Exceptional weather occurred from September 13 to September 20, and appears to have been in connexion with the Alta Vista storm of the 14th, though not in exact coincidence. As this was a period during which the computed barometric altitudes of the mountain station gave very wild results compared with the yacht, we have computed the upper observations again as compared with Orotava; but the discordances are even greater, as the enclosed numbers will show, and they are evidently in connexion with the same general disturbances of the atmosphere, thereby reflecting credit on both the lower observers. Boiling-point Thermometer. A boiling-point thermometer, made by Mr. Adie of Edinburgh, graduated to tenths, and reading to hundredths of a degree, and since admirably tested by my friend Mr. Welsh of the Kew Observatory, was observed with at Guajara, Alta Vista and the Peak, but not so often as I see would have been desirable; so that I can only now state that for approximative purposes Captain Boileau's Tables are most satisfactory, giving by two observations the height of Guajara subject to a correction of +40 feet, Alta Vista +70, and the Peak--26; the corrections of simultaneous barometrical altitudes being +122. +98, and--2 feet. (6.) Peripatetic Observations. In all the journeyings up and down the mountain, the altitudes, were measured by myself with a sympiesometer, especially made for the occasion by Mr. John Adie. From the simultaneous readings of this instrument with the barometer at Orotava, Guajara, and Alta Vista, a temperature and an altitude correction have been made out, and have been applied in every case to reduce the sympiesometer reading to what our barometer, corrected, woidd have shown at the same place and time. The calculation 'of..
