My observations of the wet and dry bulb thermometer were not regularly taken, so I am only able to say that the percentage of moisture in the air ranged from 54 to 70 per cent., indicating a moderately dry climate. Las Palmas is favoured with a large amoiuit of sunshine. The sun glows with great brilliancy, and pours down its life-giving rays through a sky of the most beautiful azure, making the air so luminous that everything looks bright and cheerful. Indeed, all nature seems to rejoice in the sunny glory of Grand Canary, the most favoured of the Fortunate Islands. The clear, pure, moderately dry air with which the gentle Trade-
