I have a few remarks respecting the large amount of 
ozone I now detect over the quantity I detected at my 
former station. My present station is only 27 feet higher 
than my former, and about one-third of a mile farther north. 
I was before about one-tliird of a mile from the most popu- 
lous part of the village. I am now nearly two-thirds of a 
mile from it. I have used similar test-papers at both 
stations. I make my own tests, and have used those which 
were made at the same time at both stations. The average 
amount I used to detect at my former station from August 
to December, was — 079 on the scale of comparison. Last 
year from August to December, the amount was — 2*40 on 
the scale. Previous to my removal I tried a test-paper at 
each station. I found each comparison average a similar 
difference. The amount detected by Mr. Vernon, at Old 
Trafford, was usually a little in excess of mine for the 
months named ; but the last year shows a very different 
result. The average amount detected by Mr. Vernon from 
August to December of last year (see the Manchester and 
Salford Sanitary Association’s Weekly Returns), was 0*91 on 
the scale ; showing a difference from my present station of 
1*49 or nearly 1 J-, while the amount is 1*61 above the amount 
detected at my former station.

The disappearance and reappearance were both instanta- 
neous, and no unusual phenomenon was observed.
