ON THE REDUCTION OF METEOROLOGICAL OBSERVATIONS. 83 
Bangalore.—If we may deduce a barometrical character from only two 
recorded terms, this would seem to be a very peculiar station, its peculiarity 
consisting in an all but perfect repose of the mercury, and the absence even 
of any appreciable amount of diurnal oscillation. But of course no conclusion 
can be rested on so small a basis, nor am I in possession of any meteorological 
journals or recorded observations from which to institute further inquiry. 
Cathmandu (Nepaul).—A very elevated station, the barometer standing 
at 25°3 inches. ‘Three recorded terms only have come to hand, being those 
for March, June and Sept. 1837. In all the diurnal oscillations are very 
strongly marked. In that of March a temporary disturbance at the 6th hour 
P.M., arising doubtless from a misreading of 071 inch, mars the regularity of 
the curve, and if this be allowed for, the excursions run as follows :—

From Sikkim (? Darjding), a Subhimalayan station, we have a single term, 
that of March 1837. ‘This also is a very high station, the mercury standing 
at 23:2. Its curve is smooth and flowing in an eminent degree, and the 
diurnal oscillations quite as strongly marked as in any of the Indian stations, 
the excursions being as follows :— 
Sum of the greater 07114; sum of the lesser 0°048. 
Asa contribution to our knowledge of the periodical movements of the atmo- 
sphere at high levels, these possess no small interest in proportion to the pau- 
city of recorded observations in such circumstances. 
From Hobart Town and Port Arthur we have six terms. In all of them 
the barometer was much and irregularly agitated; but as there is no station 
within comparing distance, nor have any observations from ships at sea in 
that region, simultaneously made, been received, it is impossible to ground 
any conclusion on them, the casual disturbances being too great to admit of 
mutual compensation in so moderate a number of terms. 
In discussing the diurnal fluctuations for the several stations above, I have 
said nothing about the epochs, except for Mauritius. In fact, these elements 
are too delicate to be obtained with any degree of confidence or precision 
otherwise than by a very much more extensive course of observation. How- 
ever, it is evident that ber do not differ widely from the generally received 
hours (45, 108, 168 and 22"). 
South Africa. 
This group affords but three stations on land, viz. two at the Cape very 
near together, and the other at Bathurst, far to the eastward, There are, 
however, two excellent sets of observations by Captain Henning on board 
the Windsor, within limits of comparison. The whole number of terms ob- 
served iseleven. In all of them the barometric range was moderate. The sea 
observations run nearly parallel to those at the Cape, but there is no prominent 
feature which it is possible to seize capable of identifying any atmospheric 
disturbance-in its progress from station to station, On the other hand, so far
