Observations on the eclipse of the sun, June 16, 1806. 27 
that time by the tables, corrected in longitude and latitude as in the 
above calculations, was 59”°79. The difference between this and 
57°89 is 1"°9, which is nearly the additional correction to be applied 
to the latitude of the moon, making the whole correction —8""7. At 
the southern. place of observation the D’s parallax —9’s parallax in 
longitude was +5’ 14°49, in latitude —18' 49”°10, and the moon’s ap- 
parent semidiameter 16’ 4154. Hence the least apparent distance 
of the centres of the sun and moon, by the tables, corrected as above, 
was 61"0. The apparent difference of their semidiameters, was 59-04. 
The difference of these ‘numbers, 1-96, “being added to 6”-8 gives 
nearly the limit of the error of the. aha i oo A that is,
