egestive systems theirs, in accordance with the general and 

 particular local conditions involved. It, therefore, be- 

 comes a matter of the greatest diagnostic importance to 

 locate the position of the circulatory stasis in order to be 

 able to prescribe suitable means for its removal, and the 

 restoration of the onward progression of the circulating 

 ingestive, metabolic, and egestive materials, and the re- 

 gainment of the physiological circulatory equilibrium. 

 Having located the position of the circulatory stasis, it 

 will become possible to indicate a treatment, founded on 

 the recognition of the great principle referred to, with 

 greater scientific precision, and a greater hope of a suc- 

 cessful result, than can be possible on lines largely 

 dictated by the results of empirical experience, somewhat 

 in-coordinated observations, and individual manners of 

 deduction. 



Every stage of the entire intra-corporeal circulation 

 must, therefore, be "passed in review" as we proceed to 

 discover the flaws in its course, and we feel assured that 

 the labour of the reviewer will be amply repaid by a more 

 or less full and definite appreciation of the morbid in- 

 fluence, or influences, at work in the production, character, 

 and intrinsic nature of the morbid condition, and by the 

 possible nay probable discovery of the lines on which 

 that morbid condition can be rectified. On the accom- 

 plishment of this absolutely necessary preliminary diagnostic 

 process, with, it is to be hoped, the detection of the site, 

 or sites, of the circulatory derangement, amid the pan- 

 circulatory activities of the diseased subject, we shall 

 obtain the possession of a vantage ground from which to 

 view the pathological results effected by the particular 

 disease, to note the sequence of its morbid events, and 

 to see our way working backwards or forwards from that 

 site, or these sites, as the circumstances of the individual 

 case require to re-establish the arrested, perverted, or 

 deranged current of morbid circulatory phenomena and 

 contingent altered material conditions, and thereby be 

 enabled to cure or ameliorate the disease in question. 

 Accordingly, therefore, as the morbid phenomena are 

 observable in the ingestive, metabolic, or egestive circu- 

 latory areas, we must be prepared to lay our plans for the
