be familiar with the symptoms forerunning black vomit or kidney trouble, and know how to treat them promptly--these are necessaries in nursing yellow fever, and in these the darkey women of New Orleans are more familiar than are the doctors in other towns. On the third day after the attack, when the fever heat subsides, the patient is left in a weak and horribly nervous condition, and for many hours is subject to immediate relapse upon the slightest provocation. Then it is that the tolling of a bell, the sudden shock of a cannon fired by silly authorities, the slightest indigestion or exposure to cold or excitement, will do murder. The stomach is left raw, and for many days only milk, gruel, and crackers are given, doled out in miserly quantity. SUPPLEMENTAL. The following important items do not appear under their regular alphabetical heading, but are none the less efficacious. =Blindness.=--_A Simple Remedy That Often Will Prevent This Dreadful Misfortune._--It is distressing to learn that out of the 7,000 persons blind from their birth in this country, who owe their loss of sight to inflammation of the eyes, at least two-thirds might now have been in the enjoyment of their sight but for the ignorance or neglect of their earliest guardians. It seems that the remedies for the infantile inflammation which causes blindness are both many and simple. Thus, says the London _Figaro_, it cannot be too widely made known that the eyes of the newly-born child, if inflamed, should be washed with pure warm water, and that then a single drop of a 2 per cent solution of nitrate of silver should be instilled into each with a drop-tube. In Germany midwives are enjoined to adopt the above remedial treatment, under oath, and since this has been done the decrease in the number of blind children has been most appreciable. _Increase of Blindness._--Dr. Lucien Howe says blindness has increased in the State of New York during the past five years thirteen times as fast as the population; and the State Charities Commissioners state that the excess in the increase of the insane in the State over the increase in the population for the last nine years has been forty-four per cent. These figures are most startling, especially when it is considered that the modes of treating the eyes and brain are supposed to have been so much improved of late years.--_Ex._
