The Snook Rontgen Apparatus. • This is a new type of X-ray machine, that obviates the employmentof an interrupter.^ It is entirely free from inverse discharge and candeliver more energy to a Crookes tube than the largest sized inductioncoil. Unlike the latter, its spark-length is estimated according to thekilowatt outiDut; it has, therefore, an energy rating—an important factorin the accurate and scientific construction of apparatus. ^This is the first X-ray machine to be given an energy-rating in-stead of a spark-length rating. The plan of the apparatus is illustrated in the schematic d
