n8 Mr. Schroeter's new Observations 
though perhaps to others it may not have the same appearance. 
But this very object makes it also my duty to be equally un- 
reserved in remarking what truth is, and demands ; particu- 
larly as evident misunderstanding and error appear to have 
chiefly occasioned those assertions ; which most probably 
would not have been thus made, if the author had then known 
of my very circumstantial memoir,* which was read at the 
jubilee of the university of Erfurt, in a meeting of the Electoral 
Academy of Sciences, and which they ordered to be printed ; 
and could have compared the many careful observations, full 
of matter, contained in it. A copy of this memoir I have lately 
had the honour of communicating to the worthy author of the 
abovementioned paper. 
Therefore, in order to prevent, misapprehensions, let me be 
allowed to make some remarks, which truth requires of me, be- 
fore I communicate faithfully, as I mean to do, my more recent 
observations, which confirm the former ones, and seem to me 
very important. 
l. The celebrated author considers it, with reason, as a 
wonderful relation, that I should profess to have seen appear- 
ances of spherical spots on Saturn, without having, at the same 
time, determined from them the period of his rotation, which 
might have been done in the first hour ; and he thinks that no 
one, who is not possessed of incomparably better sight and te- 
lescopes than he has, can have seen any thing of the kind. In 
that I fully agree with him, and here declare publicly, that I 
have never perceived such an appearance on Saturn, however 
much I wished it.
