It appears that from nearly the end of March to nearly the end of August, the air 

 within the Minster is colder than the mean temperature of the air -without ; and from 

 nearly the end of August to nearly the end of March, it is -warmer. The excess of 

 -warmth rather exceeds the deficiency, and the epochs of mean annual temperature 

 are retarded, probably about twelve da)'s, -within the Minster, — a result -which may 

 be compared -with some of the conclusions arrived at by M. Quetelet and Professor 

 Forbes in the prosecution of experiments on subterraneous temperature at small 

 depths. 



Furtlwr Researches on Rain at York, by John Phillips, F.R.S., and at 

 Harraby, near Carlisle, by Joseph Atkinson, Esq.; with Remarks by 

 Prof. Phillips. 



At previous meetings of the Association Mr. Phillips had laid before the Section 

 a considerable series of experiments on the quantities of rain received on equal hori- 

 zontal areas, at different heights from the ground, and presented as a general view 

 connecting the results, that each drop of rain grows continually larger as it descends 

 through atmospheric strata successively warmer, itself being cold enough to condense 

 on its surface the invisible vapour of water which exists in the air. On this occasion 

 he brought forward some recent experiments, partly his own, and partly made by 

 Mr. Atkinson, from which it might be inferred, that in the further prosecution of this 

 subject, and in the registration of the quantity of rain for any purpose requiring ex- 

 actness, special care should be taken to choose an unexceptionable situation, and to 

 employ gauges suitable to the object proposed. The statement made by Mr, Phillips 

 at the Glasgow Meeting, of the diminution of the measured quantities of rain, at the 

 small heights of three, six, and twelve feet above the surface, was fully borne out and 

 confirmed by an extract from Mr. Atkinson's register for 1841. Omitting in this 

 year the snowy month of January, we abstract the following measurements of the 

 rain received in funnel-gauges of the usual kind, at Carlisle, on the ground, and at 

 three feet and six feet above : —
