I wish to anchor from the light-house is to ra- 
dius, so is 400 yards to the tangent of the angle

drant the two objects cover the one the other. 
If the distance from the light-house is to be 
less than the distance between the twoobjects, 
the Clarence sextant could not be used. As 
for instance, suppose that I am acquainted 
with a deposit of gunpowder being within the 
fort 1400 yards from the light-liouse, and by 
placing the bomb 200 yards from the light- 
house, a bearing of W. by N., I could throw my shells directly

and could not be measured by the Clarence sextant (see secon d figure) ■ 
If the triangle formed by the ship and two objects becomes obtuse, hy being ob- 
liged to steet down upon the light-house in a course not perpendicular to the ba , 
the utility of the Clarence sextant also vanishes. In surveying, it is never li 
he of any nse beyond the common sextant. And any table of corrections that can 
be made to adopt the sextant to an acute angled triangle or to an obtuse one mas 
he voluminous and involve expense; and I am aure that any man who knows no 
how to obtain what he wants in that way by using a common quadrant is not huo 
have charge of a bomb. 1 
5 . — Nepal Paper. 
Extract of a letter dated Edinburgh. 
“ I can only add briefly, that there is reason to think that if the Nepal pulp for 
making paper could be sent to this country at a cheap rate, in large quantities, it 
would form a valuable addition to the resources for making such papers as require 
great power of endurance. The banks feel much interest in it; and I should have 
liked to have had it in my power to have the experiment fairly tried here of making 
bank note paper of it; but unluckily the quantity of bricks or pulp sent was cot 
adapted to the size of the macerating engines at the paper works, which require a 
charge of 112 lbs. and the whole weight at my disposal was only 1 T J lbs. I have 
after much difficulty succeeded in getting an intelligent paper maker to try it, and 
he has just concluded his experiment, the result of which he has been prevented from 
bringing to me by indisposition. 1 look for him daily, and shall give you on some 
future occasion an account of his observations and opinion, with specimens of what 
he may have produced. You will find along with this a little bit ot an unfinished 
sheet*.” 
“ It appears to me, as far as I can judge at present, that it is desirable that a trial 
of 112 lb-, weight should be made, and also that a quantity of the paper, as made 
from it in India of ili lie rent presses, should he sent for examination and comparison. 
You will observe that in live state in which it is in the specimen sent, its gTeat sus- 
ceptibility of dilatation by damp is likely to make it useful as an hygrometer. I 
have given a piece to Mr. Adie for trial.” 
In a second letter it is observed : “ The engraver reports that even in the rude 
state in which the material appears in these specimens, it affords finer impressions 
than any English-made paper, and nearly as good as the fine Chinese paper which is 
employed for what are called Indian paper proofs.-^” 
Another trial was about to be made with some fresh stuff that had recently ar- 
rived. 
* We have seen this specimen. It is extremely tough, with something of the 
feel and appearance of oil skin. 
+ We have seen a specimen of a bank note printed on the Nepal paper 
sent home. No impression can be finer, the most delicate lines in the complicat- 
ed patterns, resembling the ornamental work called engine turning with which 
part of the note is covered, being tranferred to the paper with the most perfect 
truth aud distinctness. And yet this paper had not a tolerably even surface.
