1 6 PHYSIC 



incompleteness, or disease, must exist the physiological 

 giving place to the pathological circulatory process, health 

 giving place to disease, as cause leads to effect, with the 

 inevitableness of "law and order," without a break of 

 continuity or breach of sequence of the circulatory chain 

 of movements and events. On this chain of circulatory 

 movements and events, moreover, the whole phenomena 

 of life, healthy and diseased alike, from the cradle to the 

 grave, are grouped in successional order, the one deter- 

 mining the other, as its various links are run out from its 

 opening to its close once more compelling the expression : 

 circulatio circulationum omnia circulatio. 



It would be easy to cite here diseases illustrative of the 

 various classes embraced in the orders of ingestive, meta- 

 bolic, and egestive, but suffice it to say that we have 

 endeavoured to do this, although somewhat irregularly, in 

 the clinical extracts relating to particular or individual 

 diseases. As types, however, of the three orders of 

 disease due to pathological conditions of the three great 

 circulatory divisions, ingestive, metabolic, and egestive, 

 we would instance tabes mesenterica, gangrene, and 

 leprosy as respectively displaying the attributes of stasis, 

 or arrestment, of circulatory movement, more or less com- 

 plete, of the materials transmitted through the respective 

 vasculatures. These three typical affections, thus tabu- 

 lated together, respectively represent circulatory break- 

 downs within the area of ingestive, metabolic, and egestive 

 distribution, and are characterised respectively by struc- 

 tural phenomena of deprivation of nutritive pabulum, 

 mal- or non-nutritive disposal of tissue protoplasm^ and 

 retention or non-excretion and non-exfoliation of effete 

 or residual tissue debris. 



The lines of treatment to be followed in such affections 

 must, therefore, naturally follow or flow from an exact 

 appreciation of the etiological factors at work in their 

 evolution, and the ability to adopt the means at present 

 available or at our disposal for effecting the removal of 

 the circulatory stasis and its dependent pathological pheno- 

 mena, or to supplement these by inventing new or im- 

 proved means to meet the indications of the particular 

 case, and so to aid the work of placing the knowledge of
