Expose an impressioned plate, that has been sufficient time in the camera to become solarized, to the vapors of bromine, and the impression will be fully developed and exhibit no signs of solarization. The exposure over the bromine most be very brief. Chlorine or iodine will produce the same result. The latter is preferable.
Throughout the year 1841, I used, with great success, chloride of iodine, applied as one coating occasionally in conjunction with Mr. Wolcott, attempting the use of iodine, bromine, and chlorine, and at times with more or less success.

Those having Humphrey's Journal at hand, can refer to vol. i. p. 142. To use Bromine Water or other Accelerators in Hot Weather.
Later researches have brought out a striking analogy between the properties of ozone and chlorine, and have led to conclusions as to the dangerous effect which the former may produce, in certain cases, on the organs of respiration.

During the big operations before Verdun, however, the enemy did their very utmost to substitute the gas mask M2 for the respirator XTX. Gas mask M2 was a protection against Green Cross.
The acid causes this separation of the elements, and the separation of the elements causes the disorganization, and often the charring of the structure. This law is resolved into the two following laws. Chlorine has a powerful affinity for bases of all kinds, particularly metallic bases and hydrogen.
We knew that they were ready for another gas attack, for our artillery had burst a tank in the German trenches and the yellow fumes of chlorine gas had been identified. A German gas bag used for getting the wind drift was also brought in to us for examination, showing that the enemy was awaiting a favorable opportunity.
Then they sat down near one another, and formed a large semicircle in front of the fire. With lowered faces, and swinging one leg crossed over the other knee, they uttered deep sighs at intervals; each one was inordinately bored, and yet none would be the first to go. He also carried a large jar full of chlorine water, to keep off all miasmata.
