be the rhinoceros, wliich is solitary animal ; besides, Major 

 Latter states that, in the Thibetian manuscript, the rhinoceros 

 is described under the name of servo, and classed with the ele- 

 phant ; " neither," says he, " is it the wild horse (well known 

 in Thibet), for that has also a different name, and is classed in 

 the MS. with the animals which have the hoofs undivided." — 

 " I have written (he subjoined) to the Sachia Lama, requesting 

 him to procure me a perfect skin of the animal, with the head, 

 horn, and hoofs ; but it will be a long time before I can get it 

 down, for they are not to be met with nearer than a month's 

 journey from Lassa." — Quarterly Revieiv. 



ASTRONOMICAL INSTRUMENTS. 



The Chevalier Theodore Carezzini, a Piedmontese, has in- 

 vented two kinds of round tables, which he calls geocentric and 

 heliocentric tables, and by their aid, a person without any know- 

 ledge of mathematics can, in a very short time, thoroughly ob- 

 serve the course of the stars, and explain the celestial phaeno- 

 mena. Ladiec-, and youths, whom the inventor has instructed 

 in his method, have, without much previous knowledge of astro- 

 nomy, solved various problems respecting the sun, the moon, 

 the planets, fixed stars, eclipses, &c. By means of these instru- 

 ments, you may, in the open air, obtain a jmeridian line in a few 

 minutes : and in a journey bv land, never miss the direction to 

 the north. You may also learn the hour during the night, with- 

 out a watch. It is remarkable, that in the country the geocen- 

 tric table may appear in the shape of an astronomical garden, of 

 whatever size you please. It is to be hoped that the inventor 

 of this new method, of which we have given this imperfect no- 

 tice, will be able to overcome all the difficulties which usually op- 

 pose useful inventions of this kind. — From a German Journal. 



ESSENTIAL OIL OF TAR LIGHTS. 



In a considerable district of the town lying on the west side 

 of Tottenham Court Road, a very improved kind of street-lamps 

 have been introduced, which in the whiteness and intensity of 

 their lights, far exceed the street gas lights, under the same 

 bulks of flame ; — each of these lamps being independent, there 

 is no danger of a whole district being left in darkness at once, 

 through an accidental or designed stoppage or destruction of the 

 Gas Main, nor are the inhabitants burlhened bv any expense of 

 service-pipes, and tlie many et celeras of that mode of lighting. 

 On inquiry we have learned, that these lamps have been supplied 

 by the honourable Major Cochrane, under patents to his brother 



Lord
