ANATOMY AND PHYSIOLOGY OF 



nal glands, which are lodged upon the 

 superior and anterior part of the thigh. 



" The deep-seated lymphatics take their 

 rise from the foot, ascend along with the 

 plantar veins, continue upward among the 

 muscles, in company with the deep-seated 

 veins, corresponding in their principal di- 

 visions to those vessels, and proceed to the 

 inguinal glands. 



"All the lymphatics of the posterior 

 limbs assemble at these glands, and here 

 form a plexus, from which several large 

 branches depart and traverse the iliac 

 glands, clinging to the sides of the iliac 

 vessels, and discharge their contents into 

 the pelvic branch, contributing to the recep- 

 taculum chyli. 



" 2. Lymphatics of the Pelvis. — The 

 vessels coming from this cavity run in 

 part to the inguinal glands, and in part 

 to the internal pelvic glands. The su- 

 perficial lymphatics about the pubes and 

 the outlet of the pelvis run and join those 

 of the extremities ; those of the perineum 

 and anus enter the cavity, and are accom- 

 panied by those coming from the croup and 

 tail, both proceeding to the glands within 

 the interior of the pelvis. AU the deep- 

 seated lymphatics accompany the veins, 

 make for the pelvic glands, form union with 

 the others, and run and empty themselves 

 into the main pelvic branch, wherein their 

 lymph mixes with that coming from the in- 

 guinal glands. 



" The lymphatics of the urinary and 

 genital organs, included in the pelvic cavity, 

 also traverse the glands lodged therein, and 

 unite with those of the parietes of the pel- 

 vis. Those of the scrotum enter the in- 

 guinal glands, as also do those belonging 

 to the sheath and penis. The ramifications 

 derived from the testicle and spermatic 

 cord take the course of the veins, and pene- 

 trate one or two of the lumbar glands 

 lodged at the entrance of the pelvis. The 

 lymphatics of the mammae, which are also 

 divisible into superficial and deep-seated, 

 run to the inguinal glands, and anastomose 

 with the superficial set belonging to the in- 

 ferior parietes of the abdomen ; but, before 



they reach these last glands, they pervade 

 those of the mamma?. 



" 3. Lymphatics of the Parietes of the Ab- 

 domen. — These vessels, in general but little 

 developed, for the most part run to the in- 

 guinal glands. The superficial set of the 

 lower parietes accompany the cutaneous 

 inguinal vein, anastomose with the lympha- 

 tics of the scrotum and mammae, and tra- 

 verse the glands in the groin : some of them 

 direct their course forward, along with the 

 cutaneous external thoracic veins of the 

 thorax, unite with the superficial lymphatics 

 of that part, and proceed to the axillary 

 glands. The deep-seated vessels of the 

 belly run in company with the epigastric 

 vein, and go to the inguinal glands, or else 

 they accompany the pectoral vein, and per- 

 vade the glands in front of the thorax. 



" The superficial or subcutaneous lym- 

 phatics of the loins join either those of the 

 croup or those of the flanks : the deep- 

 seated, which spring from the peritoneum, 

 muscles, or spinal canal, perforate one of 

 the lumbar glands, and pass onward to ter- 

 minate in the main pelvic branch. 



" 4. Absorbents of the Mesentery. — The 

 mesenteric branches, ordinarily two or 

 three in number, the most considerable 

 of which is constantly united to the great 

 mesenteric artery, receive aU the vessels 

 continued from the mesenteric glands, as 

 well as those coming from the mesentery 

 and intestines. 



" The mesenteric absorbents, extremely 

 numerous, are sustained between the layers 

 of the mesentery, where they form a vascu- 

 lar network ; many of them issue from the 

 exhalent surface of the mesentery and in- 

 testinal tube ; others take their rise from 

 the interior of the intestines, from which 

 they imbibe chyle. All these vessels con- 

 verge towards the lymphatic reserv'oir, 

 clinging in their passage around the mesen- 

 teric veins ; some, however, taking a solitary 

 course at a greater or less distance from any 

 blood-vessel. Having arrived at the root of 

 the mesentery, they pass through one or 

 two, sometimes three, of the mesenteric 

 glands, and afterwards join the principal
