Mean Error. h m s s Apparent difference of longitude--2 5 6-58 0028 (x) Personal Equation in giving and receiving signals +-09 + 050 (2) Personal Equation in observing transits +-25 + 079 (3)--2 5 6-24 '098 Notes. (1.) Transit of Venus, 1874. British Observations, p. 283; mean error is deduced from agreement of results on the four different nights. (2.) No satisfactory particulars are published about the determination of the various Personal Equations in giving and receiving signals; it is evident from the remarks (loc. cit., p. 287) that the mean error of the combined equations is certainly not over estimated at + 0-35. (3.) Loc. cit., p. 288; mean error deduced from agreement of results on seven nights. Mokattam--Suez. h m s Apparent difference of longitude--o 5 6 881 + 0066 () Correction for aberration and Personal Equation--'050 +-o8o (B) Notes. (4.) Transit of Venus, 1874. British observations, p. 34S; mean error determined from agreement of the four results. (5.) The determination of the equation, B--H loc. cit., p. 329) is affected with a mean error = + o"o63 in star observing, exclusive of the error io the determination of their personal error in giving and receiving signals.

Determined by Captains Campbell and Heaviside, R.E., on May, 25, 26, 27, 28, 29, 30, 1877. (G.T. Survey of India, Voi. IX., p. (io5)) The accidental mean error of the result is deduced from the agreement of the results on the six nights of...
