ON STEAMSHIP PERFORMANCE, 115 
Table I1.—Abstract of the log of the Pacific Steam Navigation Company’s 
Royal Mail Steamship ‘ Quinto’ from Liverpool to St. Vincent, 1864. 
No dimensions of the ship are given. 
Table III.—Royal (West-India) Mail Packet Company, Southampton to 
St. Thomas, distance 3622 miles, from July 2nd, 1862, to June 2nd, 1863. 
This Table contains the performance of five ships, the ‘ Atrato,’ the ‘Shannon,’ 
tke ‘Seine,’ the ‘Tasmanian,’ and ‘ La Plata.’ No draft of water is given, but the 
condition of the hull is stated. 
Table [V.—Royal (West-India) Mail Packet Company, St. Thomas to 
Southampton, July 30th, 1862, to June 30th 1863. 
This Table contains the same steamers as the preceding. Table III. contains 
the performance of those ships on their outward voyage, and Table IV. their per- 
formance on their homeward voyage, during twelye months’ work. No draft of 
water on leaving port, nor area of midship section has been given, although mean 
displacement has been stated. 
Table V.—Royal (West-India) Mail Packet Company. Summary made 
from the Tables of diagrams from indicator and working of the engines be- 
longing to the various ships included in the return furnished of the perfor- 
mances from St. Thomas to Southampton, between July 30, 1862, and June 
30, 1863, as given in Table IV. 
This Table contains very useful data; the quantities of two ships have been reset 
and repeated in this condensed Report, and as far as possible the lines of the 
ships have been obtained, and the draft of water and area of midship section 
corresponding to the mean displacement are inserted in the condensed Tables. 
Tables VI., VII., VIII., and IX. contain abstracts of engineer’s log of the 
‘Great Eastern.’ 
The indicated horse-power has been given in Table IX. only; and therefore that 
performance only is available for calculation. 
Table X.—Abstract of engineer’s log of the Steamship ‘ Great Eastern,’ 
eighteen voyages, 1860-1863. 
No statement has been made of indicated horse-power. 
Table XI.—Return of H.M. Steam Line-of-Battle Ship ‘ Victor Emmanuel.’ 
This Table contains twenty-seven runs, of which sixteen were made under steam. 
Quantities of the vessel have already been given in last year’s condensed Report, 
Table V. Her performance appears in this Report under different conditions of 
draft of water and displacement, and consumption of coals. 
This Table has been condensed to eleven runs under different conditions ; and, 
although not strictly according to the form laid down in last year’s Report for the 
condensation of tables, it has been thought proper to insert the whole of the items 
given in the Report of 1863, so as to form a Table by itself. The indicated horse- 
power as given in the condensed Table has been calculated from the indicator-dia- 
grams as published in the Report of 1863. This is the only one of the condensed 
Tables in which the degree of expansion of steam has been given. It is much to 
be desired that the lines of this vessel, as also those of other ships of war, should 
be obtained from the Admiralty, in order to furnish data for analysis. 
Table XII. and XIIJ.—Résultats de la navigation des Paquebots des 
Services Maritimes des Messageries Impériales, pendant l’année 1861 et 1862. 
No particulars of these ships have been given, with the exception of the draft of 
water. 
Table X1V.—Particulars of 12 steamers indicated Ly letters of reference 
(A to K). 
No area of midship section nor displacement has been returned.
