The observations contained in Mr. Schroeter’s communication, comprise those of Dr. Olbers, made at Bremen, from the 29th of March to the 6th of May, and those of Mr. Bessel at Lilienthal, from the 1st of April to the 11th of May; from which it appears that this planet, now called Vesta, became stationary between the 8th and 11th of May, and is now progressive. Mr. Schroeter endeavoured also to ascertain her magnitude; with magnifying powers of 150 and 300 applied to a 15-feet reflector she seemed equal to a star of the 6th magnitude, but without any appearance of a disc. Mr. Schroeter, and his assistant, both saw the planet at that time with the naked eye.
