Commencement and middle of eclipse before sunrise, end of the eclipse was ob- 

 served as follows: —

Strong undulations of the sun's limb, at 5° altitude, caused a perceptible uncertainty. [M.] 

 Giving the weiglrts 3, 2, 1, to the above observe^ times, the adopted sidereal time at Dorpat is 20''
