_ Being aware of the danger arising from the mixture of 
chlorine and hydrogen gases, when ex posed to the sun’s 
direct rays, we have been sufficiently cautious on that head. 
In one experiment, we mingled, in equal volumes, about 
three quarts of as — they were introduced,—first the

which struck us, as well as other observers. ia
