Being engaged, in the course of anthropometrical observations, upon an examination of the hard palate amongst the inmates of an asylum, I have endeavoured to make out a suitable method for the purpose. The proper basis of all such study, I believe, must be cast-taking. Seeing that the procedure to which I am about to refer is only rendered possible by the preparation of a cast of the hard palate, any value which may attach thereto is secondary in importance to the cast-taking. Dr. Eugene S. Talbot, the distinguished American writer upon deformities of the skull and jaws, has devised instruments for measuring the palate, either in the living subject or in casts. For the following method no special instruments are needed; and this may be accounted an advantage. Dr. John R. Lord, clinical assistant at the Joint Counties Asylum, Carmarthen, has been associated with me in working out the details of this method, and I am indebted to him for valuable assistance in cast-taking.
