The chief object of this technique is to provide a convenient record ofradiographic work for the use of the physician or surgeon, but there areother conveniences, chief of which may be that of the radiologist, for whenhe comes to compare a large number of cases the prints obtained of thecomplete examination are most convenient; he can carry a hundred or twoof these records, and when comparing the sets they are much more con-veniently handled than the original plates. /2 After mea. Splenic Flexure Fig. 285.—To show the marking of the parts ; this is arranged for by having a complete set of rubber stamps prepared. A further advantage will be found when it is desired to prepare casesfor publication. In order to illustrate further the advantages of a technique of this kind,a number of reductions from 15 by 12 plates are shown (see Plates LXIII. andLXIV.). The reduced prints are undoubtedly the more complete so far as therecord is concerned, but it is not always possible to get a uniform set of nega-tives from which to obtain the reduction, a negative which will give a verypoor reduced print may be quite good enough to give a good tracing, so insome cases it may be well to use both methods. A number of tracings ofthe screen examination may be available when no negative has been taken ;these tracings may be placed upon the table and reduced by using thepantograph. By using the combined method the record of the case maybe rendered more instructive and complete than
