Wolffian Bottle

latin, usually, species, material and mouth

WOLFFIAN BOTTLE. A form of apparatus used for washing gases, that takes its name from the English chemist Peter Wolff. It consists usually of a glass bottle with three separate openings or months on the neck. 'Cho gas which it is desired to wash enters through a tube, which extends to the bottom of the purifying material and then bubbles up and passes out through an other tube. which enters the mouth on the oppo si le side of the bottle. The opening in the centre, which during the operation is usually kept closed, is used to introduce the liquid required for wash ing or to regulate the pressure. For manufactur ing purposes WoMinn bottles of a large size are employed, and in many operations a number of them are placed side by side.

A large, carnivorous, grayish fish (Anarrkichas lupus) of the North Atlantic. of little use as food, but noted for its voracity and ugliness. It reaches a length of four or five feet. The mouth is large, opens obliquely, and is fur nished with formidable teeth; the sides of the lower jaw have very strong front teeth, big canines, and tubercle-like molars which shut against coarse molars on the palatines. This dentition is adapted to crushing mollusks and sea-urchins. It bites savagely when caught, and fishermen therefore generally dispatch it as soon as possible by knocking it on the head. It is often very destructive to nets. It is much used in Iceland, both fresh and salted; and a kind of shagreen, used for bags and pouches, is made of its thick skin.

There are other species of the genus in the North Atlantic and Pacific oceans, one of which (dmarrhichas lepturus) is well known in Alaskan waters. Another Pacific coast species is the curi

ous 'wolf-eel' (An (writ ichf h as orellutas). These fishes compose the family Anarrhichadidx, and are closely related to the blennies.

Later the Royal -\eaelei ies of Berlin, Leipzig, oittingen, Tel and Vienna united in support of the plan for a complete thesaurus of the Latin language. A commission was appoiuto( to carry forward the collection of nuiterial and later to edit the work, and in MO the first part of the work appeared. Walfilin's publications consist of a large number of articles in various scientific journals, especially in his own ..trehie. Among his other important works are: intim:has von yrakus and Co.lius infipater ( 1872 ) : Lutein• iselo: 'and romaui.cieIomlturulion (1879) ; edi tions of Ampelins, CaTi 1 i I;albus, Polpenua, Publilins Syrtis, etc.
