The author first adverts to the conflicting opinions respecting the nature of this fluid, and especially to one of the latest, that entertained by MM. Gratiolet and S. Cloez, that it is an active poison.
He next describes some experiments he has made for the purpose of testing their conclusion, the results of which are in opposition to theirs, and confirmatory of certain ones of his own, showing that the fluid is a simple acrid irritant, and as such well adapted to protect an animal otherwise defenceless, and, from its sluggish habits, peculiarly exposed to danger.
