The hypothesis of volcanoes in the moon is not modern, 

 and at present it is almost rejected, and the explanation of Dr. 

 Olbers is generally admitted. The spot Aristarchus, is plainly 

 to be seen when the moon is illuminated by the sun, and hence 

 it is natural that it should appear more luminous than the rest 

 of the disc, when it is enlightened only by the earth. As to 

 the variation of extent which is remarked commonly in the 

 spots at the beginning of a lunation, the phenomena of re- 

 fraction, produced by the position of the moon near the hori- 

 zon, are sufficient to explain it without having recourse tp 

 Lunar Volcanoes. Rev. Enc. 



11. Pavia. — Remedy against Hydrophobia. — New ex- 

 periments, prove the efficacy of chlorine in the treatment of 

 Hydrophobia. Dr. Previsali has prescribed it with success^ 

 in several cases in which the symptoms of that frightful mal- 

 ady had already manifested themselves. He administers it 

 in the form of a drink in the dose of a gros or a gros and a 

 half per day, in citron water, or citron syrup. Rev. Enc. 



12. Padua. — The enterprising traveller BelzonI having 

 given to Padua his native place two colo?sal statues of Isis, 

 of Egyptian porphyry, found in the ruins of Thebes, the grate- 

 ful Paduans in placing them in the Sola dello Ragione had a 

 large medal struck in honour of their fellow-citizen, repre- 

 senting on one side the two Egyptian statues, and on the 

 other, bearing an inscription. Idem. 



13. Libraries of St. Petershurgh. — 1 st. the Imperial Li- 

 brary at the hermitage, contains 300,000 volumes. Though 

 already rich in beautiful and rare works, it continues to in- 

 crease in them. Two Librarians are charged with the 

 care of it. 2d. The Library of Zaluski, now imperial. It 

 belonged to the republic of Poland, and was transported in 

 1799 to Petershurgh, where it has been carefully placed in 

 an elegant building. At each stage there is a beautiful ro- 

 tundo, and two lateral halls. It contains like that at the 

 hermitage, 300,000 volumes, among which, are the most 

 valued works of ancient and oriental philosophy. It is 

 preserved with care, and open to the public. 3d. The 

 Library of the Grand Duke Constantine, consisting of about 

 30,000 volumes of diplomacy, history, and the militarv art.
