From the above arrangement, and taking each division separately, the author enumerates the applicability of the subcutaneous prothesis, adding such as are not included in the above. 1. Vertical concavity. An overmarked depression at the site of the bony structure and about the root of the nose. 2. Lateral deficiency of form about the root of the nose extending downward as far as the inferior borders of the nasal bones. 3. Median anterior vertical concavity or saddle nose involving the middle third, otherwise the inferior and superior sections. 4. Deviations of the cartilaginous structure about the middle third of the nose, either unilateral or bilateral. 5. Deviation of the lobule. 6. Deficiency of the lobule. 7. Lobular cleft. 8. Subseptal cleft. 9. Collapsed alæ, unilateral or bilateral. 10. Retraction of subseptum. In these ten subdivisions much can be done to bring about a normal appearance of the nose. PRECAUTIONS In selecting a case for subcutaneous injection the operator must well consider the methods to be employed, his successes with such methods, the importance and gravity of the operation, the condition of the patient, the extent of the deformity, the peculiarity of the patient and, particularly, the state of mind of the patient. While at this date of the use of this method of beautifying parts of the human face we may feel certain of the happy outcome of an operation undertaken by the operator, he must not lose sight of the hypercritical person upon whom the work is to be done; even with an outcome gratifying in the extreme from a surgical standpoint, the patient will insist, and that in eighty per cent of all cases, to still further improve them in spite of the fact that a normal appearance has been attained, often leading the operator into doing what he should not do, and eventually undoing his own excellent efforts. The author does not mean to imply this as a weakness on the part of the surgeon, but cannot impress too deeply upon him the unreasonable demands of a person insanely bent upon having the alabaster cheek ideal of the poets, the nose of a Venus, the chin of an Apollo, the neck of swanlike form, etc. The patient believes it lies in the power of the cosmetic surgeon to do with their malformations as a sculptor would model in clay and will insist upon gaining their ideal beyond all reason.
