is consequently the purest reflex or pattern of the 

 former. 



2938. The urine is sexual blood, just as the excre- 

 ment is a product of the sexual digestion. The urine is 

 reversed blood. 



."2939. The formation of urine is a retro-formation of 

 the blood into digestive fluid or sap. The urine is blood 

 of the sexual animal which has become chyle. It has both 

 properties in itself. It is discoloured blood, and consists 

 for the greatest part of water and salts, all of which are 

 characters belonging unto chyle. It, however, contains 

 urea, which corresponds to the noblest parts of the blood. 

 This substance, like fibrin e, consists for the greatest part 

 of nitrogen ; it may be called dissolved or decomposed 

 fibrine. It imparts colour to the urine ; it is converted 

 by oxydation into lithic or uric acid, and is precipitated 

 of a red colour analogous to that of the blood-globules. 

 In addition to this, albumen, gelatine, carbonate of 

 lime, and phosphorus, consequently the whole blood, are 

 present in the urine. 



2940. In urea the muscle flows or runs out of the 

 animal, in albumen the nerve, in lime and phosphorus 

 the bone, in gelatine the tegumentary together with the 

 visceral system, lastly, in water the menstruum of the 

 digestion and respiration. 



2941. Thus the urine, just like the blood, is the whole 

 body rendered fluid, but only in a sexual manner, 

 namely, as being hah decomposed. 



2942. So the bile, from its not representing the whole 

 body, does not contain the latter in itself. It properly 

 contains only the excretion of the intestinal process. 



2943. The kidneys stand accordingly opposed without 

 distinction to all the organs, in so far as all of them are 

 affected by the circulation. Their remote sympathy, or 

 if we please, their antagonism, is with the animal 

 systems, or with bone, muscle, and nerve. With the 

 osseous, as being the profoundest system, there is of 

 necessity also a close sympathy. In diseases of bone the 

 bones, as well as the morbid matter, flow away principally
