CLASS II. i. 3. 9= OF SENSATION. 201 



for a child of about three years old was one-fixth part of a grain 

 of calomel, one-fixth part of a grain of opium, and two grains 

 of rhubarb, to be taken twice a day. 



The opium promotes abforption from the mucous membrane, 

 and hence contributes to heal it. The mercury prevents ul- 

 cers from being formed under the mucous membrane, or cures 

 them, as in the lues venerea ; and the rhubarb is neceflary to keep 

 the bowels open. 



M. M. Aniimonial vomits frequently re'peated. Mild ca- 

 thartics. Cool air. Tincture of cantharides, or repeated blif- 

 ters ; afterwards opiates in fmall dofes, and the bark. Warm 

 bath frequently ufed. The fleam of warm water with a little 

 vinegar in it may be inhaled twice a day. Thirty drops of fatu- 

 rated tincture of digitalis puerpurea, purple foxglove, were giv- 

 en twice a day to a lady, feventy years of age, in this difeafe, 

 with great and almofl immediate -advantage. I have fmce giv- 

 en from five to ten drops twice a day to two children, with alib 

 great apparent advantage. See Art. IV. 2. 3. 7. Arfenic 

 has lately been recommended in the hooping cough* See Art. 

 IV. 2. 6. 9. And externally a folution of 20 grains of emetic 

 tartar, antimonium tartarifatum, in two ounces of water, to 

 which is to be added one ounce of tincture of cantharides, is rec- 

 ommended, by Dr. Struve of America, to be rubbed very fre- 

 quently on the region of the ftomach. Could the breathing of 

 carbonic acid gas mixed with atmofpheric air be of fervice ? 

 Copious venefetlion, when a difficulty of breathing continues be- 

 tween the fits of coughing ; otherwife the cough and the expec- 

 toration ceafe, and the patient is deltroyed. Ulcers of the lungs 

 fometimes fupervene, and the phthifis nulmonalis in a few 

 weeks terminates in death. Where the cough continues after 

 fome weeks without much of the hooping, and a fenfitive fever 

 daily fupervenes, fo as to referable hectic fever from ulcers of 

 the lungs ; change of air for a week or fortnight als as a charm, 

 and reftores the patient beyond the hopes of the phyfician. 



Young children fhouldlie with their heads and fhoulders raif- 

 ed j and mould be conftantly watched day and night j that when 

 the cough occurs, they may be held up eafily, fo as to ftand upon 

 theirfeet bending a little forwards ; or nicely Supported in that pof- 

 ture which they feem to put themfelves into. Abo w of whalebone, 

 about the fize of the bow of a key, is very ufcful to extract the 

 phlegm out of the mouths of infants at the time of their coughing ; 

 as a handkerchief, if applied at the time of their quick inspirations 

 after long holding their breath is dangerous, and may fuffbcate 

 he patient in an inftant, as I believe has fome times happened.
