periments on spray for the production of ozone. Now, I 
shall show that the writer on ozone in “ Chambers’s Journal” 
knew, or if he did not it was his own fault, that Mr. Baxen- 
dell made known these results before either of the articles 
in the Journal appeared. These results were made known 
and widely circulated in October, 1875 ; and yet, not till 
March, 1877, this writer asserts that “ It had been noticed 
that ozone was developed by the spray of water when under 
pressure.” It had been noticed ! By whom was it noticed, 
and when ? The article reads as if it had just been noticed 
by Signor Bellucci, for we are told that he “ was thereby 
induced to make observations at the Falls of Terni to ascer- 
tain if ozone was produced by the natural pulverisation 
of the water, especially as he had often noticed there the 
characteristic odour of ozone.” It seems very strange, if 
we are to understand that Signor Bellucci had noticed 
that ozone was developed by the spray of water,” and yet 
he was thereby induced to make observations to ascertain 
if ozone was so produced. This is certainly the strangest 
jumble of words I ever read. Why make observations of 
what he had noticed, and if he did not notice the fact, who 
did ? Then again we are told, as if Signor Bellucci had 
originated the idea — “ It is noteworthy that the air over the 
surface of the ocean is richer in ozone than that collected 
on land.” We are left in the dark as to how this has been 
inferred or ascertained ; yet, for further reasons I shall give, 
there can be but little doubt that the writer of this quota- 
tion had the opportunity of learning that in October, 1875, 
Mr. Baxendell wrote from experimental inference “that 
water exposed to the air has the power of condensing oxygen 
upon its surface into a thin film of ozone.” 
I pass now to still more astonishing statements about 
ozone in this journal. I have observed that in Februajy, 
1876, Mr. Dancer read a paper on ozone. This paper is 
printed in the Proceedings of the Society. At the head of
