Symmers. in the article mentioned, says: In the caseof diffuse metastatic or infiltratitin of the marrow the Rontgen-ray sometimes is powerless to register a shadow. The observation we desireto make here is that whep the patient was atlmitted to the University Hospital,bringing with him the Rontgen-ray plates taken four months Pancoast was able to make the diagnosis of multijile myeloma or 21. i WOOD AND LUCKE metastatic carcinoma from these. Rontgenological studies made at the Uni-versity Hospital after admission confirmed this opinion. Inasmuch as therewas no evidence of a primary carcinoma having existed, and on account ofthe other factors present, it seemed reasonable to settle on a diagnosis ofmyeloma. It will be understood, however, that in order to arrive at acorrect opinion the Rontgen-ray must show in detail the structure of thebones examined and the plates must be read by a person who can detectabnormal difference in density even tliough slight.
