VIL An Account of an extraordinary Eruption of 
Mount Vefuvius in the Month of March, in the 
Tear 1730, extracted from the Meteorological 
Diary of that Year at Naples, communicated 
hy Nichol. Cyrillus, M. V. S. S. 
T H E Thermometer ufed in this Diary , was made 
by Mr. Haukshee r in which the Freezing-Point 
is marked at 65 Degrees under the Point extreme Hot ; 
but the Defter obferves, that at Naples Water will 
freeze when this Thermometer Hands at ys Degrees 
only: Which, he is of Opinion, feems to argue, 
that there is fomething elfe befides an intenfe Degree 
of Cold required for freezing Water j that the Air of 
Naples abounds in i t r, more than the Air of London j 
and that this may probably be of a fajine Nature ^ 
becaufe when we turn Water into Ice by the Help of 
Snow, it is necelTary to mix Salt with it.
