climates, the whole of the inside of the vessel may be advantageously washed with 
the solution, well-stirred, and put on with a brush ; and it may be found a preserva- 
tive from the dry-rot, if the cause lie in the effect of confined air in the timber. A 
vessel may be freed from rats, by adding to the clear solution two or three ounces 
of oil of vitriol, or a pint of common vinegar ; the solution being placed in a dish, 
at the bottom of the hold, and the hatches well stopped, to prevent the escape of 
the gas which will be thrown off. 
In the East and West Indies, the Mediterranean, America, and on the Coast of 
Africa, the properties of the purifying and dis-infecting preparation will be fully 
estimated. To the European inhabitants of those countries, equal benefit may be 
derived from similar use of it in their habitations ; and it remains to be proved by 
experience, whether it may not obviate many causes of death in those climates. 
All orders will be punctually attended to, if addressed to, Frederic Fincham, 
Manufact u ri ng Ch emist. 
Or to the Agents for the party at Lloydfielil, Manchester, London, Liverpool, 
and Bristol. 
For the convenience of shipping, the preparation is put up in casks of 501bs. 
weight, at 3d. per lb. in a dry state, as it occupies less room than its solution, and 
salt water will extract the purifying qualities as well as fresh. 
Those who prefer the solution may have it in carboys, containing about 10 
gallons, or 100 lbs. at 3d. per lb. of which about one point, or pound, may be 
added to five gallons of water. 
In the sick wards a flat dish, containing the solution or powder, should be sus- 
pended, which will in a short time destroy the effluvia. When the dysentery 
prevails, its use will be still more beneficial ; for it has been considered, that when 
fiom the numbers confined cleanliness cannot be so immediately observed, the 
effect has added to the cause. Its use will lead materially to the comfort of those 
v. lio have water-closets in their cabins, as a very small quantity added to the water 
in the pan, will destroy every particle of effluvia. 
Hie best criterion for the proper use of the solution is the effect ofthe chlorine 
»tself . as soon as the gas is perceptible to the smell, it is in excess, and the solution 
should be removed. 
Aftei the solution has been made and the clear liquor drawn off, and applied to 
ain of the foregoing purposes, the lime which remains should on no account be 
tin own away, but thinly spread on a board between decks, and as far as it goes, it 
will absoib the carbonic acid ot the respired air and correct its deleterious proper- 
lies , or it may be better, instead of suspending the solution, to put the powder 
itself thinly in the dish, and then both operations will be going on at the same time, 
the chlorine destroying some of the noxious vapours, and the lime absorbing the 
carbonic acid. 
V\ ben the surgeon of the ship has ascertained how small a quantity of the 
solution will effect the purpose of purifying the air between decks, that quantity 
i lould be stiictly adhered to ; and when, from the effect of coming into a warmer 
latitude, he finds more is required, he should then increase the quantity. It 
> be fai ther useful to remark, that when once the quantity required is known 
s ot no consequence how much it is diluted, provided the whole mixture is 
.. ^ °} ec » an( l n °t allowed to run away before it has given out its gas : indeed, 
^ 016 <l ®' Vtn quantity is diluted, the more readily will its chlorine unite with 
. rroun ding atmosphere by acting, or being acted upon by, a more extended 
betw’ CC ^ S ^ 0U H a lso recommend the chlorine diluted solution to be sprinkled 
decks, after they have been washed, as grease would diminish the effect.
