mountain barometer. The makers in England except Trougliton and Dollond seem 
to think that it is a great advantage to put their instruments in small compass. For 
those intended to be used in India, it is just the reverse. Here we can always carry 
any thimr worth carrying, be it ever so heavy. If I were to order any of these llier- 
mometrical barometers to be made, I would require nothing except the thermome- 
ter part and scale made as simply and substantially as possible, and the scale should 
be capable of taking in 4,000 feet at once, by being made longer. It should be in a 
case by itself. Nothing more is required, except a tea kettle or sharing pot, anil the 
apparatus of thermometers, matches, bottles, Ovc. whieli are stuffed into the case 
might be dispensed with, hut there should be three or four spare tubes ready filled 
in a separate case, to be fitted into the scale in the event of accidents.

4. Application of Lithography to the Printing of Oriental Works. 
It has been announced, in one of the French papers, that a M. Semelet has pub- 
lished an edition of the Gulistan lithographed, which bears the most perfect appear- 
ance of manuscript. This is said to be the first attempt of the kind, and additional 
praise as to the difficulty of the undertaking, and beauty of the execution, &c. is given. 
It is hut justice, however, to the several parties to mention, that printing oriental 
works from stone has been practised in Calcutta for years, and not less than two edi- 
tions of the Gulistan have appeared from one of the Lithographic presses of that citv, 
• — the last, published in 1827. 
S. Fallacy of the Mechanical Arrangement described in No. 2. of this Work. 
At page 56, of No. 2, of Gleanings in Science, there is some account of a new in- 
vented beam Ac. in which article the editor remarks, that he can detect no fallacy 
in the experiment. I have to request him to observe, that the two weights marked 
* * counterbalance each other, as the machine will remain at rest in anv position in 
•which it is placed; and consequently the descent of the weight s performs no 
other work than to overcome the friction and inertia of the several parts of the con- 
trivance. N N 
6. Notice of a Storm, which occurred at Rewah, in February, 1823.

As , tlie occurrence of such storms, during the above month, is not frequent in this 
country I bare been induced to offer the following. description of it, copied from 
notes taken during the time it lasted. It appears to be a fact rather remarkable in 
Indian meteorology, that violent storms of several days’ duration, do invariably 
terminate in dense togs when they happen, which is very seldom, during the dry 
months ot the year. On no occasion that I recollect have I ever remarked a fog
