1 14 DISEASES Class I. 2. 4. it; 



M. M. The method of cure confifts in rendering the habit 

 more robuft, by gentle conftant exercife in the open air, flefh 

 diet, frriall beer at meals with one glafs of wine, regular hours 

 of reft and rifing, and of meals. The clothing about the head 

 fhould be warmer during fleep than in the day ; becaufe at that 

 time people are more liable to take cold ; that is, the membra- 

 nous parts of it are more liable to become torpid ; as Explained 

 in Sect. XVIII. 15. In refpe£t to medicine, two drams of va- 

 lerian root in powder three or four times a day are recommend- 

 ed by Fordyce. The bark. Steel in moderate quantities. An 

 emetic. A blifter. Opium, half a grain twice a day. Decay- 

 ed teeth fhould be extracted, particularly fuch as either ache* or 

 are ufelefs. Cold bath between 60 and 70 degrees of heat. 

 Warm bath of 94 or 98 degrees every day for half an hour du- 

 ring a month. See Clafs IV. 2. 2. 7. and 3. and IV. 2. 4. 3. 

 A folution of arfenic, about the Sixteenth part of a grain, is re- 

 ported to have great effect in this difeafe. It mould be taken 

 thrice a day, if it produces no griping or ficknefs, for two or 

 three weeks. A medicine of this kind is fold under the name 

 of taflelefs ague-drops ; but a more certain method of afcer- 

 taining the quantity is delivered in the preceding Materia Med- 

 jca, Art. IV. 2. 6. 8. Five grains of the powdered leaves of 

 .Atropa Belladonna are recommended in fome foreign publica- 

 tion to be repeated once in two days, and are faid to be fuccefs- 

 ful in the dolor faciei, or hemicrania idiopathica. 



CephaUa fomniGfa. Head-ach from fleep. This difeafe has 

 not been defcribed,I believe, by any writer, though it affecls fome 

 invalids for years. After fome hours of fleep the patients are 

 r.fHicted with diftreffing dreams, and awake with pain of the 

 head, which continues for fome time after they awake \ and fo 

 circumflanced furnifhes the diagnoflic fymptom of this fpecies of 

 cenhakea. 



The paroxyfms or repetitions of many difeafes are liable to 

 commence in lleep, feme from the increafe of fenfibility during 

 fieep^ as explained in Seel:. XVIII. 5. and 15. of the firft part of 

 this work, as thofe of fome epilepfies, of fome afthmas, and of 

 the gout. Other difeafes are liable to return during fleep from 

 the debility of the pulmonary circulation, or of pulmonary ab- 

 sorption, as in fomnus interruptus, Clafs I. 2. 1. 3. and in in- 

 cubus, or night-mare, Clafs III. 2. 1. 13. and in hremoptoe 

 venofa, Clafs I. 2. 1. 9. and probably in the humoral afthma, 

 Clafs II. 1. 1. 8. 



The cephalrea fomniofa I fufpect to bear the fame analogy to 

 the hydrocephalus interims, as I believe the afthma humorale to 

 bear to the anafarca pulmonum ; and to confift in this circum- 



ftance,
