RECOMMENDATIONS. 
49 
I. That the Association should employ all the means in its 
power to procure a Register of the Thermometer during every 
hour of the day and night, to be kept at some military or naval 
station in the South of England. 
Note .* Until the phenomena and distribution of diurnal tem¬ 
perature are more thoroughly understood than at pre¬ 
sent, we can hardly hope that any very sure footing has 
been obtained in the study of meteorology. The hourly 
register kept for several years at the military station of 
Leith Fort, in lat. 56°, has shown that we want nothing 
but the combination of a sufficient number of trust-worthy 
observations, in order to obtain results of primary im¬ 
portance to the science, and which may one day enable 
us to arrive at the true form of the daily and annual 
curves of mean temperature with a precision almost 
mathematical. In order, however, to extend the benefit 
of such investigations, it is absolutely necessary that 
they should be pursued in different latitudes. The ap¬ 
plication to rendering available registers otherwise almost 
without value, from not being made at the proper hours, 
will be best illustrated by a reference to the account of 
the Leith observations. (Transactions of the Royal 
Society of Edinburgh, Vol. X.) 
II. That the establishment of such an hourly meteorological 
register be pointed out as a highly interesting object, in refer¬ 
ence especially to the important point of intertropical climate, 
to the Committee of the Association in India. 
III. That the Committee in India be requested to endeavour 
to institute such observations as may throw light on the pheno¬ 
mena of the horary oscillations of the barometer, near the 
equator. Should the concurrence of the Committee on these 
points be obtained, it would probably be desirable that the 
Association should take measures for sending out delicate and 
accurate instruments. 
IV. That Mr. Phillips and Mr, Wm. Gray, jun. of York, 
be requested to undertake a series of experiments on the com¬ 
parative quantities of rain falling on the top of the great tower 
of York Minster, and on the ground near its base. The Com¬ 
mittee have been induced to propose this specific question in 
consequence of the local fitness of the situation, and the 
facilities offered for its solution by the authorities; but it is to 
be wished that similar experiments should be made elsewhere, 
• The notes appended to the Recommendations have been drawn up by 
some of the Members of the Committees since the Meeting.
