Page 19 - Nothing, in fact, wants investigation so much as this powder question, and until we arrive at more definite conclusions, we cannot hope to be altogether free from accident.
Page 12 - ... three latter forms lead to the conclusion that the amount of resistance offered by the air to the motion of elongated shot is little affected by the more or less pointed apex, but depends chiefly upon the form of the head near its junction with the cylindrical body of the shot. In this neighbourhood the forms of the hemispheroidal head and the ogival head struck with a radius of two diameters are the same, and the resistances are little different.
