one at Prague, inferred that there wasa maximum of declination 
two days after the full moon. He also found a maximum cor — 
responding to the greatest northern declination of the moon, 
ut does not appear to have investigated the effect of distance. 
The residuals which we have been treating enable us at once 
to examine these several points.

e effect is very small, scarcely much beyond the probable | 
error; but the table indicates that the north end of the ma is 
deflected to the westward 0’1 at the full and as much to the 
eastward at the day of new moon, the range between full and 
new moon being 02. .A more definite result could hardly be 
expected from a series of observations extending over but five 
ears. 
qZ Treating the effect of the moon’s variation in declination 
precisely the same manner we obtain the following results:
