8. PertuJJls. Tuilis convulfiva. Chin-cough refembles pe- 

 ripneumonia fuperficialis in its confifting in an inflammation of 

 the membrane which lines the air-veifels of the lungs ; but dif- 

 fers in the circumftance of its being contagious j and is on that 

 account of very long duration ; as the whole of the lungs arc 

 probably riot infecled at the fame time, but the contagious in- 

 flammation continues gradually to creep on the membrane. It 

 may in this refpedl: be compared to the ulcers in the pulmonary 

 confumption ; but it differs in this, that in chin-cough fome 

 branches of the bronchia heal, as others become inflamed. 



This complaint is not ufually clafled amongft febrile diforders, 

 but a fenfitive fever may generally be perceived to attend it du- 

 ring fome part of the day, efpecially in weak patients. And a 

 peripneumony very frequently fupervenes, and deftroys great 

 numbers of children, except the lancet or four or fix leeches be 

 immediately and repeatedly ufed. When the child has perma- 

 nent difficulty of breathing, which continues between the cough- 

 ing fits ; unlefs blood be taken from it, it dies in two, three, or 

 four days of the inflammation of the lungs. During this perma- 

 nent difficulty of breathing, the hooping cough abates, or 

 quite ceafes, and returns again after once or twice bleeding \ 

 which is then a good fymptom, as the child now poiTeffing the 

 power to cough (hews the difficulty of breathing to be abated. 

 I dwell longer upon this, becaufe many lofe their lives from the 

 difficulty there is in bleeding young children ; where the apoth- 

 ecary is old or clumfy, or is not furnilhed with a very fharp and 

 fine pointed lancet. In this diftreffing fituation the application 

 of four leeches to one of the child's legs, the wounds made by 

 which mould continue to bleed an hour or two, is a fuccedane^ 

 um j and faves the patient, if repeated once or twice, according 

 to the difficulty of the refpiration. 



The chin-cough feems to refemble the gonorrhoea venerea in 

 feveral circumftances. They are both received by infection, are 

 both difeafes of the mucous membrane, are both generally cured 

 in four or fix weeks without medicine. If ulcers in the cellular 

 membrane under the mucous membrane occur, they are of a 

 phagedenic kind, and deftroy the patient in both difeafes, if no 

 medicine be adminiftered. 



Hence the cure mould be fimilar in both thefe difeafes , firft 

 general evacuations and diluents, then, after a week or two, I 

 have believed the following pills of great advantage, The dofe
