can be classed amongst those by which nature docs its work on a large scale

The President stated the results obtained from three years' 

 observations in the Institution gardens, for which period alone they 

 had been carried on. These results tended to confirm those 

 obtained at the EadclifTe Observatory in Oxford, shewing that the 

 greatest quantity of ozone in the atmosphere occurs in the three 

 spring months of March, April, and May, the absolute maximum 

 occurring in May, while the least quantity is in November. At 

 the same time no clear connection can be traced between 

 the amount of ozone in the air as usually tested, and 

 particular states of weather as indicated by the ordinary 

 meteorological instruments. He believed that Dr. Moffat's con- 

 clusions were in the main correct, viz., " that when ozone is largely 

 present in the air it is accompanied with diminished atmospheric 

 pressure, increasing temperature and humidity, and the prevalence 

 of S.W. or equatorial winds ; and that when in small quantities the 

 pressure is increasing, the temperature and humidity decreasing, 

 and the N.E. or polar winds prevailing." But Mr. Jenyns said 

 that owing to complications arising from the many agencies always 

 at work influencing the atmosphere and the weather, and the 

 neglect of the necessary precautious in making the observations, it 

 was very difficult to estimate the true amount of ozone with any 

 exactness, so as to make manifest the particular atmospheric 

 conditions with which it is associated. 



The Rev. J. Earle then brought before the notice of the Club 

 an interesting passage relating to the history of Bath. As the copy 

 of the Latin document in which it occurs together with the transla- 

 tion appears in the present number of the proceedings, it 

 will be sufficient to allude here merely to the circumstances 

 attending its discovery. During the meeting of the Somerset. Arch. 

 Soc. at Axbridge last summer, Mr. Earle obtained permission from 

 the May6r to look over the parchments belonging to the Corpora- 

 tion. Among them he found this document, which was the oldest 

 of all the documents of Axbridge, and was labelled as a document 

 of Henry I. It was a beautiful document, and a perfect piece of 

 writing of Henry II. (as he saw at a glance), though, as was usual
