In reply to a still further question, the following is a reply that explains itself:—

“October 15th, 1906

“Dear Mr. Teasdale-Buckell,—I have your letter of the 12th inst. With regard to the .500/.450, I think I said 2000 ft.; it should have been about 2100 ft. As a curious confirmation of the above, I may point out that in Kynoch’s book on the ballistics of various rifles, it gives 2150 ft. as the muzzle velocity of a .450 bore rifle with 70 grains cordite and 480 grains bullet, whereas with 70 grains powder and 420 grains bullet it gives the muzzle velocity as 2125 ft.

“The muzzle velocity of a 950 grains bullet from a 10 bore Paradox, nitro powder, is 1500 ft. The bullet is made either of solid hardened lead or steel cored; see the enclosed illustrations of the latter. With regard to the rook and rabbit rifles, the .220 shoots 3 grains powder and 30 grains bullet, and the .250 7 grains powder and 56 grains bullet. Solid bullets for rooks, and hollow-point bullets for rabbits.—Yours faithfully,
