The lesion is in all probability a degeneration of the peripheral nerve fibres and of the nerve cells in the cerebral cortex, together with a chronic congestion or inflammation of the pia mater. This lesion explains well the symptoms, although it is curious that alcohol should not attack the spinal cord, but only the highest and lowest part of the nervous system, if one may so call the cortex of the brain and the terminal branches of the peripheral nerves.--_Detroit Lancet._ * * * * * NOURISHING THE TISSUES OF THE TEETH.--Dr. Frank Abbott says: For a number of years past I have entertained the views that there was some difficulty existing not due to an insufficiency of lime-salts, which occasions so many faulty and imperfectly formed teeth. With that idea in view I have advised exercise in the open air and other kinds of treatment for some patients which would favorably affect their digestion. That the food ordinarily taken contains sufficient lime-salts to form and to sustain the teeth I have no doubt (except in cases of extreme anemia, during gestation and lactation). I believe the fault is beyond that. There is a lack of proper nourishment of the tissues, due to imperfect digestion, which depends again on the proper "nerve tone." I believe this to be the real cause of the difficulty. It is reasonable to suppose that any _tonic_, whether taken in the form of exercise in the open air, or in any other form, which affects favorably other portions of the body, will affect the teeth favorably as well. When we have _ascertained the functions of the great nerve-centers_, and those functions are assured, then we will probably have more perfectly formed teeth.--_Items of Interest._ [Footnote A: See Gradle on "Bacteria and the Germ Theory of Disease," pp. 39 and 151.] End of the Project Gutenberg EBook of The American Journal of Dental Science, Vol. XIX.
