Abstract of Meteorological Tables.

Of the two barometers registered at Katmandhu, that of the Resi- 

 dent has been preferred, for 1834. Capt. Robinson's tube for that 

 year stood a quarter of an inch lower, and was hardly sensible to the 

 diurnal oscillation. After boiling it in the month of September, however, 

 it rose to within .02 of H.'s, and exceeded the latter in oscillation by 

 .03. This and the circumstance of the hour of maximum 9 to 10 a.m. 

 being unfortunately omitted among the numerous periods of the day 

 selected for register, render not only the absolufe amount of diurnal 

 motion still uncertain for Nipdl, but also prevent our calculating 

 the annual average. I hope the series 1 am now promised by Dr. A. 

 Campbell for 1837 will supply the want. 



1 reserve for a separate notice the calculated elevations connected 

 with the Nipdl series, as they are affected by the error alluded to in 

 the preceding remarks, of assuming 30 inches for the barometric 

 zero at the level of the sea, 



The state of the wind in the valley has not been noted, but the fall 

 of rain is recorded with precision, the average amount being about 

 50 inches. 



The series for Simla does not comprehend an entire year, and will 

 not therefore furnish averages. The temperature appears to be that 

 of the interior of the house.

The range at 7§ A. M. is also given for the month of May, the mean of the baro- 

 meter being 23.79S ; which proves the regularity of the nocturnal tide in these 

 elevated regions. 



I must, for want of time, leave to a future opportunity the further 

 analysis of the above tables, and the deduction of general average re- 

 sults from the Calcutta tables for the past five years. Meantime, I will 

 conclude with the insertion of a table of the temperature at Kandy in 

 Ceylon, obligingly contributed by Captain Ord, R. E., and a note on 

 the temperature of the Brahmaputra in Assam, compared with that of 

 the air at the same time by Dr. W. Griffith.
