86 DR GEORGE WILSON ON THE FINITE DIVISIBILITY OF MATTER. 
has not been offered already, will be of service in removing doubtful knowledge. 
In particular, it may save beginners from seeking for a demonstration where none 
is to be found, and from blaming themselves because they cannot acquiesce in a 
conclusion, the truth of which great names have appeared to warrant. I would, 
observe, however, that, although I have employed the words molecule and atom in 
the preceding discussion, it has been for the sake of simplicity and convenience, 
and to meet WoLLASTON on his own ground. Ido not wish to be understood as 
offering any opinion as to the ultimate constitution of matter, except in so far 
as I deny the success of the only attempt which has been made in modern times, 
to establish, by direct observation, the existence of indivisible atoms.
