Not illustrated. 1905 Excerpt: ...the latter is stronger in the visible portion, the spark possesses the greater intensity in the ultraviolet, and some new lines appear, e.g. 4523/20/15/08. Many arc lines are strengthened, (e. g. 2986, 4550/84, 4924, 5018); others are weakened (e. g. 3021, 3100). A number of the stronger lines (for the most part enhanced lines) are found at 2338, 2344, 2382, 2399, 2405/13, 2586/98, 2600 (lens), 2743i 47/49:56, 2841, 3154, 3228, 3441, 357-3581-3585 (2 comps.), 3632, 3735, 3744/49 (each 2 comps.), 3816/20, 3841, 4046164/72, 4132, 4250 (2 comps.), 4261/72, 4308/26/84, 4404/15, 4476/82/94, 4529, 4860:71/91. 4919/20/24 (lens), 4957, 5139/67/69 (lens), 5227/33/70, 5324/28, 5370, 5445. Compare Nos. 187 and 251. In (198) the air lines are relativelv weak, because a magnified image of the spark was projected and only the outer part fell on the slit. 251 (Chart XXVI). Iron Spark. Material: spark between metal poles, self-induction in circuit. Correction: -(-3. Remarks. The self-induction here used was so large that the lines of the air spectrum are quite blotted out. Under these conditions the intensities of the iron lines are changed in the direction of an approach to the arc spectrum. The lines between 50 and 55 become stronger, the intensities of most of the lines lie between that of the ordinary condensed spark and the arc (e. g. 5659 (lens), 5616, 5587, 5237. Some lines appear which are absent in the usual spark (e. g. 5193), while others show the opposite behavior (e. g. 5195, 4584/50/23/20'16'08; and still others are found in the arc which are absent in the spark with self-induction (e. g. 4401, 4615/30, 5195). Compare Nos. 187, 188, 77. It is also to be noticed that all lines gain in sharpness when self-induction is used. 77 (Chart III). Irpn Flame. Material: ..
