REPARATORY INFLAMMATION IN ARTERIES. 9 



Siaipsoii (Acupressure as a new hix^mostatic process. Royal 

 Society of Edinburgh, 1859) claimed that the acupressed vessel 

 is closed by adhesive inflammation of its inner walls. 



13oo-douowsky (^Medicinische Zeitschrift (Russia;, 1862) sum- 

 marized the results of experiments upon varicose veins by the 

 declaration that the thrombus formed by injecting into the 

 veins liquor ferri sesquichloridi acts as a foreign body, and can 

 only degenerate ; that the vessel is obliterated at the expense 

 of its Avails. 



Ardreef (Ueber das Blutkorperchen in histologischer Bezie- 

 hung, St. Petersburg, 1862) alHrmed that he liad observed the 

 transition of the red blood-corpuscles into the white, and subse- 

 quently the formation of connective tissue from these. 



Koslowsky (Untersuchung ueber die Strabotomie. St. 

 Petersburg, 1863) and Rindfleisch (Apoplexia cerebri. Arch, 

 d. Heilkd. von Wagner, 1863) confirmed this observation. 



Billroth (AUgem. chirurg. Pathologic und Therapie, 1863), 

 studying the thrombus with the microscope, made observations 

 which he considered to be a demonstration of the truth of Vir- 

 chow's suspicion of the formative activity of the white blood- 

 corpuscle. 



Schmidt (Ueber den Faserstoff und die Ursache seiner Ge- 

 riunung. (Russische) Militiir-Medicin Journal, 1863) contended 

 that the length of time requisite for the formation of a coagulum 

 after ligation depends upon the various conditions affecting the 

 coagulability of the blood. He conceived that a fibrino-plastic 

 substance exists in the vessel walls, and, that after its destruc- 

 tion, by any injury to the walls for instance, it is endued with 

 the capability so to act upon the fibrinogenous substance of the 

 blood as to condition, from the latter, coagulation. 



Janowitsch Tschiansky (Dissertatio, St. Petersburg, 1864) 

 repeated and confirmed the experiment and conclusions of Bog- 



donowsky.
