2656. The capillary vessels therefore attract the pul- 

 monary blood, separate it, secrete and form new con- 

 stituent parts ; and then, after it has become homonymous, 

 they repel it back again towards the lungs. 



2657. The circulation only subsists through the 

 polarity which exists between lung and capillary vessels, 

 between lung and body, between oxydation and reduc- 

 tion, combination and separation. 



2658. If the intestine and body be the root, the lung 

 the foliage, so is the lymphatic and vascular system the 

 stem, in which the most perfect substances have been 

 formed. In the circulation the matters for the animal 

 systems must have been fully formed, such as for the 

 bones, the lime ; for the muscles, the iron ; for the nerve, 

 the albumen. 



2659. The liver is the principal organ of the circula- 

 tion. There also must one principal preparation of the 

 blood take place. On account of its parallelism with the 

 brain, the condition probably resides in it that conduces 

 to formation of the albumen, namely, of the Indifferent, 

 which is the nutritive matter of the nervous mass. 



2660. In the vegetable sphere of life there are, in addi- 

 tion to the liver, but two mutually distinct excretory 

 organs, namely, the intestine and the skin. 



2661. In the mucous secretion of the intestine the 

 condition, requisite to the formation of phosphate of time 

 for the bones, probably resides. 



2662. In like manner in the formation of the carbonic 

 acid and the water in the integument, the basis for the 

 formation of phosphate of iron for the muscles may 

 reside. In the circulation the intestine would thus be the 

 lime-, the skin the iron-, and the liver the medulla- 

 forming organ. 



2663. The two extremes of the circulation, or intestine 

 and lung, form gelatine and fibrine ; the circulation itself 

 forms the purely animal matter. Out of the integument 

 and lung grows the muscle, from the intestine the bone 

 and gelatine, out of the liver the nerve. Muscle is 

 integument and air, bone is intestine and chyle, brain is
