VII.-On the Measurement of the Ilahy Guz, of the Emperor Akber. By W. CRACROFT, Esq.

[In a letter to the Editor.]

In the determination of the Ilahy guz, given in your useful tables with the June number of the Journal, I observe that Colonel HODGSON has deduced a length of 33.58 inches from the average measure of the marble slabs of the pavement of the Taj at Agra, and that other lengths which he has deduced from that building, vary from 32.54, to 35.8, a difference of 3.26 inches, or nearly one-tenth of the whole measure. Government having fixed 33 inches as an arbitrary value of the Ilahy guz, it is no longer an object of importance in point of practice to seek further for its original length; it may still however be a matter of curiosity, and as that deduced from my own measures of the marble slabs of the Taj, and other parts of the building, (made at the Colonel's request in 1826,) differs from his very much, I send you the detail of my measurement, which you can publish whenever more interesting matter be not at hand. I made use of a surveyor's measuring tape, the error of which I ascertained by marking off lengths of a well executed 2-feet brass scale, by WATKINS, on the terrace of a verandah, with a fine black-lead pencil, carefully covering the pencil marks at each division by the assistance of a magnifying lens, and obtained the following, taken off with hair compasses and measured on the diagonal scale.

[blocks in formation]

All my longest measures, from 44 to 49 slabs, being within these numbers of feet, the error has been assumed at one inch in 60 feet, or 1.720 part of the whole, and is additive, the tape being too long, and giving the lengths less than they really were.

which give 1127 slabs, equal to feet 1501 00.8 in. of the tape, or adding its error, to 18036.8 inches, and the Ilahy guz, 32.012 inches.

To this length, however, it appears to me that a correction for the mortar should be applied, as it is more probable that the marble slabs were cut to half a guz, than laid down by that measure; and from various observations, I assume this quantity at 0.03 inch between each slab, or 0.06 inch. for the guz, leaving 31.952 inches for the deduced length. I am the more satisfied that this correction is necessary, from having observed in several places, larger slabs of marble laid down, with grooves cut in them to match the junctions of the small slabs, and at the end of all of which a space had been left and filled up with mortar, equivalent to the accumulated excess of length caused by the mortar between the slabs of half a guz, and proportional to their numbers. I measured some of the larger slabs, and found their lengths as follows: guz deduced from each stone

the average of the whole giving exactly 32.0 in the Ilahy guz.

Assuming then 32 inches to be a very near approximation to the real Ilahy guz, it is worthy of observation that almost every principal apartment, or part of the building, has been planned in an integral number of guz: thus each face of the inside of the principal octagon under the central dome is 24 feet 288 inches, which is exactly equal to nine guz of 32 inches, and the north-east boorj on the river terrace is 16 feet in diameter 192 inches = six guz of 32 inches. I am therefore of opinion, that the average length of the Ilahy guz was, at the time of the building of the Taj, as nearly as can be now ascertained, a minute fraction below 32 English inches.

[ocr errors]

The two first data, chosen by Mr. HALHED, viz. the measure of an average of barley-corns, or of Musoori pice, appear to me less liable than most others to error, and the mean of these is 31.93 inches. It is probable that the length 2460 barley corns, or 400 pice, divided by 10, would give a still nearer approximation.

[We think the argument deduced from the measurement of the apartments being integrals of the guz to be conclusive, for it is the native mode of laying down the ground plan of a building always to divide the paper off into squares of some unit of length:-See the plan of the Visvesvur Shiwala in PRINSEP's Illustrations of Benares, first series. In that building the unit was also one guz, but it was the maimáree guz, of about 26 inches, still commonly employed in the town. From similar measurements of other ancient buildings, Muhammedan and Hindu, might thus be obtained with tolerable accuracy the value of linear measures of different periods.-ED.]

Wednesday Evening, the 6th August, 1834.

The Reverend W. H. MILL, D. D. Vice-President, in the chair.

Monsieur FERDINAND RENAULD, proposed at the last Meeting, was elected a member of the Society.

Mr. M. LARRULETA, at his own request was allowed to withdraw from the Society.

Read a letter from H. T. PRINSEP, Esq. General Secretary to Government, returning thanks for the Meteorological Registers furnished in pursuance of the resolution of last Meeting.

Dr. J. TYTLER addressed the meeting in explanation of the delay which had occurred in the reply of the local committee of the Oriental Translation Fund to the reference of last April, regarding the publication of Mr. YATES'S Nalodaya.

But two members of the original committee now remain in India, and the funds were lost by the failure of Messrs. MACKINTOSH and Co. It was out of their power therefore, to patronize the work to the extent that would be required for its publication in India: and the committee did not feel authorized to pledge the fund at home to adopt the work as one of its own series if printed in India, although such might probably be the event.

Mr. J. PRINSEP moved, seconded by the Vice-President, that the Asiatic So ciety should subscribe for fifty copies at 12 rupees, as suggested by the author.

Baboo RAM COMUL SEN, seconded by Mr. PRINSEP, moved as an amendment that twenty-five copies would be sufficient for the purposes of distribution to those Societies entitled to receive a copy of the Society's works. The amendment was carried by a majority of 2.
