Example.-A merchant wishes to fortify 115 gallons of Wine, at 33 degrees, with 5 gallons British Plain Spirits, at 16 O.P.; what will be the strength of the Wine when fortified?

Set 83 on line B to 120 on line A, and under 115 on line A will be found 79.5 on line B.

120

= 79.5.

Multiply the quantity of proof Spirits in the Wine when fortified by 100, and divide by the quantity of Wine after the operation.

NOTE.-The Spirits added in the Example under Rule 2 give 116 as the rate per cent. fortified, or 1.6 per cent. over the legal allowance. The officer would, therefore, allow only 4 gallons to be added (without the Board's permission), which gives exactly a rate oi 10 per cent.

When Wines that have been fortified at different rates are subsequently vatted, it is necessary to shew in the vatting book the average rate of fortifying.

5-To find the average rate.

RULE.-Multiply each separate quantity by the rate per cent., and divide the total by the total number of gallons vatted. Example:

A merchant vats

It is the practice at some ports to calculate the rate per cent. on the quantity of Wine and Spirit after the operation; but, although the Spirit included in the Wine is allowed to be delivered at the Wine duty, it is not to be considered as Wine for the purpose of adding more Spirit than 10 per cent. in a fortifying operation without the Board's sanction being first obtained under G. O., 21, 1858.-(B. O. to Liverpool.)

Lime or Lemon Juice duly deposited in a bonded warehouse, inspected and approved by the Inspector of Inland Revenue, Somerset House, may be fortified with 15 parts of proof Spirits (also approved) to 85 parts of Juice. Spirits to be used in fortifying may be examined by competent officers at the out-ports. They are not to be under-proof, and consist of Rum, Gin, Brandy, Whisky, or Hollands; but plain or raw grain Spirits are not to be used.-G., O., 121, 1869.

The request,
Trade Inspector must be handed to the proper officer of Cus-
toms, at the warehouse where the Juice or Spirit may have been
deposited; that such officer is then to cause the goods to be
sampled as hitherto in bottles bearing labels setting forth the
full particulars necessary to identify the samples with the goods
they represent, that the samples are to be sealed with the official
seal, and be packed in a box, which is to be forwarded, also under
seals of office, addressed to the Principal Laboratory Officer, In-
land Revenue, Somerset House.

The bottles, corks, and boxes must be furnished by and at the expense of the person making the request, which must also be forwarded in a letter as above, advising the transmission of the sample.-G. O., 38, 1869.

Lime Juice fortified prior to importation, having been delivered duty free, officers are to observe that Spirits mixed with other materials, although coming under some other denomination, are, nevertheless, liable to duty as Spirits; and they are to take care that no Lime or Lemon Juice fortified with Spirits is delivered free of duty.-G. O., 29, 1868.

METHOD OF FINIDNG ON HEAD ROD THE QUANTITY OF SPIRITS
TO BE USED.

Given a certain quantity of Lime Juice-say 150 gallons; how much proof Spirit may be added at the authorised rate?

Set 85 on line A to 15 on line B, and under 150 on line A will be found 26-the quantity of proof Spirit required.
