Roentgenology in some phase is discussed in most issues of our current veterinary periodicals. The use of X-ray as a diagnostic agent has been, and probably will continue for a time to be, the primary subject of our writers. X-radiation as a therapeutic agent is gradually taking the attention of many advanced workers in veterinary radiology. This application has proven its worth in human therapeutics but due to the expense of equipment and lack of knowledge among practitioners it has gained very little headway in its almost fifty years of veterinary application. It is not unwise to predict that courses in roentgenographic technique and interpretation will soon be offered in our veterinary curricula.
