SOLAR ECLIPSE OF MAY 14, 15, 1836. 



385 



P.S. The calculations of the true ecliptic conjunction, as well as of 

 the coefficients of the corrections of semidiameters, c 's lat, and par. 

 have been carefully revised, so that I believe this collection of obser- 

 vations to be useful for determining the errors of the lunar elements. 

 Particularly, I think that the annular observations, where the signs 

 of the moon's apparent latitude change, deserve some attention. 



The weather was not favourable, at Hamburg, for observing the 

 solar eclipse of March 15, 1839, but at Rostock, in latitude 54° 5' 45" N. 

 and longitude 39° 20' east of Paris, it was observed by Professor Karsten.
