氨和碳酸气体。
给火与水的编辑：
我已经准备了向美国和加拿大消防员致辞的宝贵纸张的沟通，我在抑制火灾中就“氨”和“碳酸气”的相对功率和效率进行了比较论文，如今市场上被称为“ Babcock”，“冠军”，“ Holloway”和“ Lindgren”化学消防车。I was just about to mail the communication when I received FIRE AND WATER of April 18 containing W. H. Bringhurst’s letter of April 7 from Seattle, Wash. I will hold the thesis until Mr. Bringhurst has an opportunity to answer a few questions on the subject of extinguishing fire;, by gases emitted from chemicals.
