by carbonic acid. The phenol is readily soluble in acetic 
acid, in ether, alcohol, chloroform and similar organic 
solvents. From the results so far obtained this phenol 
appears to be new; if on further investigation this is found 
to be the case, then the name Callitrol is proposed for it. 
The somewhat dark coloured alkaline solution, after 
removal of the phenol, was acidified, when a dark coloured 
oil separated. This was of an acid nature, was less viscid 
than the phenol, did not distil with steam, and did not 
crystallise. It will eventually be further investigated. 
The volatile acids of the esters of the wood oil were only 
present in very small amount. On distilling these over, 
the odour of butyric acid was most marked. Acetic acid 
was also determined to be present. The barium salt was 
prepared in the usual way, and 0°1356 gram. of this gave 
0°1116 gram. Ba SO,, = 82°3%. From this determination 
there was in the salt 46°17 barium acetate, and 53°83? 
barium butyrate. The free acids obtained, however, were 
not sufficient to meet the requirements of the alcohol of the 
ester, judged from the saponification number. 
Bark.—The most characteristic feature of the bark is the 
very large number and size of resin cells distributed 
throughout the entire bark, both cortex and bast. Macro- 
scopically they appear, in a freshly transverse cut of the 
mass, aS SO many concentric rings, being more pronounced 
in the darker outer bark or cortex, where after the oil of 
the cell has been volatilised or removed, resin or sandarac 
as it is called, remains as a white solid, filling the cells and 
giving the effect of tangential parallel bands or rather rows. 
In the bast or inner bark the cell content is in a liquid 
condition, and on a cut being made into fresh specimens 
there flows at once a liquid, which however indurates into 
beads or tears as soon as the volatile portion has evaporated 
or volatilised.
