Amplifier {am'-ple-fi-er) [amplificare , to enlarge]. An 

 apparatus sometimes used in microscopy for increasing 

 the magnification. It consists of a diverging lens or

 thing]. The range or extent, as of vibrations and 

 undulations, the pulse, etc.

 The trumpet-mouthed or dilated extremity of a canal, 

 as of the lachrymal canal, the receptaculum chyli, 

 the Fallopian tubes, mammary ducts, semicircular 

 canals, vas deferens, etc. Chemically, the term denotes 

 a large-bellied bottle. A. of Bryant, the apparent 

 distention of an artery immediately above a ligature, 

 due to the contraction of the vessel above the ampulla 

 where it is not completely filled wi(h clot. A. Chyli, 

 the receptaculum chyli. A., Lieberkuhn's, the cecal 

 terminus of one of the lacteals in the villi of the intes- 

 tines. A.of Rectum, the portion above the perineal flex- 

 ure. A. of Vater, the site of entrance of the common 

 bile-duct and pancreatic duct into the duodenum. 



Ampullula {am-pul' -u-lah) [dim. of ampulla, a Roman 

 wine jug]. A small ampulla, as in the lymphatic or 

 lacteal vessels. 



Amputation {am-pu-ta' -shun) \amputare , to cut away]. 

 The removal of a limb or part of the body by the 



knife, ligature, or other means, or as a result of gan- 

 grene, constriction {e.g., of the cord, in the fetus), or 

 the disease, ainhum. For special amputations see 

 Operations, Table of. A., Accidental, the separation 

 of a limb by some form of accident. A., Bloodless, 

 one in which there is but slight loss of blood, on ac- 

 count of the circulation being controlled by mechanical 

 means. A., Central, one in which the scar is situated 

 at or near the center of the stump. A., Circular, 

 that performed by making a single flap, by circular 

 sweeps of a long knife, through skin and muscles, in 

 a direction vertical to the plane of the limb. A., Cir- 

 cular Skin Flap, a modification of the circular, in 

 which the skin flap is dissected up, and the muscles 

 divided at a higher level. A., Coat-sleeve, a modi- 

 fication of the circular, in which the cutaneous flap is 

 made very long, the end being closed by being gath- 

 ered together by means of a tape. A.. Congenital, 

 amputation of fetal portions due to constriction by 

 amniotic bands of lymph. A. in the Contiguity, 

 amputation at a joint. A. in the Continuity, ampu- 

 tation of a limb elsewhere than at a joint. A., Con- 

 secutive, an amputation during the period of suppura- 

 tion or later. A., Cutaneous, one in which the flaps 

 are composed exclusively of the integuments. A., 

 Diclastic, one in which the bone is broken with an 

 osteoclast, and the soft tissues divided by means of an 

 ecraseur. Its object is to avoid hemorrhage and puru- 

 lent infection. A., Double Flap, one in which two 

 flaps are formed from the soft tissues. A., Dry. See 

 A., Bloodless. A., Eccentric, one in which the scar 

 is situated away from the center of the stump. A., 

 Elliptical, one that may be performed by a single 

 sweep, as in the circular method ; the wound, however, 

 having an elliptical outline, on account of the oblique 

 direction of the incision. A. of Expediency, one 

 performed for cosmetic effect. A., Flap, one in which 

 one or more flaps are made from the soft tissues, the 

 division being made obliquely. A., Flapless, one in 

 which, on account of destruction of the soft parts, 

 flaps cannot be formed, the wound healing by granu- 

 lation. A., Galvano-caustic, one in which the soft 

 parts are divided with the galvano-cautery, followed 

 by division of the bone by the saw. A., Immediate, 

 one done within twelve hours after the injury, during 

 the period of shock. A., Intermediary or Inter- 

 mediate, one performed during the period of reaction, 

 and before suppuration. A., Intrauterine. See A., 

 Congenital. A., Major, amputation of the extremi- 

 ties above the wrist or ankle joints. A., Mediate. 

 See A., Intermediary. A., Minor, amputation of the 

 extremities below the wrist or ankle joints. A., 

 Mixed, a combination of the circular and flap methods. 

 A., Multiple, amputation of two or more members 

 at the same time. A., Musculo-cutaneous, one in 

 which the flaps consist of skin and muscle. A., Mus- 

 culo-tegumentary. See A., Musculo-cutaneous. 

 A., Natural. See A., Congenital. A., Oblique. 

 See A. , Oval. A., Osteoplastic, one in which there 

 is section and apposition of portions of bone, in addi- 

 tion to the amputation. A., Oval, a modification of 

 the elliptical, in which the incision consists of two 

 reversed spirals, instead of the one oblique. A., Par- 

 tial, I. One in which but a portion of the extremity 

 is removed. 2. An incomplete congenital amputation. 

 A., Pathological, one done for tumor or other diseased 

 condition. A., Primary, one done after the period 

 of shock and before the occurrence of inflammation. 

 A., Racket, a variety of the oval amputation, in which 

 there is a single longitudinal incision continuous below 

 with a spiral incision on either side of the limb. A., 

 Secondary, one performed during the period of sup
