 SPECIES, 



1 . Catarrhus Lymphaticus. Lymphatic catarrh. A periodi- 

 cal defluxion of a thin fluid from the nostrils, for a few hours, 

 occasioned by the retrograde motions of their lymphatics; which 

 may probably be supplied with fluid by the increased absorption 

 of some other lymphatic branches in their vicinity. It is dis- 

 tinguished from that mucous discharge, which happens in frosty 

 weather from decreased absorption > because it is less salt to the 

 taste; and from an increased secretion of mucus, because it is 

 neither so viscid, 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 sneezing 

 and very copious discharge for an hour or two. 



I have seen two of these cases, both of which occurred in deli- 

 eate women, and seemed an appendage to other hysteric symp- 

 toms; whence I concluded, that the discharge was occasioned by 

 the inverted motions of the lymphatics of the nostrils, like the 

 pale urine in hysteric cases; and that they might receive this 

 fluid from some other branches of lymphatic vessels opening into 

 the frontal or maxillary cavities in their vicinity. 



Could such a discharge be produced by strong errhines^ and 

 excite an absorption of the congestion of lymph in the dropsy of* 

 the brain? 



2. Salivatio lymphatica. Lymphatic salivation. A copious 

 expuition of a pellucid insipid fluid, occasioned by the retrograde 

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

 odical^ and often attends the hysteric disease, and nervous fevers; 

 but is not accompanied with a saline taste^ or with heat of the 

 mouth, or nausea. 



3* Nausea humida. Moist nausea consists in a discharge of 

 fluid, owing to the retrograde motions of the lymphatics about the 

 fauces, without increase of heat, or saline taste, together with 

 some retrograde motions of the fauces or pharynx; along with 

 this nausea, a sickness generally precedes the act of vomiting; 

 "which may consist of a similar discharge of mucus or chyle into
