The obfervations, which I have taken, to ground 
the meafurement on, are thofe of the 16th and 23d 
of September, and of the lft of OClober. It ap- 
pears very evident, not only from this rough calcu- 
lation, but every other circumftance of this comet, 
that it is not the fame with that in the year 1682 : 
which, on certain accounts, is very deftrable to be 
known 3 for both here, and in other parts of the Ne- 
therlands, there have been fome people, who have 
publifhed mere conjectures ; and have ventured (very 
minutely and exaCtly, as they pretended) about the 
time that this comet fir ft made its appearance, to pre- 
dict the return of the comet of the year 1682. But by 
the above, the weaknefs of their pretenlions is very 
evident to all the world : whereas, if this had proved 
to be the expeCted comet, they would have affumed 
to themfelves much undue praife, and have pretended 
to knowlege even fuperior to the every-where much 
celebrated Newton and Halley. 
It appears alfo probable to me, that this comet is 
none c/f thofe already calculated, or brought upon a 
lift, by Meftieurs Halley and Struyk. It is fome what 
remarkable,
