The influence of water vapor upon nocturnal radiation, .1. R. Sutton (Sci. 

 Proc. Roy. Dublin Soc, n. ser., 11(1905), No. S, pp. 13-3S). — The author cites evidence 

 to show "that Tyndall's discovery of the absorption and radiation of beat by the 

 vapor of water has been too hastily applied to meteorological problems," and sum- 

 marizes the results of a series of observations at Kimberley on the absolute and rela- 

 tive humidity at 8 p. m. as related to the subsequent fall of temperature, from which 

 the conclusion is drawn that there is " no trace of a fall of temperature depending 

 upon the quantity of moisture present." 



The observations " show a relationship between the nocturnal cooling of the air 

 and the relative humidity, but not any relationship at all to the absolute humidity. 

 ... It is a dry air which, of itself, a priori because of its feeble radiative power, 

 should cool more slowly than a damp air. We have then to establish a connecting 

 link between these two facts. It is to be found, it seems, in the dependence of the 

 cooling of the ground upon the hygrometric state of the air." 



Observations on the surface cooling between 8 and 11 p. m. of a "bare patch <>f 

 red sand" show that comparing the falls of soil temperature with the relative 

 humidity it was found "that a simple division by three gives practically the same 

 value as those for the cooling of the air, so long as the air is not more than half 

 saturated. For humid states in excess of this, the air cools faster than the ground. 



"The falls of earth-temperature as compared with the dew-point are of exactly the 

 Same nature in the two series as those of the cooling of the air. namely, that they 

 increase at first to a dew-point of about 40-45°, after which they decrease again. The 

 explanation is that the humidity of the air chances to have on the whole its mini- 

 mum values when the dew-point is about 40-45°. 



" We see, then, that the lower air takes its temperature chiefly from the ground, 

 but that the great radiative power of its contained water vapor, when the relative 

 humidity is high, lowers its temperature somewhat Easter than it can absorb radia- 

 tion from the ground."
