FI. Of a Neiv Comet. 



[anno 1793. 



By the Rev. Edward Gregory, M. A., Rector of han- 

 gar, Nottinghamshire, p. 30. 



This comet Mr. G. discovered in the evening of Jan. 8, \7Q3. It was of a 

 dull hazy appearance ; its shape rather oval ; a faint appearance of a tail; but 

 no perceptible nucleus. It passed over the meridian under the pole at 4*' S'" 43^ 

 sidereal time, its zenith distance being 75° 16' \6". The latitude of the place is 

 52° 54' 37", and its longitude 3'" 47^ in time west of Greenwich. 



FlI. Observations of the Comet of 1793, made by the Rev. Nevil Maskelyne, 

 D.D., F.R.S., &€., and other Observers, p. 55.

These places of the comet may admit of some little change, when the stars 

 with which it was compared have been settled by observations with the meridian 

 instruments. 



F'JIf. On the Method of Making Ice at Benares. By John Lloyd Jniliams, Esq., 



of Benares, p. 56. 

 The method of making ice at Seerore, near Benares, is as follows. A space 

 of ground of about 4 acres, nearly level, is divided into square plats, from 4 to 

 5 feet wide. The borders are raised, by earth taken from the surface of the 

 plats, to about 4 inches ; the cavities are filled up with dry straw, or sugar-cane 

 haum, laid smooth, on which are placed as many broad shallow pans, of un- 

 glazed earth, as the spaces will hold. These pans are so extremely porous, that 

 their outsides become moist the instant water is put into them ; they are smeared 

 with butter on the inside, to prevent the ice from adhering to them, and this it 

 is necessary to repeat every 3 or 4 days ; it would otherwise be impossible to 

 remove the ice without either breaking the vessel, or spending more time in 

 effecting it than could be afforded, where so much is to be done in so short a 

 time. In the afternoon these pans are all filled with water, by persons who walk
