818 Abstract of Meteorological Tables. [Dec. 



to my brother Assay Master, Mr. Noton, who kindly sent me copies 

 of some registers made mostly during his absence. The series is broken 

 in many places, and the observations between June and October, 

 1 834, were evidently taken by an inexperienced hand. The single 

 line marked Socotra is from the register kept by Captain Haines 

 while engaged in the survey of the island. As the hours chosen by 

 him were not those of the maximum and minimum, I thought it best 

 to confine myself to the noon readings as a mean of the day. The 

 Calcutta columns are taken from my own registers, published in this 

 Journal. The TirMt diary was kept at my request by my cousin, the 

 late Mr. Thomas Dashwood, Judge at Mozafferpur, who kept it up 

 unremittedly for three years and a half, indeed until a very few days 

 before his sudden and lamented death*. One year of this series has 

 already been published at length in the 2nd and 3rd volumes of the 

 Journal. For the Cawnpore register I am beholden to Colonel G. Pol- 

 lock, C. B. of the artillery. This series is unfortunately intermit- 

 tent, from his having been obliged to send his barometer to Calcutta, 

 in December, 1834 : which, however, furnished an opportunity of com- 

 paring it with my own standard. A little to the right of the Cawn- 

 pore line for 1834, are entered the observations of Mr. Ritchie at 

 Bancoora, for April and May, also abruptly terminated by his falling an 

 untimely victim to the climate. 



The last series to the right I owe to Captain Robinson of the 

 Nipal Residency ; it was made partly with his own and partly with 

 Mr. Hodgson's instrument, which will account for the shifting of the 

 index point in June, 1834. In March also two adjustments were 

 attempted by boiling the tube. These do not affect the utility of the 

 register, when once noted. Captain Robinson's tables are invaluable 

 from the number of periods during the day they embrace, but these 

 will be alluded to hereafter in summing up the figured abstracts. 



I was disappointed of getting any observations from the western 

 hills, (the seat of the grand trigonometrical operations still going 

 forward in those parts,) until after the plate had been long finished 

 and the whole edition struck off, when Mr. H. S. Boulderson of 

 Moradabad kindly transmitted me a file of observations taken by his 

 brother, Mr. S. M. Boulderson, at Simla, between May and Novem- 

 ber, 1834. Rather than lose the valuable additional evidence which 

 this register, at a position elevated about 7000 feet, and situated 400 

 miles to the west of Katmandhu, would afford, 1 have caused it to be 



* An apoplectic fit terminated his life of exemplary public service and pri- 

 vate worth, at the very moment of his quitting employment, and retiring home 

 to devote his latter days to the education of his family in England.
