14 Letters of Sir Wiit1am Jones to Samurz Darts, Esq. 
observation was probably coarse, as Newton says of Chiron’s: but the dif- 
ficulty to me is to fix precisely the last degree of Révati, or the first of 
Aswint, in the Hindu sphere. Could I depend on the Sédstras, which 
unanimously place the ydga star of Aswint in the 8" deg. of longitude, and 
the 10" of northern latitude, I should pronounce that star to be « Arietis, 
the longitude of which in our sphere was, I believe, on Ist Jan. 1790, 
% 4° 43’ 20’, whence the origin of the Hindu Zodiac would be v 26° 43’ 
20’—but where then shall we find the ydga star of Révai?, to which all the 
tables give no latitude, and most of them no longitude? It cannot be 
€ Piscium, which is more than 17 degrees from « Arietis. In short, I am 
so puzzled by this same ydga star of Révati, that I could not travel with 
comfort round the Zodiac with your table in my hand, and Harris’s chart 
before me. I wish I were at Bhagalpur to take that celestial journey with 
you; but I must, after this day, abandon the stars, and attend for a month 
longer to squabbles in court about gold mohrs and star—pagodas. 
I am, dear Sir, 
Your ever faithful 
& affect: Serv 
W. JONES. 
The following Note by Mr. Davis is appended to the preceding Letter. 
The beginning of Aswinit must be distant in longitude from the present 
place of the vernal equinox 19° 21’ nearly. I say nearly, because there 
seems to be an error in the aynansa of almost a degree. ‘The sun enters 
Aries by our account (which I suppose to be correct) near a day later than 
his arrival at the equinox by the Hindu computation ; and this disagree- 
ment should be considered in determining the beginning of Aswin) on 
Harris’s chart. Of the few yéga stars I have had leasure to compare with 
our Tables, that of Chitra corresponds the nearest: it should be found in 
long. (180° + 19° 21’ =) 199° 21’ and lat. 2° S., and in the Britannic Ca- 
talogue, Spica has long. « 19° 31’ 21” or 199° 81’ 21’, and lat. 2° 1’ 59” 8. 
I am assured by my Pandit that Cretica’s yoga is one of the Pleiades, the 
brightest of which has in the Britannic Catalogue, long. 8 25° 40’ 8’, 
lat. 4° 0’ 37’ N.: here there is a greater difference, for the long. of Cretica’s 
yoga is (37° 30’ + 19° 21’=) 8 26° 51’, and its lat. 5° N., « Arietis cannot 
be the ydga of Bharani, because its long. in our Catalogue is 33° 19’ 18’,
