use, h*ving a conical mouth-piece of ivory, horn, or metal, 

 at one extremity, and a small tube of like material, to be 

 applied to the ear. A trumpet of this kind may be used 

 advantageously, not only for remedying the defects of hear- 

 ing, but for assisting the observer to collect feeble and dis- 

 tant sounds. Price, Figs. 775, 776, 778, 779, $1.25.

Breast Pump and Cupping Pump. An apparatus for 

 effectually drawing the breast is represented in Fig. 781 ; it 

 consists of a globular glass with an open bottom made of 

 the form of the breast, having a small neck with a brass 

 cap and valve opening outwards, to which is attached by a 

 screw, a small air pump, by which the air is rarified, and 

 the milk in consequence flows out. To use, hold the instru- 

 ment upon the breast with one hand, observing that the end 

 of the small pipe is turned upwards, and the small hole in 

 the brass cap covered with the thumb ; then work the handle 

 until the milk begins to flow, and continue occasionally to 

 pump until the glass is sufficiently full, when by removing 

 the thumb from the hole the glass will come off.

For Cupping the same pump is used, with a glass or 

 glasses of a form represented in the cut (Fig. 782). For 

 dry cupping, where it is required to produce a greater flow 

 of blood to a particular part, than is usual, the manner of 

 using is the same as the breast pump ; the glass being placed 

 upon the part to be affected and the handle worked ; the 

 blood is thus urged into the small arteries and veins, so as 

 to produce a considerable redness under the cupping glass, 

 at which place the skin is also much elevated and rather 

 inflamed. When blood is to be drawn the glass is first used 

 and the scarificator applied immediately after its removal ; 

 the glass being fixed again on the same spot and left there
