Hering's ' Report/ 1855, xvii, p. 147, as also Gurlt's ' Mag. 

 Supp./ 1855. A worm-cough was observed in the form of a

 ^ij ^iv, and mucilage, was prescribed; a tea-spoonful daily. 

 In some young geese which were dull, and troubled with agi-

 a croaking voice, and froth on the beak, Przibijlko found red 

 coils of worms in the air-passages and their branches.

 I'esistentibus. Os acetabuliforme, subcorneum ; aperlura oris ampla 

 drcularis subdorsalis ; denies in fundo oris intra aperture mar- 

 ginem abdominalem 4 uncinati (os in altitudine infundibuli 4 uncinis 

 intus recurvatis munitum et in fundo cum eminentiis conicis, in 

 tabularum explicatione " punguli tegumentarii" nominatis, inuncinos 

 versis, utrique generi communibus, Dubini) ; oesophagus carnosus,

This worm, found by Dubini, in Milan, in the year 1838,
