whose make no information is to hand; but the double record, 
lower as well as higher, gives it considerable weight. 
Each decade has a marked characteristic. High pressure in 
the Forties; cold and dry in the Fifties; warm and low 
pressure in the Sixties; heavy rainfall in the Seventies, and 
highest pressure, but most days with rain, in the Eighties. Next 
to the plienomenal rainfall of the Seventies, perhaps the glorious, 
warm summers of the Sixties was most marked, at any rate in 
the minds of such as were then in their youth. 
POST. SCRIPT.—At the last moment, whilst correcting the proofs, three tables 
of Meteorology were found at Bootham referring to years from 1831-7. The chief 
is a table giving the mean for pressure, temperature and rainfall for these seven 
year. The yearly values are 29-98 ins. (^corrected), 48-4° and 23-39 ins. The 
monthly curves for the barometer (max. 29.98 in June ; min. 29*86 in Oct. and 
29 88 in Nov.) and thermometer (max. 60-1° in July and 36-9 in Jan.) are similar 
to the 50 years’ cuives, but the “pluvial” curve, as we might expect, varies 
considerably. August, however, still gives the maximum (2-40 ins. against 2 69), 
but the minimum falls in May, not April, and January has a less fall than 
February. As the table, however is unaccompanied by explanation, it is not safe 
to interpret it too positively. 
NOTE.— The highest mean for March (30*56 in 1845) has been found to rest on 
a misprint in the Table of that year. As a consequence that value, and the highest 
for the year, need alt“ring, tl e former to 30*27 in 1854 ; the laUer to 30*34 in 1886. 
This removes the chief anomaly of the barometer curves. The mean for iMarch 
now becomes 29-884 and for the )*ear 29 904.
