fels of the kidneys, and the abforbents of the bladder, have acted 

 with greater energy. When there is much earthy fediment, it 

 ihews, that the abforbents have acted proportionally ftronger, 

 and have confequently left the urine in a lefs dilute ftate. In 

 this urine the tranfparent fediment or cloud is mucous ; ths 

 opaque fediment is probably coagulable lymph from the blood 

 changed by an animal or chemical procefs. The floating fcum 

 is oil. The angular concretions to the fides of the pot, formed 

 as the urine cools, is microcofmic fait. Does the adhefive blue 

 matter on the fides of the glafs, or the blue circle on it at the 

 edge of the upper furface of the urine, con fill of Prufiian blue ? 



5. Diarrhoea culida. Warm diarrhoea. This fpecies may 

 be divided into three varieties, deduced from their remote caufes, 

 under the names of diarrhoea febrilis, diarrhoea crapulofa, and 

 diarrhoea infantum. The febrile diarrhoea appears at the end 

 of fever-fits, and is erroneouily called critical, like the copious 

 urine, and the fweats \ whereas it arifes from the increafed action 

 of thbfe fecerning organs, which pour their fluids into the intef- 

 tinal canal (as the liver, pancreas, and mucous glands,) contin- 

 uing longer than the increafed action of the mteftinal abforbents. 

 In this diarrhoea there is no appearance of curdled chyle in the 

 ftools, as occurs in cholera. I. 3. 1. 5. 



The diarrhoea crapulofa , or diarrhoea from indigeftion, occurs 

 when too great a quantity of food or liquid has been taken ; 

 which not being completely digelted, ftinmlates the inteftines 

 'like any other extraneous acrid material ; and thus produces an 

 increafe of the fecretions into them of mucus* pancreatic juice, 

 and bile. When the contents of the bowels are (till more ftim- 

 ulant, as when draflic purges, or very putrescent diet, have been 

 taken, a cholera is induced. See Seel. XXIX. 4. 



The diarrhoea infantum, or diarrhoea of infants, is generally 

 owing to too great acidity in their bowels. Milk is found 

 curdled in the ftomachs of all animals, old as well as young, and 

 even of carnivorous ones, as of hawks. (Spallanzani.) And 

 it is the gaftrjc juice of the calf, which is employed to curdle 

 milk in the procefs of making cheefe. Milk is the natural food 

 for children, and mull curdle in their ftomachs previous to di- 

 geftion •, and as this curdling of the milk deftroys a part of the 

 acid juices of the ftcmach, there is no reafon for difcontinuing 

 the ufe of it, though it is occafionally ejected in a curdled ftate. 

 A child of a week old, which had been taken from the breaft of 

 its dying mother, and had by fome uncommon error been fuf- 

 fered to take no food but water-gruel, became fick and griped 

 in twenty-four hours, and was convulfed on the fecond day, and 

 died on the third ! When all young quadrupeds,, as well as« 



children.
