ZOOGENY. 401 



2333. The embryonic intestine is the vitellus or 

 yelk. 



2334. The embryonic integument is the amnion. 



2335. The embryonic vascular system is the chorion. 



2336. The embryonic sexual system is the allantois. 

 The above propositions can only be perfectly developed in 

 the physiology. 



b. VASCULAR ORGANS OF THE SEX. 



2337. The haematopoietic or blood-preparing vascular 

 system is the lung; the blood-destroying, exsecernent 

 vascular system is the kidneys. The kidneys are the 

 lung reversed. The liver decomposes the venous, the 

 kidneys the arteriose blood. 



2338. The kidneys are the individualized vascular 

 system of the sex, as the liver is that for digestion. They 

 accord with the liver in their glandular structure, in the 

 renal pelvis, which is like the gall-bladder, in the ureters 

 that resemble the biliary ducts, and lastly, in the general 

 signification of the urine as a product, wherein the whole 

 organism, the whole blood- system has been excreted, 

 like the bile, in which the venous blood undergoes the 

 same process. 



2339. Every disturbance of the digestive function 

 acts in a striking and very direct manner upon the urine. 

 The jaundice is apparent in urine ; and what else is 

 diabetes than a malady analogous to diseases of the 

 liver? In urine we recognize what the bile has done 

 with the food; the urine is the fluid nutritive system, 

 and consequently the fluid organism " in toto;" the sexual 

 blood, or sexual bile. 



2340. The urine is the purest mirror or reflex of the 

 bodily condition, and hence ourology or the doctrine of 

 urine is of the most universal importance in semeiotics or 

 symptomatic pathology : the ureters correspond to the 

 tracheal branches or bronchi ; thus, the urinary bladder 

 to the trachea ; the urethra to the larynx. 



2341. In many animals the ureters open directly into 

 the cloaca, as in many Fishes, Reptiles.
