It occurred to me that if thesedifferences are brought about by usage,the causing of the discharge to passthrough in a reversed manner until thephenomena in a high resistance tubewould resemble, in certain particulars,the phenomena observed in a tube oflow resistance, reversed, it would indi-cate the proper degree of reversal andat the same time help to solve the ques-tion of the heretofore believed high vac-uum barrier as engendered by usage. In fact, both objects are accomplishedby reversal. If the discharge is made togo through reversed until the phenom-ena resembles in certain particulars thatseen in a tube of low resistance, and ifthe tube then be properly connected, itwill usually glow with most brilliant ra-diance; if it does not, by slight assist-ance, readily obtained by interrupting thenegative discharge at pole with inter-rupter, and if necessary, further intensi-fying the discharge by interrupting itwith the foil near cathode terminal wire, THE AMERICAN X-RAY JOURNAL. 237

The American X-Ray Journal was the first radiology journal in the United States. Its first issue was published in May 1897, its founder and first editor was an American physician Heber Robarts (1852–1922), who took an early keen interest in the new Roentgen rays. Robarts was also a co-founder of the Roentgen Society of the United States, the forerunner of the American Roentgen Ray Society (ARRS). In its earliest days the journal struggled to attract any important articles as the majority of the pioneering researchers in the fledgling field of x-rays would prefer to see their work published in the established medical journals. The initial subscription rate for the new journal was one dollar per annum (payable in advance) or two dollars for overseas subscribers. Alternatively, it was ten cents per issue, or twenty cents for readers outside the US. In 1902, Harry Preston Pratt, an American physician from Chicago with an interest in electrotherapy, purchased the American X-Ray Journal from Dr Robarts. In 1904, the American X-Ray Journal subsumed the Archives of Electrology and Radiology (which had previously been the American Electro-Therapeutic and X-Ray Era). Following this, the journal was re-named and re-focussed as the American Journal of Progressive Therapeutics, and this published its last edition in January 1906.
