in its general appearance, and probably in its office of assisting di- 

 gestion, by preventing the fermentation of the aliment; as would 

 appear by the experiments of Pringle and Macbride; there is 

 reason to suspect, that a sympathy may exist between the sali- 

 vary and pancreatic glands; and that the perpetual stimulus of 

 the former by tobacco might in process of time injure the latter. 

 See Tobacco, Article III. 2. 2. 



8. Torpor renis. Immobility or paralysis of the kidneys is 

 probably frequently mistaken for gravel in them. Several, who 

 have lived rather intemperately in respect to fermented or spi- 

 rituous liquors, become suddenly seized about the age of sixty, or 

 later, with a total stoppage of urine; though they have previ- 

 ously had no symptoms of gravel. In these- cases there is no 

 water in the bladder; as is known by the introduction of the 

 catheter, of which those made of elastic gum are said to be pre- 

 ferable to metallic ones; or it may generally be known by the 

 shape of the abdomen, either by the eye or hand. Bougies and 

 catheters of elastic gum are sold at No. 37, Red-Lion street.

M. M. Electric shocks, warm bath. Emetics. See calcu- 

 lus renis, Class I. 1. 3. 9. When no gravel has been previously 

 observed, and the patient has been a wine-drinker rather than 

 an ale-drinker, the case is generally owing to inirritability of the 

 tubuli uriniferi, and is frequently fatal. See Class I. 2. 4. 20. 



9. Punctce mucosw vultfis. Mucous spots on the face. These 

 are owing to the inactivity of the excretory ducts of the mucous 

 glands; the thinner part of this secretion exhales, and the remain- 

 der becomes inspissated, and lodges in the duct; the extremity 

 of which becomes black by exposure to the air. 



M. M. They may be pressed out by the finger-nails. Warm 

 water. Ether frequently applied. Blister on the part? 



10. Maculae, cutis fulvw. Morphew or freckles. Tawny' 

 blotches on the skin of the face and arms of elderly people, and 

 frequently on their legs after slight erysipelas. The freckles on 

 the face of younger people, who have red hair, seem to be a simi- 

 lar production, and seem all to be caused by the coalescence of 

 the minute arteries or capillaries of the part. In a scar after a 

 wound the integument is only opaque; but in these blotches, 

 which are called morphew and freckles, the small vessels seem to 

 have become inactive with some of the serum of the blood stag- 

 nating in them, from whence their colour. See Class HI. 1.2. 12. 



M. M. Warm bathing. A blister on the part? 



11. Canilies. Grey hair. In the injection of the vessels of 

 animals for the purposes of anatomical preparations, the colour of 

 the injected fluid will not pass into many very minute vessels:
