A CONTINUOUS RECORD OF ATMOSPHERIC NUCLEATION. 

 TABLE I. — Continued. 



' In this and the other cases fresh nuclei were aspirated into A by passing room air over phosphorus. 



TABLE 2.— SUMMARY OF THE PRECEDING. NUCLEI INTRODUCED INTO RE- 

 CEIVER BY ASPIRATING ROOM AIR OVER PHOSPHORUS. 



Remarks. 



I. Insulation (morning) 



II. " (afternoon) 



V. Slow current of phosphorus nuclei (liters per min.) in saturated moist air.. 



VI. Do., but fast current (10 liters per min.) 



VII. Phosphorus nuclei enter condenser by diffusion 



VIII. Blown in with moist air (slowly) 



IX. Phosphorus nuclei enter directly from tubular ionizer. Fast current of 



moist air 



X. Air current stopped; observation within 5'" 



XI. Slower moist air current through tubular ionizer directly into condenser. . 



XIII. Do. Slow moist air current, but fresher phosphorus 



XIV. Ionized air current stopped: immediately after 



XV. Insulation 



Cases V, VI, tested for coronas, gave the usual intense and full series, beginning 

 with diffuse dense fogs.
