J. HOPKINSON—CLIMATE OF HERTFORDSHIRE. 
1 foot above the ground. Thermometer-stand on the east side of, 
and not far from, the house, the. ground sloping slightly down 
towards the south-east. Sub-soil, chalk. Exposure of the instru¬ 
ments sufficiently open. The observations were discontinued on 
the death of the observer early in the year 1899. 
Berkhamsted (Rosebanlc ).—Rain-gauge 8 inches in diameter, rim 
1 foot above the ground. Sunshine-recorder, Campbell-Stokes. 
Thermometers, rain-gauges, and other instruments, some distance 
from the house, on a level plot of ground set apart for them, the 
general slope of the ground being rather steep towards the south¬ 
east. Sub-soil, clay-with-flints on chalk. Exposure perfectly 
open. There are numerous meteorological instruments the records 
of which are not given here, including several which are self- 
recording, and two percolation-gauges, this being one of the most 
perfectly equipped meteorological observatories in this country. 
St. Albans (The Grange). —Rain-gauge 5 inches in diameter, rim 
1 foot above the ground. Full particulars of this station, a very 
open one, have been given in our ‘ Transactions,’ in the paper on 
“ The Climate of St. Albans” previously referred to. The observa¬ 
tions were discontinued here early in the year 1900 owing to the 
removal of the observer from St. Albans to Watford. They are 
continued with the same instruments at the Hertfordshire County 
Museum, St. Albans. The stations are very near to each other, 
and at both the'sub-soil is gravel on chalk. 
Bennington (Bennington House). —Rain-gauge 5 inches in dia¬ 
meter, rim 1 foot above the ground. Sunshine-recorder, Jordan 
photographic. The instruments are a considerable distance from 
the house, and in a very exposed situation on nearly level ground 
overlooking a great extent of country on the north and east. The 
situation is a very fine one, and admirably adapted for showing 
what is the climate of the Chalk hills of the north of the county. 
As at Berkhamsted there are numerous meteorological instruments 
besides those of which the records are here given. 
New Barnet (Gas Works). —Rain-gauge 8 inches in diameter, 
rim 1 foot above the ground. The instruments are in a rather low 
position near the office of the Barnet Gas Company, but a sufficient 
distance from it and from any other building. The situation appears 
to be rather damp and confined. Although it is not an ideal one for 
the purpose, it well represents the London Clay district on the 
north of London, and it is the only Hertfordshire meteorological 
station which is not on the Chalk. 
There is not a county in England which is better supplied, for 
its area, with meteorological observatories than is Hertfordshire, 
notwithstanding the discontinuance of the Royston station, and the 
stations, as will be seen from the accompanying map (Plate YII), 
are wide apart, and they represent hill and valley, and chalky, 
gravelly, and clayey soils. 
The following table gives the annual means, with extremes of 
temperature, at these stations for the twelve years 1887 to 1898. 
It will be seen that both the mean, and the mean minimum
