XIII. 
METEOROLOGICAL OBSERVATIONS TAKEN AT THROCKING, 
HERTS, DURING THE YEAR 1883. 
By the Bey. C. W. Harvey, M.A., F.B.Met.Soc. 
Read at Hertford, 25th April , 1884. 
Position of Station, Lat. 51° 57 / N., Long. 0° 3' W\, Bib 
District; Height of Station above sea-level , 484 feet; Times of 
Observing, 9 a.m. and 9 p.m. 
There is little in the meteorology of 1883 which strikes one as 
in any degree abnormal. That which attracted the greatest 
amount of interest was, no doubt, the very remarkable sunsets of 
November and December, for which it seems difficult to find a 
satisfactory solution. 
In the table in which I usually compare the year with an 
average year, I have determined for the first time to dispense with 
the pressure and temperature values of other places, i.e. London 
and Yarmouth, and to confine myself entirely to that which relates 
to my own station. Having only the observations of four years 
complete, the set of means with which I have ventured to compare 
the year 1883 cannot be said to represent the normal state of 
either pressure, temperature, or rainfall at this particular station. 
A four-year period is, I know, much too short to give very reliable 
results; still, as years go on, this table will, I hope, become more 
and more reliable.
