Note 314 — PART V.—MORE OR LESS VOLATILE POISONOUS SUBSTANCES CAPABLE OF BEING SEPARATED BY DISTILLATION FROM NEUTRAL OR ACID LIQUIDS. (continued 3)
Reading edition
Any considerable amount of phosphorescence can, however, be observed in twilight.
[315] Many volatile substances destroy the luminous appearance of phosphorus vapour, e.g., chlorine, hydric sulphide, sulphur dioxide, carbon disulphide, ether, alcohol, petroleum, turpentine, creasote, and most essential oils. On the other hand, bromine, hydrochloric acid, camphor, and carbonate of ammonia do not seem to interfere much with the phosphorescence.
[316] Fresenius states that he and Neubauer, with 1 mgrm. of phosphorus in 200,000, recognised the light, which lasted for half an hour.—Zeitschr. f. anal. Chem., i. p. 336.
