Comparison of the data for Providence and for Block Island.—A discussion of the details of the type of results obtained for Providencehas already been given in the Smithsonian report (loc. cit.), and thenew data add no essential novelty. It will suffice, therefore, to com-pare the two classes of curves throughout their extent. Figures 95 to 101 show the daily record of the nucleations of Provi-dence (upper curve) and of Block Island (lower curve) in thousands. 14- IS /8 19 20 22 23 24- 25 2£Fig, 93.—Showing daily record for November 1 to 29. of nuclei per cubic centimeter for the dates given by the abscissas,i. e., from November, 1904, to May, 1905. The prevailing winds andweather and the temperatures of both places are roughly given on thecurves. In the earlier results, from November, 1904, to January, 1905, thereis as yet no striking opportunity for comparison, except that bothcases show a general rise of nucleation to the high maximum follow-ing December 14 and December 20. It is clear that similarity in the 29 NUCLEATION AT PROVIDENCE AND BLOCK ISLAND. 131 two cases must be marred by the snow effect, which is necessarily ofunequal value in the two cases, the depression being as a rule largerand more striking as the antecedent nucleation is higher. On Decem-ber 12 the two curves behave similarly, but not so December 3, 8, 13,18, 2i. The remarkable depression of the upper curve on D
