December, 4-U; total, 4.3-53. But in 1852 J. M. Herbert, Esq., of Eock- 

 Liiids, commenced that valuable series of observations which is still continued, 

 affording us most important rainfall information respecting 1852 (for nine 

 whole months) and for every year since. His record for nine months of 1852 

 is as follows :— April, 0'38 inches ; May, 1'89 ; June, 5 '37 ; July, 2 '87 ; August, 

 478; September, 3'00 ; October, 4'04; November, y48 ; December, 4 '46; 

 total, 36-27. 



In 1872 the total of rainfall at Rocklands was 48-68 inches, and the Titley 

 total, 49-54 inches. 



At Richmond Place, Hereford (gauge 5ft. Sin. from the ground), the total 

 was 42-26 inches, and at Mr. Davison's Nursei-y Gardens, White Cross (gauge 

 1 foot from the ground), 44-50 inches. 



It must be understood that at Kocklands and Titley the rainfall is usually 

 heavier than at any other place in Herefordshire where a gauge has been 

 placed hitherto. 



For the rest I must refer the readers of the " WooUiope Transactions "' to 

 The Tables which, when compared with the work of other observers, will be 

 found, I trust, at all events, as correct and satisfactory as those which have 

 preceded them. 



I subjoin, however : — Some barometrical readings (corrected but 

 not reduced to sea-level) registered by me during a most extraordinary depres- 

 sion in January, 1873 ; A few corrections of errors in figures which have here 

 and there crept into tables, distances, and altitudes, in previous copies of the 

 " Woolhope Transactions ; And the result of a carefid measurement of the 

 river Wye as given in the Ordnance Map. 



1st. Extraordinary depression of the barometer from January 19th to 

 2-2nd, 1873:— 19th: 9 a.m., 28-598 inches; 10.15 a.m., 28518; 1.30 p.m., 

 28-438; 6 p.m., 28-348; 6.30 p.m., 28-338; 7.45 p.m., 28-300; 9.20 p.m., 

 28-280 ; 10 p.m., 28-247 ; night, 28-252. 20th : 9 a.m., 28-265 ; 4 p.m., 28-160 ; 

 7.45 p.m., 28-202 ; 8.30 p.m., 28-242 ; 9.45 p.m., 28-315. 21st : 9 a.m., 28-700. 

 22nd: 9 a.m., 28-509. 23rd: 9 a.m., 29-325. 19th and 20th: Snow with 

 lightning about 8 p.m. ; loud thunder at 7.30 p.m. on [^20th. With the excep- 

 tion of the snow no storms wliatever followed this great faU of the mercmy. 



2iid. Errata, &c. — In " Woolhope Transactions " for 1S70, page 232, The 

 Graig, at Archenfield, Eoss, is said to be 101 feet higher than Eichniond- 

 place, Hereford. This is a mistake. Some verj' carefully conducted observa- 

 tions were made simultaneously at Hereford and Eoss in order to determine 

 the relative heights of the two places, but unfortunately an error crept into 

 the calculations and was carried all through the work, being applied to every 

 one of the observations. Eecent barometrical observations show that 

 Sir. SoutheU's rain gauge at Archenfield is 200 feet above the sea (very nearly), 

 or about 18 feet higher than the surface of the groimd at Eichmond-place. 

 This altitude agrees well with what we know of the fall of the river. The 

 summer level of the Wye at Hereford Bridge is 152-58 feet, and the fall as far
