GENEKAL PATHOLOGY. . 81 



We notice in the pest less marked absence of external heat, 

 comparatively little tendency to the suspension of the de- 

 carbonizing function of the lung-cells ; and while in the intes- 

 tinal canal the follicular structure is equally involved in both 

 maladies, though in a different manner, and except in the 

 rare cases seen in Pest, with discharges of a totally different 

 character ; the congestive process in its earlier stages sug- 

 gests its rationale as well as that of these variations. 



We need not reiterate that we do not seek to build up any 

 theory of identity or analogy except that which is necessi- 

 tated by the common zymotic character which pervades all 

 pestilences. Having given the few points in which their 

 orbital paths find conjunction, we still desire as far as prac- 

 ticable within the narrow compass of a General Eeport to 

 project the direction of their courses in departure. We shall 

 collate two descriptions of such variations from Perigoff, 

 whose recondite observations on cholera accompanied by 

 remarkable illustrations of lesions (also of microscopic re- 

 searches) are to be found in his Anatomie Pathologique, &c. 

 Premising that in the congestive stages of this disease, we 

 are met with deeper blood-tinting than in any of the affec- 

 tions of the human frame, we have before referred to ; we find 

 it necessary to show other manifestations in these stages in 

 the two diseases, between which it is now proposed to mark 

 the difference. Perigoff gives in PI. II, fig. 3, (in a case 

 of death in typhoid stage), the sanguineous coloring of 

 membrane less deeply tinged than others given by him, 

 which on cursory examination would seem to be identical with 

 that described by Smart (p. 32 and PI. III). Sanguineous 

 effusion upon the mucous membrane in dots occurs also 

 in simple cholera ; and when multiplied in an aggravated case 

 presents an appearance of dark ecchymosis, bordering upon 

 what is elsewhere described by Perigoff, as the incipient stage 

 of mortification. His PI. Y, A, ^g, 3, gives a view of 

 the sigmoid flexure of the colon in the transition from the 

 algid to the typhoid stage which bears a closer resem- 

 blance to the inoculated cases in Pis. VI and YII (pp. 28 

 and 30). You can easily see in all of Smart's drawings
