22 DISEASES CLASS I. 1. 2. 7. 



M. M. Cool air, diluents, warm bath, evacuations. 



7. Catarrhus calidus. Warm catarrh. Consists in an in- 

 creased secretion of mucus from the nostrils without inflamma- 

 tion. This disease, which is called a cold in the head, is fre- 

 quently produced by cold air acting for some time on the mem- 

 branes, which line the nostrils, as it passes to the lungs in respi- 

 ration. Whence a torpor of the action of the mucous glands 

 is first introduced, as in Class I. 2. 3. 3. and an orgasm or in- 

 creased action succeeds in consequence. Afterwards this orgasm 

 and torpor are liable to alternate with each other for some time 

 like the cold and hot fits of ague, attended with deficient or exu- 

 berant secretion of mucus in the nostrils. 



At other times it arises from reverse sympathy with some ex- 

 tensive parts of the skin, which have been exposed too long to 

 cold, as of the head or feet. In consequence of the torpor of 

 these cutaneous capillaries those of the mucous membranes of the 

 nostrils act with greater energy by reverse sympathy; and thence 

 secrete more mucus from the blood. At the same time the ab- 

 sorbents, acting also with greater energy by their reverse sym- 

 pathy with those of some distant part of the skin, absorb the 

 thinner parts of the mucus more hastily; whence the mucus is 

 both thicker and in greater quantity. Other curious circumstan- 

 ces attend this disease; the membrane becomes at times so thick- 

 ened by its increased action in secreting the mucus, that the pa- 

 tient cannot breathe through his nostrils. In this situation, if he 

 warms his whole skin suddenly by fire or bed-clothes, or by 

 drinking warm tea, the increased action of the membrane ceases 

 by its reverse sympathy with the skin; or by the retraction of the 

 sensorial power to other parts of the system; and the patient can 

 breathe again through the nostrils. The same sometimes occurs 

 for a time on going into the cold air by the deduction of heat from 

 the mucous membrane, and its consequent inactivity or torpor. 

 Similar to this when the face and breast have been very hot and 

 red, previous to the eruption of the small-pox by inoculation, and 

 that even when exposed to cool air, I have observed the feet have 

 been cold; till on covering them with warm flannel, as the feet 

 have become warm, the face has cooled. See XXXV. 1. 3. 

 Class II. 1. 3. 5. IV. 2. 2. 10. IV. 1.1.5. 



M. M. Evacuations, abstinence, oil externally on the nose, 

 warm diluent fluids, warm shoes, warm night-cap. 



8. Expectoratio calida. Warm expectoration consists of the 

 increased secretion of mucus from the membrane, which lines 

 the bronchiae, or air-cells of the lungs, without inflammation. 

 This increased mucus is ejected by the action of coughing, and
