Class II. i. 3. $. 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 neceffary to keep 

 the bowels open, 



M. M. Amimonial vomits frequently repeated. 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 fteam 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 almoft immediate advantage. I have fmce giv- 

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

 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 flomach. Could the breathing of 

 carbonic acid gas mixed with atmofpheric air be of fei vice ? 

 Copious venefection, when a difficulty of breathing continues be- 

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

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

 fometimes fupervene, and the phthifis pulmonalis m a few 

 weeks terminates in death. Where the cough contifmes after 

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

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

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

 and reftores the patient beyond the hopes of the phyfician. 



Young children mould lie with their heads and (boulders raif- 

 ed ; and fhould be constantly watched day and night ; that when 

 the cough occurs, they may be held tip eafily, fo as to Hand upon 

 their feet bending a little forwards ; of nicely i up ported in that pof- 

 ture which they feem to put themfelves into. A bow of whalebone, 

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

 phlegm out of the mouths of ire nts at the time of their coughing ; 

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

 after long holding their breath is dangerous, and may fuftbeate 

 he patient in an inftant. as I believe has fometimeshappened.
