Stases, therefore, of all degrees in the vasculatures and 

 circulatory inter-spaces, from the largest to the most 

 minute known to anatomy and histology, are the causes 

 of pathological conditions ranging from definite structural 

 new formations or neoplasms to the most minute and 

 ephemeral arrestive circulatory phenomena. 



The occurrence of circulatory stasis, strictly speaking, 

 must apply to, and can only take place, where circulation 

 exists, i.e. usually along definite lines or in the vascu- 

 latures and tissue inter-spaces, in other words, in the 

 canals, ducts, vessels, and inter-communicating channels, 

 where the alimentary, the haemal, the lymph, and the 

 neural materials are conveyed to their respective destina- 

 tions ; it must, at the same time, be recognised that the 

 cells, to which these vasculatures convey their contained 

 materials, and from which they again receive them, must 

 of necessity suffer in some degree from the incidence of 

 the same biological statics and dynamics in their reception, 

 intra-cellular disposal, and return of these materials. It 

 must, therefore, follow that cell circulatory stasis must also 

 be regarded as a causative influence in the incidence of 

 those diseases due to the arrest of movement of the 

 materials concerned in the vital processes of metabolism 

 and physiological hygiene. A cell or a group of cells 

 may thus be the centre or the point from which many 

 of the diseases referred to are to be traced, and, conse- 

 quently, may, if discoverable, be made the stepping stones 

 to the obtainment of indications for successful treatment. 



Circulatory stasis, therefore, however minute or limited, 

 if associated with perturbed formative physiological 

 activity, may lead by pathological continuity to the pro- 

 duction of new growths and strange forms of tissue evolu- 

 tion, both innocent and malignant, without, in the first 

 instance, the presence of other than normal conditions and 

 physiological influences, these latter changing by degrees 

 into pathological by regular and continuous formative 

 sequence the same physiological materio-dynamic expen- 

 diture, as dispensed by pathological means, ultimately 

 leading to the production of foreign and alien results.
