Micro chemical Studies, The bodies present the following reactions: 



In water, aside from even at high temperature, the body does not 

 disappear. 



In absolute alcohol, even after prolonged immersion, it is resistant. 



In sulphuric ether, it is insoluble. 



In a solution of iodide of potassium, the central part stains an in- 

 tense brovm and the peripheral part golden '^Q^^, 



With Millon*s reagent, if agitated and heated, the central part takes 

 on a marked brick red color and the peripheral part stains a light rose 

 yello./. 



V^ith IUspail*s solution, the central part takes on an intense rose 

 j»oi4l?'j", while the periphery is stained less intensely,. 



Treated with a solution of Tromtner^s reagent (copper-alkaline solution), 

 the body assurces a violet color, and this color becomes more distinct in 

 the central part of the body, 



V/ith nitric acid and ammonia, the body af,sumes a yellow color; with 

 Sudan III, it stains weakly; with osmic acid :Lt becomes light brown; with 

 acetate and chloride of iron and with bichromate of potassivim, the body 

 presents no particular color change; with copper acetate in aqueous solution 

 (after somer days) it shows no coloration. 



Among the reagents thus listed from the reactions obtained through the 

 use of Millon, Haspail, and Trommer*s solutions, there remains no doubt as 

 to the proteinaceous nature of the sub£>tance which forms the central part 

 of the body, and these reactions indicc.te the participation of a substpa^e 

 Similar in nature to the foitaation of tJaa peripher^d part of the body.
