WHITE S EPHEMERIS. 

 To Richard Taylor, Esq. F.R.A.S. F.L.S. Sfc. 



My Dear Sir, 



I SHALL be very greatly obliged if you will 

 allow me, through the medium of your extensively 

 circulated Magazine, to correct a vexatious blun- 

 der which occurs in White's Ephemeris for 1832, 

 in the first calendar page for August. In the co- 

 lumn of Moon's declination for that month, her 

 longitude is, by a strange mistake, inserted. I en- 

 treat the especial favour of your allowing me to 

 insert the correct column of declination in your 

 valuable publication, as in the margin. 



Also, at p. 42, January column, yor 1 moon in 

 perigee read 1 moon in apogee, ydr 16 moon in 

 apogee 7-ead 16 moon in perigee; and insert, 29 

 moon in apogee. 

 1 am. 



My dear Sir, 



Yours very faithfully, 



Olintiius Gregory.

ON VANADIUM. BY MR. JOHN.STONE. 



" An * Old Correspondent' in the August Number of the Philoso- 

 phical Magazine and Annals, p. 157, mentions my having found 

 vanadium in an ore of lead from Alston Moor, and suggests that it 

 was more probably from the neighbourhood of Keswick. — On this 

 1 have only to remark, that I have never found it, and never said it 

 was to be found in ores of lead, except the two varieties described 

 in the former Number of this Journal, p. 166, as formerly occurring 

 in a now unwrought mine at Wanlockhead." — Edinb. Journ. of 

 Science, Oct. 1831. p. 223.
