Lymph and Lymphoid Fluids. 



THAT the term lymph is of very frequent occurrence in 

 the literature of the sciences, constituting the foundation 

 on which practical medicine, surgery, and obstetrics rest,

 that it is in continual use by the initiated in the practice 

 of one and all departments of the medical profession is a 

 matter of everyday knowledge and experience. 



Lymph may, therefore, be regarded as a fluid of constant 

 occurrence in the scientific and practical experience of all 

 in any way concerned with the study and application of 

 such subjects to the daily wants of men and animals, and as 

 a subject many-sided in the range of its practical bearings 

 on the application of preventive, curative, and ameliorative 

 means and principles. Its earliest appearance as a formed, 

 organic fluid, we may take it, is in the form of chyle. 

 After, or when it has been thus far elaborated, and, we 

 may assume, partially vitalised, by the gastric, and subse- 

 quently, as chyle, by the intestinal, mucosa, and the 

 mesenteric glands, it is prepared for physical admixture 

 and chemico-physiological union with the blood proper for 

 further organisation and vitalisation. At this stage it 

 becomes, from that admixture and union and its subse- 

 quent subjection to pulmonary aeration, the vehicle as 

 well as the material of the nutritive plasma of the arterial 

 blood either as its liquor sanguinis, which is the typical
