1. In considering the column fx it will be seen that the intro- 

 duction of CH 2 into the compound produces an increase in the 

 molecular magnetism which is almost constant, and the mean value 

 of which is -1640. 



2. If the chemical formula of a body is at the same time to 

 indicate its specific magnetism, we can establish the following- 

 equations : — 



16CH 3 + 17HO= 32CH 3 HO, 



150H 3 -|-127I =1420H 3 I, 



29C 2 H 5 + 17HO=46C 2 H 5 HO, 

 58 C 2 H 5 + 32 S = 90 (C 2 H 5 ) 2 S, &c. 



The molecular magnetism of the entire body is thus equal to the 

 sum of the partial magnetisms of the alcohol radical and of the 

 other parts of the compound. 



3. In these compounds, HO, I, Br, and S have the same specific 

 magnetism, the mean value of which is — 44*3. 



4. On the other hand, it is strange that CI has a different specific 

 magnetism of about — 61 ; it must, however, be remarked that only 

 a single chloride was examined. It is nevertheless interesting 

 that the two acetates give for the radical of acetic acid nearly the 

 same magnetism as that found for CI — that is, — 63 in the mean. 

 There is possibly a group of radicals with the specific magnetism 

 about —62. 



5. Propylic alcohol and isopropylic alcohol show exactly the 

 same value ; and isobutyric alcohol gives the value which is calcu- 

 lated for butylic alcohol from the law (1). So far as examined, 

 the alcohol radicals possess the same magnetism in their isomers. 



6. The magnetism of the alcohol radicals is made up of the 

 atomic magnetisms of the C and H, so that, as in (1), the following 

 equations may be made : — 



15CH 3 = 12C + 3H, 

 29C 2 H 5 =24C + 5H, &c. 



If we calculate from this C and H, we get for H the rather large 

 value —780*5, while C is only —5' 6. The latter number is nume- 

 rically so small in comparison with —780, that no importance can 

 be assigned to it. The equations are just as well satisfied by C=0 

 and H= 807-6. 



The investigations are being continued, and the influence of 

 temperature will especially be taken into account. — From an Abstract,
