Two tested rain-gauges have been recently jjlaced in the valley of the 

 Wye, but as they have not been long enough at work to measure the rainfall 

 of a complete year, I pass them over in our present report.* 



Our greatest fall in twenty -four hours during the past year (at Hereford) 

 •was measiired on the 1st of October, and is therefore placed to the September 

 account ; it amounted to l'G20 inch. 



Table IV. is a repetition of a similar table given in the " Transactions " of 

 1868. In drawing up this table I am very much indebted to Mr. G. J. Symons 

 (so well known as taking the lead in the rainfall department of meteorological 

 science) for some yearly totals which did not reach me by local information, 

 and also for the detection of a few slight mistakes which appeared in the reprint 

 of rainfall tables in the "Transactions" for 1867. I am also indebted to the 

 observers whose names are subjoined for materials for Tables III. and IV. :— 

 Rocklands, J. M. Herbert, Esq. ; Hagley Park, Arthur Hutchinson, Esq. ; Titley, 

 Uliss Boddington ; Ross and Leominster, Messrs. H. and E. P. Southall ; Sellack, 

 Rev. AV. Clement Ley ; Stretton, Rev. H. C. Key ; Tupsley, Mr. Ballard ; 

 Blue School, Mr. With ; and White Cross, Sir. Davison. I have also received 

 some rainfall returns which I would gladly enter in the report, but from want 

 of space it has been necessary to print complete yearly returns only.* 



Table IV. will enable anyone at a glance to form a judgment respecting 

 the comparative ivetiiess or dryness of any year from 1818 to 18&9. Due allowance 

 must, of course be made for difference of height above the sealevel, and it 

 would have given me much pleasxire to have settled this point once and for ever, 

 but more imi)ortant matters have occupied my time and attention, and I have 

 been unable to render this service to my scientific friends. 



This much, however, is pretty certain — Hereford, at the Cathedral yard, 

 is about 190 feet above the sea ; Pool Cottage is 300 feet above Hereford, and 5i 

 miles south of it ; Titley is 16^ miles N.W. of Hereford, and higher than 

 Hereford, but I am unable to give the altitude ; Rocklands is situated 14 miles 

 S.S.E. of Hereford, and is said to be 100 feet above sea-level. West Lodge, 

 Leominster, is about 12 miles north of Hereford, and 264 feet above the sea. 

 Mr. Southall's residence at Archeniield, Ross, is, I believe, about 300 feet above 

 the sea (simultaneous barometrical observations are being carried on at present 

 to determine this point), and 11^ miles S.E. by S. of Hereford. Stretton is 

 about 2 miles W.N.W. of Hereford, and 10 or 15 feet higher. Sellack is 8^ 

 miles S.S.E. of Hereford, and the churchyard is 50 or GO feet higher than the 

 Cathedral Close at Hereford. Tupsley is 1^ mile nearly E. of Hereford, and 

 perhaps 50 feet higher. 



It is very important to determine, if possible, the altitudes of our guages 

 above sea-level, as the following sentence from Sir. Symonds' " British Rainfall 

 for 1807 " will show : — " In all, except mountainous districts, the amount of rain 

 collected increases about 2^ per cent, per 100 feet of increased elevation ; there-
