Drs. Valentine Mott and A. F. Baldwin, of the Carnegie Laboratory; are prepared to inoculate hydrophobia patients according to the Pasteur system. The first patient was the seven-year-old son of Dr. Newell, of Jersey City. Dr. Mott inoculated himself to prove the harmlessness of the method for a healthy man. It has been discovered recently that the juice of the maguey plant is a certain remedy for hydrophobia. =Influenza (La Grippe).=--The first symptoms of the disease are sudden faintness, a chill, and marked prostration, succeeded by headache and a general feeling of malaria, followed by acute coryza, pharyngitis, and slight laryngitis, winding up with bronchitis. Examination shows that the patients are about as sick as persons with a bad cold. The duration of the attack is from 2 to 10 days and upward. An application of 2 parts turpentine to 1 of sweet-oil placed on the chest over the lungs, and then inhale the steam from steeped eucalyptus leaves, is the best remedy we know. =Insomnia.=--The next time a sufferer finds himself awake, say 2 or 3 o'clock in the morning, instead of merely trying to banish the painful thought and repeating numbers, according to habit, let him revert at once to the dream which was the cause of his awakening, and try to go on with it. Sleep will come soon. It is stated on good authority that this experiment, oft repeated, has never been known to fail. A correspondent of the _Lancet_ gives the following method of self-asphyxiation as an effectual remedy for insomnia in his own case: After taking a deep inspiration, he holds his breath till discomfort is felt, then repeats the process a second and third time. As a rule this is enough to procure sleep. A slight degree of asphyxia is thus relied on as a soporific agent. =Leprosy.=--An interesting report by the Hawaiian Board of Health is in our hands; incomplete statistics give the number of lepers in the several islands of the Hawaiian group on January 1, 1888, as 400. A statement of the leper population at Leper Settlement at Molokai for the biennial period ending March 31, 1888, is 749. The report says: "Accurate statistics as to the number of lepers still at large in the various communities of this country cannot be obtained." It is estimated from the best data obtainable, that there were 644 lepers at large on the islands on March 31, 1888. The report says: "The rations furnished each leper at the Leper Settlement on Molokai are abundant for the support of any adult Hawaiian."
