2 THE FLUIDS. 



fication, and that those fluids only should be called organised 

 which contain in them, as essential, or at all events as con- 

 stant constituents, certain solid and organised particles, while 

 those liquids which are compounded of no such solid matters, 

 as essential portions of them, should be termed unorganised. 



In the first category, the lymph, chyle, blood, mucus, as 

 normal, and pus, as an abnormal fluid, would find their places 

 together with the milk and semen. The fluids of this class, 

 it will be seen, belong especially to nutrition and reproduc- 

 tion, and admit also, naturally, of arrangement into two 

 series ; in the first, those fluids which are concerned in the 

 nutrition and growth of the species itself would be comprised, 

 as lymph, chyle, and blood ; and in the second, those liquids 

 which appertain to the reproduction, nutrition, and growth 

 of the new species, as the milk and semen, would be ad- 

 mitted. 



In the second category, viz. that of unorganised fluids, 

 the perspirable fluid, the saliva, the bile, and the urine, as well 

 as probably the fluid of the pancreas, and of certain other 

 glandular organs would be found. 



This arrangement of the fluids of the human body might 

 be represented tabularly, thus 



FLUIDS. 



Organised. Unorganised.

Normal : 



Perspirable fluid. 

 Saliva.

Pancreatic fluid (?)

Lymph.

 Mucus. 

 Abnormal : 



Pus. 

 2d series. 



Milk. 

 Semen. 



If the terms ORGANISED and UNORGANISED be objected to, 

 the words COMPOUND and SIMPLE might take their places, 

 and would well express the distinction which characterises 

 the two series of fluids, the former appellation being applied 

 to those fluids which are compounded of both a solid and a 

 fluid element, and the latter to those which do not possess 

 this double constitution.
