Tho old or builders’ Tonnage in 9th e “olumn, dednee 
The 6th colama shows tho enbic contenta of each + 
‘The Eth colamn contains the internal space and feet, which, divided by 160, gives the tonnago by Act 1864, adopted for toanago, an the assumption that light cargoes execed those of dead weight, Tt appearing 
od from the length and breadth, the depth being asmmod to be half the breadth, has tween the statistical tonnage of shipping till 1895. Cols. 1 to 4 contain the internal measnrements and register tonnage of Act 1886 and 1845, as also the Act of 1854, no other particnlars being furnished in the rogister. ; 74. , 
gth and broalth, she depth being E' recommenited by the Tonoage Commitee of 1819, asthe equitable basis for dues with the factor -27 hundredths as tho registered tonnage adopted in the bill of 1860, which, although founded on the trac external mensnratfon, was objected to on the ground of the inequality of laternol paca in ships built of timber aad those of iron. 
rom trade reports, that heavy or dead weight cargoes gr coed tho light goods eargo shipped; that numerous vessels aro nov constructed of iron as well as timber, and that tho measurements can be taken either externally or internally for both, 
Phi 1 propose to be adopted as tho equitable basis of tonnage for Nght, harbour, and other ducs, and as botween ship and ship, taking as a factor for cach clas—80, 31, or 82 hundredths of this in cubic fect, using divisor 86 for a Register Tonnage, as in 8th colown, approximating 3 per cont. less than the Old or Builders’ Tonnage, stated in column 0, ; 
ris could be elected by a modificallon of the clauses 20 to 3 of Morchant Shipping Act 1864, in accordance with te Tteport of the Toonage Committee, p. 49, February, 1860, in which ia exemplified the experimental measurement of 24 vessols, ax compared with the old rale and present Jaw, 8 of which are enumerated above, ax well as the soparato calculations of screw steauiors built of titber, of timber and jron, and of Iron, for comparison. P 
Fae Tegent internal sseagurement is advantageous to owners of light timber ship and builders of iron ships. ‘The proposed. record of measurements on paper ruled to a scale, and the use,of diagrams anil curves of arcas, affords lacilitics for forming scales of displacement, as well as the relative resistance, form, and capacity, of different vessels in columns 10 to 4 of the tabular analysis of ateawiers, ax compared with their steain power and performances at wea, coloms 20 to 65,
