Lalande\s Propofal of a new Scale of the Thermometer, 



M. de Lalande propofes to adopt a thermometer-fcale, which New fcalc of 

 (hall remedy all the inconveniences of thofe now in ufe. His* ermomctet, 

 mean point is taken from the natural (late of the globe, which 

 he (ixes at 9§ degrees of Reaumur's thermometer, and he takes 

 the 10 millionth part of the volume of mercury for the mealure 

 of a degree. Among the advantages of this inltrument he reckons 

 a fimplitication of expreilion, which will give a facility to com- 

 prehending what was before without meaning to the public. 

 For example, the degree of beat of common fummers, and the 

 degree of cold of our mean winters, will be both expreffed by 

 30 : The degree of 40 will indicate a hot fummer and a fevere 

 winter, &c.; another advantage will be derived from the fmaller 

 interval of the degrees, which will remove the neceflity of 

 having recourfe to fraflions in the greater number of obferva- 

 tions. The boiling point of water is -f- 132^.8 of the propofed 

 thermometer, and — 74*^.4 is the point of the congelation of 

 mercury. Ice melts at ~ 17**. 9 and — 44*^.2 is the zero of 

 Fahrenheit,
