N.B.—Convulsions and nervous affections occurring in Natives and Anglo-Indians are very frequently due to the presence of worms in the intestines; their existence may perhaps be unsuspected, or even denied; hence in all cases which resist ordinary treatment, it is advisable to give a trial to one or more of the remedies recommended for _Worms_, especially those for the _Lumbricus_ or _Round Worm_, which is so extensively prevalent in India. _Corns_ are best treated by immersion in hot soap and water, paring off the hardened cuticle and wearing a piece of thick plaster, with or without a hole in the centre, to ward off the pressure and friction. _For Corns between the Toes_ nothing is more effectual than a piece of thick blotting-paper worn so as to protect the opposing surface: it should be renewed daily. If only ordinary thin blotting-paper be available, two folds are advisable. _Corrosive Sublimate, Poisoning by._ See _Mercurial Salts, Poisoning by_. _Coughs._ Try Sal Ammoniac (329) and Country Ipecacuanha (370); with Rice Poultices (322) or Mustard Poultices (247), Turpentine Liniment (366), or Camphorated Opium Liniment (291) externally, and the inhalation of the vapour of Hot Water (390) or Decoction of Abelmoschus (2). If severe, a blister (349, 350) to the chest may be necessary. _In Chronic cases, especially when attended with much expectoration and debility_, give Fish Liver Oil (140). _In Spasmodic Coughs_, violent paroxysms may be relieved by inhaling the fumes of Nitre Paper (268), or by smoking Datura (129). _For the Cough of Old Age_, Cubebs (126) is worth a trial. _For the Cough of Childhood_, Syrup of Country Liquorice (6), Asafœtida (37), Honey and Vinegar (166), and Fish Liver Oil, may be resorted to according to circumstances. Camphor Liniment (70), Mustard Poultices (247), or bags filled with hot salt, or better still, Betel Leaves (48), applied externally, tend to _relieve difficulty of breathing in these cases_. Sponging the chest with Vinegar is thought to lessen the liability to attack (378). _Coup de Soleil._ See _Sunstroke_. _Croton Oil Seeds, Poisoning by._ See Par. 234. _Croup._ Sulphate of Copper (111) as an emetic, and Hot Water Stupes (390) externally, are valuable accessories in the treatment of this disease. "The best and readiest emetic," writes Dr. Aitchison, "is a pinch of Ipecacuanha Powder placed dry at the back of the child's tongue. This usually acts instantaneously, so be prepared for the emergency. Sponges dipped in extremely hot water, then rinsed out, and continuously applied over the throat, will often check a coming attack. Poultices are useful, but are apt to do much harm if allowed to become cold. Mustard poultices should not be applied, as without due care they are apt to make the skin tender, and thus prevent the use of hot fomentations."
