COMMENT Just as in all cancers which are exposed to infec¬ tion, the presence of secondary processes in this case seems to have contributed largely toward bringing about the final fatal outcome. It is rather noteworthy that in the microscopic sections relatively few tumor cells can be found invading the adventitia of the aorta (h), while the media and intima are apparently Fig. 4.-High power photomicrograph of section shown in Figure 3 , showing the slight carcinomatous infiltration of

... a at h. The inflammatory exúdate is seen at /. entirely free from invasion. Since the amount of infection is relatively great, and the amount of can¬ cerous infiltration small, it is logical to conclude that the destructive inflammatory processes which accom¬ panied the ulcerating tumor greatly contributed in bringing about the final perforation of the aorta. To these factors, of course, must also be added the results of the blood pressure within the aorta and the destruc¬ tive effects of the boluses of food passing down the gullet. It certainly appears true, however, that, in this loca¬ tion, serious sequelae may result from cancerous infil¬ tration, which is relatively much less extensive than that necessary to bring about equally grave results, for example, in the stomach or intestines. This may be explained by the fact that, in the latter organs, the infective processes are accompanied by a greater pro¬ tective reaction on the part of the connective tissues. A View of Christian Science.-Christian Science was th* offshoot of an abnormal mind which grasped a few of the basic facts of the good influence of hope and faith, seized on these well-recognized cardinal principles of psychotherapy and, by a species of logic of the most illogical kind, erected thereon a superstructure which violated all the tenets of sound reason. It must never be forgotten that this super¬ structure was built of materials, the chief of which were faith and hope. Everything else was discarded. Whatever was pleasant was given space ; whatever was unpleasant was denied space. Unrealities, if pleasant, were eagerly sought; realities, if unpleasant, were cast away. The result was a marvelous structure, a psychologic palace of straw. The wondrous thing is, not that the founder of Christian Science could conceive and erect such a structure, but that she could get such vast numbers of followers to subscribe to her labors, to accept the structure, to surround and house themselves with similar mental architecture.-Northwest Medicine.
