1 14 DISEASES CLASS I. 2. 4. 11. 



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

 more robust, by gentle constant exercise in the open air, flesh 

 diet, small bear at meals with one glass of wine, regular hours 

 of rest and rising, and of meals. The clothing about the head 

 should be warmer during sleep than in the day; because at that 

 time people are more liable to take cold; that is the membranous 

 parts of it are more liable to become torpid; as explained in Sect. 

 XVIII. 15. In respect to medicine, two drams of valerian 

 root in powder three or four times a day are recommended by 

 Fordyce. The bark. Steel in moderate quantities. An eme- 

 tic. A blister. Opium, half a grain twice a day. Decayed 

 teeth should be extracted, particularly such as either ache or are 

 useless. Cold bath between 60 and 70 degrees of heat. Warm 

 bath of 94 or 98 degrees every day for half an hour during a 

 month. See Class IV. 2. 2. 7. and 8. and IV. 2. 4. 3. 



A solution of arsenic, about the sixteenth part of a grain, is re- 

 ported to have great effect in this disease. It should be taken 

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

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

 of tasteless ague-drops: but a more certain method of ascer- 

 taining the quantity is delivered in the preceding Materia Medi- 

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

 Atropa Belladonna are recommended in some foreign publication 

 to be repeated once in two days, and are said to be successful in 

 the dolor faciei, or hemicrania idiopathica. 



Cephalcea Somniosa. Head-ache frpm sleep. This disease 

 has not been described, I believe, by any writer, though it affects 

 some invalids for years. After some hours of sleep the patients 

 are afflicted with distressing dreams, and awake with pain of the 

 head, which continues for some time after they awake; and so 

 circumstanced furnishes the diagnostic symptom of this species 

 of cephalaea. 



The paroxysms or repetitions of many diseases are liable to 

 commence in sleep, some from the increase of sensibility during 

 sleep, as explained in Sect. XVIII. 5. and 15. of the first part of 

 this work, as those of some epilepsies, of some asthmas, and of 

 the gout. Other diseases are liable to return during sleep from 

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

 sorption, as in somnus interruptus, Class I. 2. 1. 3. and in in- 

 cubus, or night-mare, Class III. 2. 1. 13. and in haemoptoe 

 venosa, Class I. 2. 1. 9. and probably in the humoral asthma ? 

 Class II. 1. 1. 8. 



The cephalaea somniosa I suspect to bear the same analogy to 

 the hydrocephalus intemus, as I believe the asthma humorale to 

 bear to the anasarca pulmonum; and to consist in this circum-
