N is determined by Kjeldahl's process and elementary analysis is 

 made in the electrica! owen censtructed by Prof. Ivan Marek in 

 Zagreb. 



The alkaloid Squamarin becomes lipuid at 42" C (uncorrected). 

 The taste of it is Sharp like that of pepper, and it smells Sharp 

 and charasteristical. The extraction of it was made with Soxhlet's 

 apparatus for fat-extraction with ether. After the evaporation of the 

 Solution of Chloroforms there remain very small crystals measuring 

 250 fji — 800 [i in length. 



Besides this alkaloid a resin is isolated with the empirical 

 formula : 



(Cr, //ii 0.,)n 



Lastly the sugar is determined: it is glucose. Also a saponin 

 is isolated, but it was not possible to examine it in detail on acco- 

 unt Ol lack on material. 



Fatty oils that should be in this plant, according to literature, 

 I could not isolate. 



The thing surely deserves more interest, and it will be pos- 

 sible to indicate the final results after a systematical study lasting 

 several years.
