were observed, by Le Père Cyrat, in the tail of the comet of 1618; by Helvetius, in the tails of the comets of 1652 and 1661; and by Pingré, in the tail of the comet of 1769. Month. and Eur. Mag.

Transparency of the Ocean. Experiments were made during the voyage of Coquille, to ascertain at what depth in the sea an apparatus became invisible, composed of a plank two feet in diameter painted white, and weighted, so that, on descending, it should always remain horizontal. The results varied very much; at Offale, in the island of Waigiou, on the 13th of September, the disc disappeared at the depth of 59 feet, the weather calm and cloudy; on the 14th, the sky became clear, it disappeared at the depth of 75.3 feet; at Port Jackson, on the 12th and 13th of February, it was not visible at more than 38.3 feet in a dead calm; the mean at New Zealand, in April, was 3.28 feet less; at the isles of Ascension, in January, under favorable circumstances, the extreme limits, in eleven experiments, were 28 and 36 feet.

On the Powerful Effect of Burning-Glasses at great Heights. The extreme transparency of the air on high mountains, which hinders the calorific rays, which traverse it, from heating it directly, gives rise to several effects different from those we observe on the surface of the earth. The heat of the ground, for example, which absorbs the solar rays on those summits, is often, as M. Ramond observes, out of all proportion to that of the atmosphere. When these rays, therefore, are collected in the focus of a lens, they have much greater power than when they traverse a thick and less transparent atmosphere. He found that a lens of very small diameter was sufficient to set fire to bodies, which a lens of double the diameter would scarely heat in lower regions. M. Ramond supposes that the temperature of the different colors of the spectrum might be well ascertained on lofty summits.

The memoir of M. Ramond, which contains these two notices, is entitled, On the Meteorology of the Pic du Midi, and was read at the Academy of Sciences, on the 13th of March, 1826. Edin. Jour. of Science.
