206 EXAMINATION OF A NAPHTHA FROM LIME-SOAP. 
cally characterized by the presence of the olefiant series of hydro-carbons, that is, the 
lower series of C, H,. A recent examination by A. Wurtz,’ of the naphtha obtained 
by distilling a mixture of amyl-alcohol and chloride of zinc, goes to show that in this case 
the olefiant series is accompanied by that series of hydrides the several members of 
which boil at 0°, 30°, 60°, 120°, and 150°. We have proposed to ourselves to re-examine 
this naphtha from amyl-alcohol at an early day, for the purpose of proving whether or 
no it contains also members of the other series of hydrides (Schorlemmer’s) which 
boil at 8°, 38°, 68°, 98°, and 128°, as well as for the sake of obtaining the paramylene 
compounds, which we desire to compare with some of the members of our higher series

As has been stated in the text above, the quantity of liquid contained in each of the 
heaps was roughly measured. On summing up these several amounts it appeared that 
there was altogether a total of nearly 6400 ¢. ¢. of liquid. Of this amount about 0.8% 
consisted of amylene and hydride of amyl. 
3.94, of Caproylene. 
2.84, of Hydride of Caproyl. 
3.1% of Benzole. 
4.7% of Ginanthylene. . 
7.6% of Hydrate of Ginanthyl. 
6.9% of Toluole. 
12.54, of Caprylene and Hydride of Capryl. 
13.34, of Xylole. - 
7.8% of Pelargonene. 
23.5% of Isocumole and Rutylene. . 
10.2% of Margarylene. 
3.1% of Laurylene. 
With regard to this table, it must be understood that it refers only to the quantities 
of liquid contained in the actual heaps, and does not include the numerous small frac- 
tions lying between the heaps. It is offered merely as an approximative indication of 
the relative proportions in which the several hydro-carbons were obtained. In the pres- 
ent condition of chemical science there can be of course no thought of attempting the 
quantitative analysis of a crude naphtha like the one now under consideration. In- 
deed, it has been to ourselves a matter of surprise and gratulation that we have been 
able successfully to effect the qualitative separation of the hydro-carbons from a mix- 
ture so extremely complex as this. The actual isolation of fifteen or sixteen different
