RETROGRADE Sect. XXIX. 7. 3, 



falivatio mg come on, repeated purges every day, for a week 



or two, arc required to eliminate the mercury from the conflii 

 tion. For this acrid metallic preparation, bei (orbed by t] 



mouths of the lacleals, continues, for a time arretted by the mef- 

 enteric gland:";, (as the variolous or ve ifons fwell t 



fubaxiilar or inguinal glands) : and, during ation of 



cathartic, is returned into the inteftines by the inverted acti< 

 of the lacleals, and thus carried out of the fyftem. 



Hence we underftand the ufe of vomits or purges, to thofe 

 who have fwallowed either contagious or poifonous materials, 

 even though exhibited a day or even two days after fuch acci- 

 dents •, namely, that by the retrograde motions of the lacteais 

 and lymphatics, the material Hill arretted in the mefenteric, or 

 other glands, may be eliminated from the body. 



3. Many inftances of milk and chyle found in ulcers are giv- 

 en by Haller, El. Phyfiol. t. vii. p. 12, 23, which admit of no 

 other explanation than by fuppofing, that the chyle, imbibed by 

 one branch of the abforbent fyftem, was carried to the ulcer, by 

 the inverted motions of another branch of the fame fyftem. 



4. Mrs. P. on the fecond day after delivery, was i'eized with 

 a violent purging, in which, though opiates mucilages, the bark, 

 and teflacea were profulely ufed, continued many days, till at 

 length (he recovered. During the time of this purging, no milk 

 could be drawn from her breaits ; but the ftoods appeared like 

 the curd of milk broken into fmall pieces. In this cafe, was not 

 the milk taken up from the follicles of the pectoral glands, and 

 thrown on the inteftines, by a retrogrefiion of the intcftinal ab- 

 forbents ? for how can we for a moment fufpect that the mucous 

 glands of the inteftines could feparate pure milk from the blood ? 

 Dr. Smellie has obferved, that loofe ftools, mi with milk, 

 which is curdled in the inteftines, frequently relieves the tuv- 

 gefcency of the breaits of thofe who itudiouily repel their miik.

5. J. F. Meckel obferved in a patient, whofe urine 'was in fmall 

 quantity and high coloured, that a copious fwe^it under the arm- 

 pits, of a perfectly urinous fmell, ftained the linen ; which ceaf- 

 i'd again when the uiual quantity of urine was difeharged by the 

 urethra. Here we mult believe from analogy, that the urine 

 was firit fecreted in the kidneys, then re-abforbed by the increaf- 

 ed action of the urinary lymphatics, and laftly carried to the ax- 

 illa: by the retrograde motions of the lymphatic branches of 

 thofe parts. As in the jaundice it is Decenary, that the bile 

 fhould firft be fecreted by the liver, and re-abforbed into the cir- 

 culation, to produce the yellownefs of the fkin ; as was form- 

 erly demonllraccd by the late Dr. Munro, (Edin. Medical Ef- 



fays)
