acetate and glacial acetic acid ; the reaction commenced at 100°, proceeded rapidly at 
120°, but to ensure a complete decomposition it was found necessary to heat 
to 150°. 
The product consisted of a hexyl acetate and a little hexene, which were readily 
separated by distillation. The acetate possesses the characteristic smell of the acetic 
ethers, and boils at 146 — 150°; it was converted into the alcohol by heating it with 
caustic potash and a little water ; the hexyl alcohol thus formed boiled, after drying it 
over potassium carbonate and removing a little hexene by distillation, at 136 — 140°, 
and smelled like methylbutyl carbinol. It was oxidised in the cold by chromic acid 
solution in the manner described in my last paper. A neutral liquid was thus obtained 
possessing the odour of methylbutyl ketone ; it began to boil at 127°, and the greater 
portion distilled between this temperature and 1 30° ; the thermometer then rose rapidly, 
and the residue had the odour of a compound ether, and consisted, as the following 
experiments show, undoubtedly, of hexyl butyrate. Besides these compounds a very 
small quantity of acids had also been formed which, judging by the smell, consisted of 
acetic acid and butyric acid ; a few drops of dilute soda were sufficient to neutralise 
them. 
The ketone and ether were again mixed and heated with the oxidising mixture, 
which contained twice as much water as in my previous experiments, nearly to the 
boiling point, and the acids converted in the sodium salts, as described in my former 
paper. Two series of experiments were made to ascertain their composition. 
As it appeared very probable that only acetic acid and butyric acid were formed, 
the sodium salts were distilled with sulphuric acid and a little water, and the distillate 
after diluting with much water repeatedly distilled, the first distillates and the residues 
being kept separately. The first distillate and the last residue were then converted 
into the silver-salts by boiling them with silver carbonate, and the silver determined by 
ignition. 
0-3241 of salt from the first distillate, crystallising in small needles, gave 
0’1793 silver. 
Calculated for silver butyrate. Found.

0-2647 of salt from the last residue, forming larger glistening needles, gave 
0*1690 silver.

The intermediate distillates were again mixed and neutralised with sodium car- 
bonate. The acids were liberated from this mixture in four fractions by the method 
formerly described : —
