THE METEOROLOGICAL RECORD. 



Meteoro- THE earliest weather records kept at the Laboratory which 

 Records. ^ ave been preserved were those made by Dr. Daubeny him- 

 Daubeny, se ^> an< 3 they consist of barometric and thermometric readings 

 1861-7. entered in small 8vo diaries. But inasmuch as the learned 

 doctor only recorded his own personal observations, and 

 was often away from Oxford, his meteorological record from 

 1861 to October 31, 1867 though fairly complete as regards 

 his own environment lacked continuity, for observations on 

 the climate of Rome or Naples would be sandwiched between 

 records of Oxford weather. Nevertheless his observations 

 of the quantity of ozone present in the atmosphere, both at 

 Torquay and at Oxford, were of especial value, and a sum- 

 mary of them is contained in a paper On Ozone and its Dis- 

 engagement by the Leaves of Plants, published in the Journal 

 of the Chemical Society, January, 1 867. 



J. Harris, After Dr. Daubeny's death there is a gap of a year in the 

 1869-73. record, and then a more systematic series of observations with 

 standard instruments was commenced. The installation of 

 the instruments and the method of observation were due to 

 Mr. T. H. T. Hopkins, but the observations were made by 

 John Harris. 



In 1869 Mr. E. Chapman took over the superintendence of 

 the Meteorological Observations, and in this he was assisted 

 by J. J. Manley after the retirement of John Harris. 



The Daubeny Laboratory is situated about 191-62 feet 1 

 above sea-level, and therefore rather lower than the Radcliffe 

 Observatory. The difference of twenty feet in the altitudes of 



1 The height of a brass plate on the plinth of the building above mean 

 sea-level. This height was obtained by levelling from the Ordnance 

 Survey Bench Mark at the foot of Magdalen Tower.
