sudden expulsion of air from the lungs. A spe- 

 cimen dissected which died of another complaint, 

 proved the vermes to be exactly the same as those 

 described to inhabit the trachea of other poultry : 

 three of the fasriolae were discovered in the usual 

 part. 



From the account given by Dr Wiesenthal, 

 Professor of Anatomy at Baltimore in America, 

 (noted by the Editors of these Transactions, p. 199.) 

 of a similar disease incident to the turkey of that 

 country, it is evidently produced, not by the same 

 species of vermis, but by a different one, destitute 

 of the essential specific character- — the lengthen- 

 ed arm ; neither does the animal appear to inhabit 

 the same part, or at least it is not confined to the 

 trachea, since we are told, that " a feather stript 

 " to within a little of the point, being introduced 

 " into the mouth, and twisted round, the animals 

 '* are frequently entangled and withdrawn." The 

 seat of this disease should seem to be confined to 

 the oesophagus, and therefore the worms may ap- 

 pear in the pharynx, and even in the mouth, and 

 cause an irritation in the larynx, without entering 

 the trachea \ and if so, would certainly be within 

 the reach of immediate remedy : whereas no sub- 

 stance can be applied to the trachea internally \ even 

 a single drop of oil introduced within the larynx, I 

 have found to be certain death in diseased chickens. 



It may be worth remarking in this place, that 

 a complaint similar to that in domestic poul-
