muft equally obftruct it in the lower part of it. See Sect. XXIX. 

 6. In the convulfive afthma thefe fweats do not occur ; hence 

 they may be diftinguifhed ; . and might be called the hydropic 

 afthma, and the epileptic afthma. 



9. 'Tranjlatw puns. Tranflation of matter from one part o 

 the fyftem to another can only be explained from its being ab- 

 forbed by one branch of the lymphatic fyftem, and depofited in 

 a diftant part by the retrograde motions of another branch ; as 

 mentioned Sect. XXIX. 7. i. It is curious, that thefe tranfla- 

 tions of -matter are attended generally, I believe, with cold fits ; 

 for lefs heat is produced during the retrograde action of this 

 part of the fyftem, as no fecretion in the lymphatic glands of the 

 affected branches can exift at the fame time. Do any ineffec- 

 tual retrograde motions occafion the cold fits of agues ? The 

 time when the gout of the liver ceafes, and the gout in the foot 

 commences, is attended with a cold fit, as I have obferved in two 

 inftances, which is difficult to explain, without fuppofing the 

 new veflels, or the matter produced on the inflamed liver, to be 

 abforbed, and either eliminated by fome retrograde motion, or 

 carried to the newly inflamed part ? See Glafs IV. i. 2. 15. 



10. Tranjlatio laElis. Tranflation of milk to the bowels irt 

 puerperal fevers can only be explained by the milk being abforb- 

 ed by the pectoral branch of lymphatics, and carried to the 

 bowels by the retrograde motions of the inteftinal lymphatics or 

 lacleals. See many inftances of this in Seel. XXIX. 7. 4. 



1 1. Tranjlatw urinx. Tranflation of urine. There is a curi- 

 ous cafe related in the Tranfaclions of the College of Phyficians 

 at Philadelphia, Vol. I. p. 96. of a girl, who labouring under an 

 ifchuria vomited her urine for many months ; which could not 

 be diftinguifhed from that which was at other times drawn off 

 by the catheter. After having taken much opium, (he feemsat 

 length to have formed gravel, fome of which was frequently- 

 brought up by vomiting. Dr. Senter afcribes this to the retro- 

 grade motions of the lymphatics of the ftomach, and the increaf- 

 cd ones of thofe of the bladder, and refers to thofe of Sect. 

 XXIX. of this work ; which fection was firft publifhed in 1780; 

 and to Macquer's Dictionary of Chemiftry, Art. Urine. 



The patient above defcribed fometimes had a difcharge of 

 urine by the navel, and at other times by the rectum, and fome- 

 times by urinous fweats.
