Abstract
THE ACUTE LESIONS It would seem that by this time all the problems concerned with the fundamental anatomy of the temporal bone should have been worked out and comprehended. Yet during last year, Claus1published a detailed study of the anatomy based on an examination of 1,500 temporal bones. The normal and the abnormal bones are described and discussed in detail. It would take me too far afield to retell the author's findings or even to summarize them. The article should be read and studied in the original. Suffice it here to call attention to this newer report, particularly of interest to those who desire to correlate their own findings with those of this excellent study. The exact location of a suppurative lesion within the tympanic cavity is always useful from the practical, bedside standpoint. Vahldieck's2treatise is therefore noteworthy.
