G. T. Globe, P. Joye, G. Kail, P. Lewis, J. N. Lockyer, B. A. Lomakin, F. McClean,
H. W. Morse, H. Nagaoka and co-workers, H. Oyama, W. Spottiswoode, and
E. Symonp ; and the under-water spark spectrum, by L. H. G. Clark and E. Cohen,
and E. O. Hulbert. The arc spectrum was studied by J. M. Eder and E. Valenta,
F. Exner and E. Haschek, S. Tolansky and E. Lee, A. Hagenbach and H. ELonen,
A. C. Haussmann, U. Kayser, M. Kimura, J. J. Livingood, W. F. Meggers,
H. A. Rowland and R. R. Tatnall, and E. Symons ; the Ultra-violet spectrum, by
G. Berndt, L. and E. Bloch, H. Buisson and C. Fabry, F. Exner and E. Haschek,
G. Kail, R. Lang, J. C. McLennan and A. B. McLay, A. Miethe and B. Seegert,
and V. Schumann ; the electrode light, by W. von Bolton ; the mechanism of the
spark discharge, by S. R. Milner ; the influence of the medium, by P. G. Nutting,
and H. Finger ; the self-induction, by E. Neculcea, P. Joye, and G. Berndt ; and
the most sensitive lines for the spectroscopic detection of platinum by W. Gerlach
and co-workers, and H. de Laszlo. The effect of pressure was studied by
W. J. Humphreys ; and the Zeeman effect, by A. C. Haussmann, and J. E. Purvis.
The series spectra or the numerical relations amongst the spectral lines, or series
spectra, were examined by G. Ciamician, A. Dauvillier, C. C. Kiess and O. Laporte,
O. Laporte and D. R. Inglis, R. de L. Kronig, J. E. Mack, P. G. Nutting,
P. J. Ovrebo, E. Paulson, and C. P. Snyder. The solar spectrum was examined
for platinum lines by E. F. Baxandall, C. C. Hutchins and E. L. Holden,
H. A. Rowland, etc.—vide supra, the occurrence of platinum in the sun.
The absorption spectrum of the vapour was studied by J. C. McLennan and
co-workers, G. D. Liveing and J. Dewar, W. F. Meggers and O. Laporte, and
C. A. von Welsbach. According to J. Formanek, the absorption spectrum of soln.
of platinum salts is not characteristic in the sense of being used for qualitative
tests. There are absorption bands in the blue and violet. Aq. soln. of potassium
chloroplatinate give a pale band about 486O, and bands in the blue and violet.
Platinum salts do not react with tincture of alkanna. The colour and spectra of
the platinum salts were studied by G. B. Buckton, A. Hantzsch, N. Kurnakoff,
C. A. Martius, N. Orloff, R. Samuel, R. Samuel and A. R. R. Despande,
J. Schoras, and L. Wohler and W. Witzmann ; and of colloidal solutions by
A. T. Williams. The fluorescence and fluorescent spectrum of the platinocyanides
of the alkalies and alkaline earths was studied by E. Becquerel, J. Beuel, R. Bottger,
D. Brewster, D. Cernez, J. H. Gladstone, E. Hagenbach, H. Jackson, H. Lehmann,
E. Lommel, G. G. Stokes, and E. Wiedemann.
