nick cut along its centre at F, (see dotted line,) to act as a back-sight. The point of the bolt acts as a fore-sight. As the bow-string is forced to the notch by the lever of the crossbow, it is pushed under the end of the horn F. Though the bolt is now on the stock, the bow bent and the string stretched (fig. 109), the crossbow is safe and cannot be discharged without further manipulation.

Fig. 110 shows the top of the catch B. The horn F, is here omitted to avoid confusion of details. The front view of the catch B, and its swivel-pin, is given separately.
