pays où ils se trouveront. On peut encore faire usage du Zodiaque, publié par Lemonnier (à Paris chez Dezauche): en y suivant la route de la lune, au moyen de ses longitudes et latitudes, et ayant égard à l'effet de la parallaxe, on trouvera à très-peu près le tems des occultations qui pourront avoir lieu." P. 207.-Is any such zodiac published in England? On p. 206, they mention a parallactic machine for giving the point or place of emersion. Where shall I find a description of it? On p. 7, it is erroneously set down that there will be a total eclipse of the moon on the 26th of December, visible at Paris; and no notice is taken of an eclipse of the sun, Jan. 10; another, Dec. 30; nor of one of the moon, Dec. 15; all invisible here. On p. 5, the Julian period is stated as 6530; in the English ephemeris, at 6528: and the apparent obliquity of the ecliptic, Oct. 1, according to Delambre's new tables, = 23° 27′ 43.3": the seconds in the English are 49.3"! In a meteorological journal for 1810, given at p. 214, the magnetic needle was 22° 16' on the 13th March, at the imperial observatory of Paris. This number contains copious tables of the longitudes and latitudes of places, and of the R. A. and declinations of stars. I am, Sir, your obliged servant, SIR, IX. Weather in Iceland during 1814. (To Dr. Thomson.) A. M. As it may not perhaps be uninteresting to some of your readers to know the general state of the weather in Iceland during the past year, I beg leave to subjoin an extract of a letter on that subject, which I lately received from Mr. Magnus Stephenson, Chief Justice in that island, dated Réchiavig, July 26, 1815. I am, Sir, respectfully, your most obedient servant, Liverpool, Aug. 16, 1815. D. G. "A remarkably fine summer (1814) was succeeded by a very stormy autumn, attended with much rain and raw weather. From the beginning of October to the end of December followed much snow and sharp frost, the stormy state of the weather still continuing. From thence to the middle of March succeeded very fine mild weather, without frost; yet often so windy that the fishing could not begin during all that period. Afterwards the weather became calm and agreeable, which continued; and we have scarcely had any frost in 1815 here in the south and the eastern parts of the island; but in the northern part, the winter being milder from September to January, afterwards changed to very stormy, with snow. It continued thus until far in the spring; the consequence of which has been a great loss of sheep in the north country, where the grass came late, and was very scarce every where: besides which it was in some parishes eaten quite away by a caterpillar last spring, which was exceedingly cold, although no drift ice has appeared this year on the northern coast." XI. Temperature of the Atlantic. The following table is given by Humboldt from observations made by him of the temperature of the Atlantic Ocean during his voyage to South America:: Temperature of the Surface of the Sea. 59° Professor John, in order to obtain iodine, burnt four ounces of the fucus vesiculosus: the white ash remaining weighed 4 drams. He found in it manganese and magnesia, but did not succeed in obtaining from it any iodine. This was chiefly owing to the small quantity of ash on which the experiment was made, and partly also to the imperfect method which he followed; for he seems to have been in possession of no other directions except those contained in Davy's first paper on iodine, and they are quite inaccurate. XIII. Animal Concretion. Professor John has lately examined a concretion from the uterus of a woman. From the description which he has given of it, there is reason to consider it as precisely similar to a concretion from the vagina, which I described and analyzed in a preceding volume of the Annals of Philosophy. Accordingly Dr. John found its composition quite analogous. It was composed of phosphate of lime and an animal membranous matter. He detected in it, likewise, traces of carbonate of lime and of muriatic acid. XIV. Saliva. I have lately had an opportunity of making some experiments on saliva, thrown out of the system during a mercurial salivation. The following is the result. Saliva, when first emitted, is an opal liquid, which speedily lets fall a white matter, and then becomes transparent. The white matter thus deposited possesses the characters of coagulated albumen. As mercury is known to act very powerfully as a precipitant of albumen, I thought it possible that in the present case it might have been thrown down by the mercury with which the system was known to be loaded. But I did not succeed in detecting the presence of any of that metal. The specific gravity of the saliva at 60° was 1.0038. It was a ropy liquid, and could be drawn out into fine threads; yet it could not be employed to paste together pieces of paper, not having the property of a cement, This liquid was not altered by prussiate of potash nor infusion of nutgalls. With nitrate of lead it deposited a copious white coagulum. It precipitated likewise with nitrate of mercury. 1050 grs, of it, being evaporated to dryness, left a residue of 7.5 grs. This residue was composed of JOHN TAYLOR, Stratford, Essex, manufacturing chemist; for certain methods of purifying or refining sugar. June 22, 1815. CHARLES SYLVESTER, Derby, engineer; for various improvements in the texture of bobbin lace. June 22, 1815.
