SPECIES. 



1 . Catarrhus lymphaticus. Lymphatic catarrh. A periodic- 

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

 occafioned by the retrograde motions of their lymphatics ; which 

 may probably be fupplied with fluid by the increafed abforption 

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

 tinguifhed from that mucous difcharge, which happens in frofty 

 weather from decreafed abforption, becaufe it is lefs fait to the 

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

 neither fo vifcid, nor is attended v/kh 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 fymp- 

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

 the inverted motions of the lymphatics of the noilrils, like the 

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

 fluid from fome other branches of lymphatic veflels 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 congeftion of lymph in the dropfy of 

 the brain ? 



2. Sa/ivatio lymphatica. Lymphatic falivation. 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 ; 

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

 mouth, or naufea. 



3. Naufea humida. Moid naufea confifts in a difcharge of 

 fluid, owing to the retrograde motions of the lymphatics about 

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

 with fome retrograde motions of the fauces or pharynx along 

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

 ing ; which may confift of a fnnilar difcharge of mucus or chyte
