t iat I have found likcwife among the Obfervations 
of other Stars, that arc not here recited, may be 
owing to inch a Caufe* which, altho’ it fliould not 
ha\e any large Share of Influence, may yet, in cer- 
tain Circumllances, difeover a Defect in a Hypothe- 
hs, that pays no Regard at all to It. But whether 
tnefe Differences do arife from the Caufc already 
hinted at j or whether they proceed from any De- 
fect of the Hypothecs itfcJf in any other refpect ,• it 
wnl not be very material in point of Practice j fmee 
a f } pot hefts, as it was before laid down, appears 
to be fuftcient to folvc all the Thanomena, to as 
^.rcat a ^cgice of Exactnefs, as we can in general 
hope or expect to make Obfervations. For if I take 
me mean of all the Numbers in the laft Column of 
the following Table for „ Urfe Majons, and com- 
pare it with, any one of 164 Obfervations that were 
tasen of it, the Difference will not exceed three 
oeconds.
