broth without salt in it. Boiled onions. One grain of calomel 

 everv night for a week. From five drops to ten of tincture of 

 opium at six every night, when the patient becomes weak. 

 Digitalis? See Class II. 1. 6. 7. 



8. Pertussis. Tussis convulsiva. Chin-cough resembles pe- 

 ripnejmonia superficial in its consisting in an inflammation of 

 the membrane which lines the air-vessels of the lungs; but differs 

 in the circumstance of its being contagious; and is on that ac- 

 count of very long duration; as the whole of the lungs are pro- 

 bably not infected at the same time, but the contagious inflamma- 

 tion continues gradually to creep on the membrane. It may in 

 this respect be compared to the ulcers in the pulmonary consump- 

 tion; aut it differs in this, that in chin-cough some branches of the 

 bronchia heal, as others become inflamed. 



THs complaint is not usually classed amongst febrile disorders, 

 but a sensitive fever may generally be perceived to attend it dur- 

 ing s(me part of the day, especially in weak patients. And a 

 peripieumony very frequently supervenes, and destroys great 

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

 immeiiately and repeatedly used. When the child has permanent 

 difficulty of breathing, which continues between the coughing 

 fits, uiless blood be taken from it, it dies in two, three, or four 

 days cf the inflammation of the lungs. During this permanent 

 difficuty of breathing, the hooping cough abates, or quite 

 eases and returns again after once or twice bleeding; which 

 is ther a good symptom, as the child now possessing the power 

 to cou^h shews the difficulty of breathing to be abated. I dwell 

 longer upon this, because many lose their lives from the difficulty 

 there ii in bleeding young children; where the apothecary is old 

 or clunsy, or is not furnished with a very sharp and fine pointed 

 lancet In this distressing situation the application of four leeches 

 to one of the child's legs, the wounds made by which should con- 

 tinue b bleed an hour or two, is a succedaneum; and saves the 

 patien, if repeated once or twice, according to the difficulty of 

 the respiration. 



The chin-cough seems to resemble the gonorrhoea venerea in 

 severa circumstances. They are both received by infection, are 

 both dseases of the mucous membrane, are both generally cured 

 in fouior six weeks without medicine. If ulcers in the cellular 

 memb:ane under the mucous membrane occur, they are of a 

 phagetenic kind, and destroy the patient in both diseases, if no 

 mediche be administered. ' 



Herce the cure should be similar in both these diseases; first 

 generti] evacuations and diluents, then, after a week or two, I 

 have believed the following pills of great advantage. The dose
