same effect can be brought about with canthari- 

 dates as with tuberculin. 1 Dixon showed sub- 

 sequently that creatin had a similar effect, 

 Hebra did the same thing for thiosinaniin, and 

 Mosetig for teukrin, and Spiegler has still 

 further added to the list of such substances. 

 To the same class of therapeutic methods be- 

 longs also the intravenous injection of cinnamic 

 acid in human tuberculosis (Landerer). This 

 substance, likewise, seems to act through the 

 excitation of inflammation and so far has ap- 

 peared to afford the best results obtained with 

 any of these compounds. 



Localized hypersemia, such as makes its 

 appearance in consequence of the diminution 

 of the original pressure caused by opening 

 the peritoneum may act favorably ; and cure 

 has in fact been effected in peritoneal tuber- 

 culosis by means of laparotomy. Acting on 

 this conception Bier has recommended pro- 

 ducing artificial hyperaemia by the use of 

 bandages in cases of tuberculosis of the limbs. 

 We must assign to the same class of phenom- 

 ena the fact that, according to Rokitansky, 

 tuberculosis often sets in when an anaemic 

 condition of the lungs prevails as the result of 



1 Outside of the determination of this fact little consideration has 

 been devoted to the question whether these salts contribute as 

 much as or more than tuberculin to the cure of tuberculosis in man.
