It appears from these Tables that the summer and winter 
lunations exhibit the same law, there being in both cases two 
maxima and two minima, and their epochs coinciding nearly 
with those already given for the entire year. There is, indeed, 
an apparent difference in the magnitude of the range ; that of 
the summer lunations being 089 when the moon is eastward 
of the meridian, and 1’-04 when westward, while for the winter 
lunations the corresponding ranges are 0'-78 and 060.
