plete examination. All of the temperatures by which these frac- 

 tions are distinguished are subject to correction due to the press- 

 ure being reduced by 100 mm. 



The following analyses were made of these respective fractions : 



Fraction B. 173°— 177°: 



I. Amount taken = .3170 g; H2O obtained =.2205; CO2 obtained = .6300; H =.0245; 

 C = .1718 ;p. e. H = 7.73 ; p. c. C = 54.19. 



II. Amount taken = .3202; H2O obtained = .2547; CO2 obtained = .6336; H = .0283; 

 C == .1728 ; p. c. H = 8.83 ; p. e, = 53.94. 



III. Amount taken = .4181; H2O obtained = .3287; CO2 obtained = .8268; H = .0365; 

 C = .2255; p. e. H = 8.73; p. c. C= 53.93. 



IV. Amount taken = .2785; silver chloride obtained = .3139; chlorine = .07758; 

 p. c. CI = 27.85. 



V. Amount taken = .2750; silver chloride obtained = .3043; chlorine = .07513; 

 p. c. 01 = 23.03. 



Fraction C, 177°— 185°: 



VI. Amount taken = .3259; H2O obtained = .2575; CO2 obtained = .6544; H = .0286; 

 C = .1785 ; p. c. H = 8.78 ; p. e.C = 54.77. 



Fraction T>, 185°— 200°: 



VII. Amount taken = .2642; H2O obtained = .2087; CO2 obtained = .5402; H = .0232: 

 C = .1473 ; p. c. H = 8.78 ; p. c. C = 55.79. 



Fraction E, over 200° : 



VJII. Amount taken = .3165; H2O obtained = .2513; CO2 obtained = .6567; H = .0279; 

 C = 1791 ; p. c. H = 8.81 ; p. c. C = 56.27. 



IX. Amount taken = .2260; H2O obtained = .1794; CO2 obtained = .4072; H= .01993; 

 C = .1274; p. e. H = 8.82; p. c. C = 56..38. 



X. Amount taken = .2080; silver chloride obtained = .255; chlorine = .00295 ; 

 p. c. CI = 23.49. 



The ft)llowing table will show how these percentages compare 

 with those calculated for the chlorine compounds which suggest 

 tliemselves as possibly formeol during the reaction : 



It will be observed that while the percentage of hydrogen is 

 about the same throughout the percentage of carbon increases
