High exhaustion. 31. Standardization with ions.—The endeavor to standardize the coronas by precipitating the fog particles upon ions lead to peculiar results, which makes it necessary to discuss the subject independently in Chapter V. In fact, about one-half of the water nuclei wrhich should be present after the first evaporation of fog particles vanishes independently. Half the ions are thus not represented by fog particles, except in the first precipitation. The remainder in the subsequent exhaustions behave more normally. 32. Further data.—Results obtained in case of the intermediate exhaustions 5p3 = 17 cm. are liable to be most serviceable for the con- struction of a practical table, and two further series were therefore investigated under atmospheric conditions different from the above. These results are given in table 20 and in figs. 17 and 18. In both series the agreement between the observed and computed values of 5 within 5 = 10 is surprisingly close. The attempt was, moreover, to compute tables 16 and 17 under modified suppositions, putting [Sp2] = ; as in table 20 and then reducing all data to 24°. The results are of no marked advantage over the earlier data and are therefore Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original work.
