1. Catarrhus lymphatic us. Lymphatic catarrh. A periodic- 

 al defluxion of a thin fluid from the noftrils, for a few hours, 

 occasioned by the retrograde moti dus of their lymphatics ; which 

 may probably be fupplied with fluid by the increafed abforption 

 cf fome other lymphatic branches in their vicinity. It is dif- 

 tinguiihed from that mucous discharge, which happens in frofty 

 weather from decreafed abforptiou, becaufe it is iefs fait to the 

 tafte ; and from an increafed fecretion of mucus, becaufe it is 

 neither fo vifcid, nor is attended with heat of the part. This 

 complaint is liable to recur at diurnal periods, like an intermit- 

 tent fever, for weeks and months together, with great fneezing 

 and very copious difcharge for an hour or two. 



I have feen two of thefe cafes, both of which occurred in deli- 

 cate women, and feemed an appendage to other hyfteric f/mp- 

 toms ; whence I concluded, that the difcharge was occafioned by 

 the inverted motions of the lymphatics of the nofcrils, like the 

 pale urine in hyfteric cafes ; and that they might receive this 

 fluid from fome other branches of lymphatic veiTels opening into 

 the frontal or maxillary cavities in their vicinity. 



Could fuch a difcharge be produced by ftrong errhines, and 

 excite an abforption of the congeilion of lymph in the drcpfy of 

 the brain ? 



2. Salivaiio tymphaiica. Lymphatic falivatton. A copious 

 expuition of a pellucid infipid fluid, occafioned by the retrograde 

 motions of the lymphatics of the mouth. It is fometimes peri- 

 odical, and often attends the hyfteric difeafe, and nervous fevers 5 

 but is not accompanied with a faline tafte, or with heat of the 

 mouth, or naufea. 



3. Naufea humida. Moid naufea confi (Is in a difcharge of 

 fluid, owing to the retrograde motions of the lymphatics about 

 the fauces, without increafe of heat, or faline taile, together 

 with fome retrograde motions of t*ie fauces or pharynx along 

 with this naufea, a ficknefs generally precedes the acl: of vomit- 

 ing ; which may ccnfiit of a fimilar difcharge of mucus or chyle
