76 Capt. Parlbifs Rifle Rocket — New Periodical Work. 



placed at a no less distance from the target than one mile ! 

 one of which, at this amazing distance, penetrated the target ; 

 two others ranged in fine parallel lines even over the target, 

 one of these to the distance of 2300, and the other 2400 

 yards. To the professional man it were needless to offer re- 

 marks on the consequences deducible from this successful 

 experimental result in the department of projectiles. The 

 State and service at large can be no less interested on a prac- 

 tical question of this kind, extending, as it does, its import- 

 ance to the science in general ; and our regret is proportion- 

 ably awakened at knowing that the experiment, submitted so 

 long back to our late Noble Commander-in-chief as 1815, 

 and before the Congreve rocket had reached India, should not 

 earlier have been put to the test. 



It is to be hoped that some individual of office, or of the 

 ordnance branch, will publish, for their brother officers, a 

 correct table of yesterday's rocket practice, and that hereafter 

 a comparative trial may be exhibited on the same ground with 

 the Congreve and Capt. Parlby's rifle rocket. — Calcutta John 

 Bull 



The following is an accurate account of the range, &c, of 

 the rocket fired by me on the 1st of December, before Major 

 Wood, Capt. Oliver, and Capt. Nichelson, &c. 



Length of the tube through which the rocket was fired, 16 

 feet. — Elevation 18 degrees. — Range to the first graze where 

 the rocket lodged, 1473 yards 2 feet. — Penetration into the 

 ground exactly five feet. 



The size of the rocket is that which according to pyrotech- 

 nical rules is denominated al| pounder, a leaden ball of the 

 diameter of the mould being that weight ; but a rocket of this 

 size, when filled with composition and complete with its head, 

 stick, &c, weighs about 5 pounds 8 ounces. 



From the penetration of the rocket into the ground at the 

 distance of 1473 yards from the place from which it was fired, 

 it may be presumed that had the rocket been thrown at a 

 higher elevation, the range would have been extended beyond 

 a mile. The range of the larger rockets is expected to be 

 3000 yards. Samuel Parlby, Model Master.
