    as shown in Fig. 463 a, b; and consequently may serve for small dogs as well as large ones. The head-holder (shown on a larger scale in Fig. 463), is made entirely of steel and thoroughly well worked, so that no accident cau happen even with the strongest animals under opera- tion, experience having taught the necessity of having this in- strument made of the strongest material. This head-holder is movable in any direction. Two of them //, differing in size for different sized animals, go with each board. Fig. 463 passed through the mouth of the dog held The head-holder // moves round a steel bar, where it is held by the screw C. It has a central quick-working screw, which enables the operator to effect quickly any desired position of the head. The central screw moves on saddle-like bow with- out pad in a slit of the holder. The same (curved) slit contains also a cross bar B, which is the cauiue-teeth, as shown in Fig. 463 a The fastening of the animal on the operation-board is carried out as follows: In- ject the animal with 0.5 to 2 ccm. (according to the size of the animal) of a solution holding 10% of morpbium. After 15 to 30 minutes, morpliium-sleep will set in, where- upon place the animal ou the trough-shaped board, adjust one of the head-holders, draw the crossbar through the mouth behind the canine-teeth and use the central screw A; after that fasten fore- and hind-legs, and (having securely screwed down the central screw S) attach the head-holder to the “ staud.”
