Electro-physiology and electro-therapeutics : showing the best methods for the medical uses of electricity / By Alfred C. Garratt.

health, and gives more firmness and vigor to the constitution, and power of endurance to the nervous system. At least, so it operates if taken while under repeated treatments by electricity. Astonishing improvement have I seen, now and then, in such, and by such means, as if the constitution were made anew. But (mark !) where the tongue is coated, or is red at its tip or edges, or where the urine is of a deep-red color, or is decidedly scantily secreted, or frequently deposits the heavy lithates of ammonia, then arsenic is not a good auxiliary, but will both fail and do harm by aggravating the existing gastric derange- ment and pains. Correct the stomach thoroughly first, and often it can then do good service in the very same case. Dur- ing the administration of arsenic, the patient should strictly avoid the use of fruits, and all acids, as well as confectionery ; but the occasional application of electric currents enhances its alterative and curative effects. Superficial Nerves in the Facial Neuralgic Region. I wish now to pass in short review the exact anatomical rela- tion of the nerves, or rather to examine such a portion of them os might be seen, for instance, if the skin, fascia, and muscles were all transparent,"and thus try quickly to refresh our mem- ory by a bird's-eye view, as it were, of the geography of the trunks and branches of the more superficial nerves. We know that the tri-facial, or fifth pair, after leaving the skull, spreads out into the most complex distributions and anas- tomoses. There are three principal branches. The ophthalmic branch passes forward through the outer walls of the cavernous sinus, lying externally to the other nerves, penetrates the bony orbit by coming out at the sphenoidal fissure, and then divides into three branches ; and it is exactly at, or from this point that neuralgia oftentimes radiates flashes of excruciating pains. The lachrymal nerve, which is the smallest of the three branches of the ophthalmic trunk, communicates with the fourth nerve, passes along the upper border of the external rectus muscle, traverses the lachrymal gland, and then divides into two cuta- 3T
