Any great restlessness or excessive pain may require a dose of Opium at bedtime (283). N.B.—Whenever the burn is in the neighbourhood of the joint, or in the neck, it is important that the parts should be kept in a straight or stretched position, otherwise contraction is apt to result during the healing process. _Cancer._ To relieve the pain and restlessness, give Opium (283) or Tincture of Datura (128). _To correct the fœtor of the discharge_, apply relays of Charcoal Poultices (91), cleansing the ulcer each time the poultice is changed with Borax Lotion (59). N.B.—On the smallest suspicion of a cancer forming, no time should be lost in placing the case under regular medical care. _Carbuncle "Rajah Boil" of the Natives._ The treatment of the early stages is similar to that for Abscess (_ante_); only if leeches are deemed necessary, they should be placed round the edge and not on the hardened surface. When ulceration sets in, the _Toddy_ Poultice (355) is useful in stimulating to healthy action; and the removal of the slough is greatly accelerated by the daily practice of Irrigation (395). Turpentine Ointment (367) or Petroleum (412) also prove useful in this stage. Should there be much fœtor, apply Charcoal Poultices (91) and the Borax Lotion (59) as advised in _Cancer_. Opium (283) may be necessary to relieve pain and give rest. When the slough has come away, the ointments advised in paragraphs 367 and 372, or Ceromel (167), may be used as dressing. A generous animal diet, with a daily portion of stimulants, should be allowed, and tonics as Chiretta (98, 99), or Country Sarsaparilla (163) administered. Whenever practicable, the case should be placed _under proper surgical care_, as incisions are often necessary for the removal of the slough. _Cassava Root, Poisoning by._ Give Lime Juice (234). _Castor Oil Seeds, Poisoning by._ Give Lime Juice (234). _Cataract._ Datura (128). _Catarrhs or Colds_ may often be cut short at the outset by a draught of hot Infusion of Ginger (156) or White Wine Whey (428) at bedtime, and covering the body well, so as to produce copious perspiration. A Vapour Bath (396) will answer the same purpose. To relieve feverishness give Solution of Nitre (264), Decoction of Abelmoschus (2), and Country Ipecacuanha (370). Inhalation of the fumes of burning Turmeric (359) manifestly relieves troublesome congestion or fulness of the head, nose, &c. See also _Cough_.
