or uterus, where it is placed on the head of the fcxitus and the sides 

 appHed to the cheeks ; the lower portion, which was open, is now closed 

 by running; the end of the cord throu<,'h the second loop, by which the 

 head is tirinly secured, as in the figure (loG). 



Instead of having the first loop at the end of the cord, Bautneister 

 makes it nearly in the middle, with the second loop at the same distance 

 as in the other halter. This allows of two cords — one on each side of 

 the head— to pull at (Figs. 157, 158). 



Binz has devised a special head-apparatus (Fig. 159), to which he 

 has given the name of " Forceps-band" {Zamjctihand). This is a band 

 of flax, silk, or some other woven material, which is at its widest part 

 about four inches broad, and in length about six or seven feet. At one 

 end is a moderately large opening, while the other is divided into two 

 portions to within some distance from the loop ; these last pass through 

 a round, movable, cork-shaped piece of wood, metal, or leather. The 

 head of the foetus is passed between the divided ends of this band, 

 which are then tightened behind the jaw by running the keeper close 

 up to the chin, the undivided portion being brought over the forehead 

 towards the nose, and the divisions passed through the loop. In this

way the head is firmly held, and powerful and direct traction can be 

 made on the head, above and below, by means of the upper part with 

 the hole at the end, and the two portions beneath. It has been found 

 particularly useful in cases of hydrocephalus. 



Schaack, in 1S48, introduced another kind of head apparatus, which 

 he designated a "sliding head-stall" {U'ticre d. coulant), but which is 

 perhaps better known in France as a " forceps halter " (licol-forccps), by 

 reason of its shape and use. It is composed of two doubled cords, one 

 of which (Fig. 100, 1, I) forms the headstall, while the other (3, 3) 

 makes the nose-band. The two arc united by a metallic runner (5) 

 which allows the apparatus to be increased or diminished in si/e at 

 will. The runner, which forms the key of the apparatus, is a piece of 

 brass or pewter a little more than an inch in length, about an inch m 

 breadth, and half an inch in thickness. It is perforated by three holes, 

 two of which are parallel and pass through the wider part of the metal, 

 while the third, placed between them, runs through its narrower surface. 

 The two ends of the head-stall loop go through the parallel holes, the cord 

 composing this being nine or ten feet long and one-third of an inch thick, 

 the loop itself being intended to lie behind the ears of the fcetus. One 

 side of the loop is fixed in the runner, by rings of waxed pack-thread
