‘818. G. E. Moore on the Wax of the Myrica cerifera. 
The products obtained from each of the above mentioned lead . 
precipitates were severally subjected to repeated crystalliza 
m alcohol until the fusing point of the crystals stood unaltered 
by further treatment. From each fraction an acid was thus pro- 
eured which fused at 62° C., and agreed in all respects with pal- 
mitic acid. The first three fractions consisted almost entirely of 
this substance and it was present in considerable quantity even 
in the ninth fraction. . 
The filtrates from the crystallization of the 7th and 9th frac- 
tions were then mixed and subjected to recrystallization. A crop 
of crystals thus obtained likewise fused at 62° C. The new fil 
wet were then mingled and crystallized again with the same 
results : 
The concentrated mother liquors from which nearl 
palmitic acid had thus been separated, were now eva 
nearly to dryness, and the mass saponified to destroy the 
formed by prolonged contact with alcohol. The soap 
com by acids, the precipitate dissolved in alcohol, th 
hanes until a slight crop of crystals formed on coolin 
fluid poured off from these was again evaporated until a depos 
ensued on cooling, and this process was repeated until the crys 
tals thus formed exhibited a constant fusing point, viz. 49 
It thus appears that lawric acid is an ingredient of this wax. | - 
10th fraction which was fluid at ordinary temperatures was found 
by similar treatment to consist almost entirely of laurie ether 
formed by prolonged contact with alcohol. . 
About one pound of the crude fatty acids was repeatedly agt 
tated with small quantities of boiling alcohol until the fusing 
omy of the portion undissolved, remained constant at 62 re 
e several alcoholic solutions thus obtained were then mix 
and evaporated to the point at which crystals formed on cooling, 
the whole allowed to cool to the ordinary atmospheric tempe™ 
ture, the crystals thus formed removed, and the process Te aa
