I have not studied this substance very minutely ; it forms crystalline salts with sul- 
phuric, nitric, oxalic and hydrochloric acids. 
Action of Iodide of Amyl upon Triethylamine. 
The experiment was conducted in a perfectly similar manner, and the results ob- 
tained are perfectly analogous. The action however is by no means as rapid as in the 
preceding cases, the amyl-substances being invariably much more inert than the cor- 
responding terms in the ethyl- and methyl-series. In order to complete the process, it 
is necessary to heat the mixture in sealed tubes for two or three days. The iodide of 
amylotriethylammonium, for this is the new compound, forms remarkably fine crystals, 
which exhibit the fatty lustre and touch peculiar to the amyl-compounds. It is ex- 
tremely soluble in water and alcohol, insoluble in ether. The solutions have the 
bitter taste of quinine. On adding potassa or carbonate of potassa, the iodide sepa- 
rates as an oil, which rapidly shoots into brilliant needles. The salt when slightly 
moist fuses at 100° C. to a clear oily liquid, which becomes solid on cooling and per- 
fect desiccation, and gradually assumes a yellow tint. 
The iodine-determination gave the following result : — 
0'4210 grm. of iodide gave 0‘3310 grm. of iodide of silver.

When boiled with protoxide of silver the base is liberated and dissolves, forming 
an alkaline liquid of extremely bitter taste. The alkaline properties are however less 
marked than in the preceding bases. On evaporation the oxide of amylotriethylam- 
monium remains in form of a syrup, which I have never seen assuming the crystal- 
line form, perhaps because I have not allowed it to stand for a sufficiently long time.
