Lieut. Forry describes the Oogadong and silicious or Phiringi 
beds of coal as follows : 
2. The Oogadong coal (See. Pl. XIX.) occurs in what geologists would 
call the newest floetz trap formation : it consists of pitch-coal, brown coal, 
and a slate coal; it is found in conjunction with iron pyrites beneath 
a stratum of sandstone, &c. similar to that of Syneg Kyong. The 
vein appears to run from east to west, extending from the foot of a 
small hill towards the sea. 
3. The Phéiringué bed is apparently a continuation of the last, 
lying in the same direction, at the distance of two coss, though sepa- 
rated by the sea. It crops out from between layers of a fine greyish 
sandstone, in a small island, one of the ‘‘ Balungahs,” or broken 
islands: the beds are nearly horizontal, dipping slightly towards 
Oogadong. 
Lieut. Founy also alludes to the plentiful supply of coral lime along 
the coast, and in Ramree Island, where there is a loose calcareous 
rock forming !ow hills in the direction of Moira, probably formed from 
the degradation of the coral.—There are mud volcanoes in Ramree as in 
Cheduba*, which spout out abundance of pyrites and kidney iron ore. 
A crater of this kind is pointed out at Oogadong, where scoriaceous 
matter, trap minerals, and basalt shew evidence of more active volcanic 
agency in times past. Petrified wood occurs also near Nagadong.

Transactions of the Batavian Society of Arts and Sciences, Vol. XIII. 
The half of this volume is occupied by a subject, we may say, of interest to 
every individual in the world; Cholera Morbus. Important however as it may 
be in itself, it has now been the subject of so many volumes, treatises, and essays, 
that each singly conveys but little information that is new, and the greatest part 
of any one is a repetition of the others. Unfortunately also it cannot be said that 
all the labours of medical men have advanced our knowledge respecting this 
formidable disease much beyond what it was in the first year of its appearance. 
It would be difficult to name a subject in Pathology which medical men have ever 
so heartily and so strenuously united to investigate, and on which such a mass of 
intellect throughout every quarter of the world has directed its concentrated energy, 
and yet after sixteen years of unwearied observation, experiment, and research, we 
are obliged to confess that the cause of Cholera is unknown, its pathology inscrut- 
able, and its treatment totally unsettled. 
These reasons might be supposed sufficient to induce us to pass over very briefly 
the articles on Cholera in the present publication: as however among all the
