£02 SOME ACCOUNT OF THE 



have only a few remarks to offer, in addition to the acw 

 count delivered by thole gentlemen. 



I. A. (of Sir Robert Barker s plate) is the Semratr 

 yunter, defcribed Dchly obfervatory, No. I. and Oujein 

 obfervatory. No. VI. The arcs on each iide are car- 

 ried as far 'as ninety-iix degrees, which are fubdivided 

 into tenth parts. Each fpace of fix degrees is num- 

 bered from the bottom of the arc towards the top, 

 fixteen in each arc. Each of thefe is equal to twenty- 

 four minutes of our time, which anfwers to the Hindu 

 agronomical gjmrry. Befides the iiair contained in 

 the gnomon, one afcends along a limb of each arc. 

 The dimensions have been given by Mr. Williams, 

 with an accuracy that leaves me nothing to add on 

 that head. With refpec~t to the reafon of the name I 

 am fomewhat in doubt. It may have been given from 

 its eminent utility ; but the Rajah had conferred on 

 one of his principal Pandits the title of Semrat or 

 Prince ; and perhaps this instrument, as well as the 

 Semrat-fiddhanta, may have been denominated in com- 

 pliment to him ; as another instrument (which I have 

 not been able to find out) was called Jey-pergas in al- 

 lulion to the Rajah's name, 



B is the equinoctial dial or Naree-ivila of No. V. 

 Oujein obfervatory. The name given by the Pandits 

 to Mr. Williams (gentu-rage) probably ought to be 

 junter or \unler-raj, q. d. the royal dial. 



C is a circle of iron, faced with brafs, placed be- 

 tween two hone pillars, about the height of the eyes, 

 and revolving round one of its diameters, which is 

 fixed parallel to the axis of the world. The breadth 

 of the rim of the circle is two inches, the thicknefs of 

 iron one inch, of bra Is three tenths of an inch. The 

 diameter mentioned before is not the fame breadth,
