fiipply, that in every fecond, over and above the 
vacuities that have been filled up with adventitious 
matter, the foregoing number, 104666 xli, have 
been formed that have received no fuch fupply. The 
jhiid matter of the lun f rufhe9 from all fides into- 
thefe, and fills them up to its own level. The fun. 
by this means fhrinks a little, and lofes, once in every 
fecond, fo much of its folid content, as the folid con- 
tents of thefe vacuities amount to. 
I have found that the folid contents of 46656 xxxvr 
fuch vacuities are equal to the fphere of one yard s . 
Therefore the folid contents of 104666 xli fuch 
vacuities, are equal to 2243 35 £ times the fphere of 
one yard. And fo much is the fun’s folid content 
diminifhed every fecond. 
The fphere of the earth is to the fphere of one 
yard, as 27247031 xiv to 1 h . 
Therefore the fphere of the earth is to 224335!': 
times the fphere of one yard as 121456 xi to 1. 
Therefore the fun lofes an earth of its folid con- 
tent in 121456 xi feconds, or 385130000 Egyptian 
years nearly. 
If the fun’s parallax be 9', the folid content of the 
earth is i 3T _ of the folid content of the fun.

Therefore, in 385130000 Egyptian years, the fun 
fhould lofe x i i i - th of his folid content, and con- 
fequently in the fame time the diameter of the fan 
f I fuppofe the fun to be a fluid mafs : by this hypothefis, I 
give the utmoft force to Dr. franklin’s objection; for, the more 
perfedtly the fun is fluid, the more fuddenly will the vacuities 
be filled up.
