fluid having very nearly the specific gravity and boiling point of 
Plantamour’s oil, but the irritating action of its vapour was scarcely 
diminished. It gave likewise the solid compound when mixed with 
aniline, so that there is no doubt about the identity of the bodies. 
I distilled in the sunshine the mixture given above, in the hope that 
the product might be only hexachlorinated acetone, but a violent 
explosion put an end to the experiment. The mixture obtained in 
this way is evidently the same as that Plantamour got by acting 
with chlorine on a citrate. 
The similar oil got from citric acid, oxide of manganese, and 
hydrochloric acid, had only a specific gravity of 1*50 and a portion 
boils even below 212°, but the greater part seems to be pentachlo- 
rinated acetone. From the low boiling point of some of the fractions-, 
it may be questioned whether these bodies are all chlorinated 
acetones. 
The action of chlorochronic acid is too violent, and I have not 
been able to find a better mode of preparing the oil than the slow 
action of chlorine in the sunshine, which gives it pure without any 
trouble. 
The pentachlorinated acetone decomposes with aniline in a similar 
manner with the body described, giving what is probably bichlora- 
cetanilide. 
5. Notice of a Panoramic Sketch of Kashmir, recently received 
from India. By Professor C. Piaazi Smyth. 
A recent panoramic topographical view of the interesting region 
of Kashmir having been just communicated to me by my friend, 
Mr Boger Montgomerie, Advocate, I have found it so remarkably 
well executed, in its almost photographic representation of natural 
features of hill and plain, that I have obtained his leave to present 
it to the ftoyal Society, accompanying the presentation with the 
following few particulars, abstracted from MS. reports. 
The view in question is by Captain Montgomerie, B.E., who, 
under the general direction of Col. A. Scott Waugh, the Director 
of the Indian Trigonometrical Survey, has been constantly at work 
in Kashmir and Thibet since 1855, and with such energy and
