le. The first ob-servation from this second view-point,was of course for the purpose of findingthe shot, and they were, as has been said. practically in a thin layer, the edge ofwhich layer was toward the observer.One of the forked sights was then placedon the Fluorometer arm nearest the ob-server, and thus nearer the screen of theFluoroscope, in such position that thelayer of shot intersected the notch of thesight and about midway of its length:that is up and down the limb. On theupper arm of the Fluorometer nearestthe tube (now the crosspiece) was placed a second forked sight, at a point equallydistant with the first from the left side otthe Fluorometer. The tube was thenshifted until the grooves of the sightscoincided: in other words, until a straightray passed through both. It was thennoted by means of the metallic grating,which had been placed on the level of thetop of the table under the Fluorometer,that the layer of shot appeared aboutone-half inch to the left of the right line

The tube was again shiftedslightly until the straight ray was throughthe notch of the upper sight, throughabout the center of the layer of shot, andthrough the notch of the lower sight,thus bringing the three in line, so that acoincident shadow was thrown on thescreen of the Fluoroscope. All that now remained was to draw aline in India ink on the upper surface ofthe limb, corresponding in position withthe notch of the upper sight, and to drawa similar line on the under portion or calfof the limb, corresponding with the notchof the lower sight. When thus correctedby the Fluorometer, this line was twoand three-fourths inches long, and ofcourse ran at right angles with the linewhich marked the cross-section of thelimb. The sights were then removedand another Fluorograph, (shown inFig. 2) was taken, as a matter of record. A few days later
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.
