In Cuba and Porto Rico there is a viper called Juba, or Boaquira, which is a counterpart of the Northern rattlesnake, and the most poisonous of the many species in that region. Among venomous species of the Philippines are two boas and also a viper from nine to ten feet long, which exceptionally pursues and attacks man. This snake is easily killed by a blow on the neck. Another small viper with a club-shaped tail, inhabiting these islands, is nocturnal in its habits, and may get into boots at night. Boots, therefore, should always be inspected before one puts them on in the morning. Usually it is only the young, old, and weak who succumb to snake bite. =Symptoms.=--The symptoms of snake bite of all poisonous species are similar. At first there is some pain in the wound, which rapidly increases together with swelling and discoloration until death of the part may ensue. The vital centers in the brain controlling the heart and breathing apparatus, are paralyzed by the poison. There is often drowsiness and stupor, and the breathing is labored and the pulse weak and irregular, with faintness and cold sweats. =Treatment.=--The treatment consists first in keeping the poison out of the general blood stream. With this purpose in view a handkerchief, piece of cotton clothing, string, or strap should be immediately wound about the bitten limb above the wound, between it and the heart. This will retard absorption of the poison only for a time; it is said twenty-five minutes. The knife is the most effective means of removing the poison by making an oval cut on each side of the wound so that the two incisions meet and remove all the flesh below and around the wound. Bleeding should be encouraged to drain out the poison. The skin containing the wound may be lifted up, and the whole wound cut out by one snip of the scissors where this is practicable. Some advocate burning out the wound with a red-hot wire, or darning needle, instead of cutting, but the treatment is less effective and more painful. Rambaud forbids burning. As to the general condition: if stupor is a prominent symptom the patient must be made to move about and exercise to keep alive his nerve centers. Otherwise one tablespoonful of whisky may be given in half a cup of hot water hourly, to sustain the weakened heart and respiration until recovery ensues.
