ANAEROBIC CULTURE APPARATUS, Buchner. This outfit consists simply of ji lartie (est 

 tiil)c. I'(ir uliicli (Mil .Vii. I.i37l)l) I'vrcx tulio will be found suitable, in which tlie alkaline 

 )).vr<)j{ali<)l is placed, a simple support of wood or cotton on which is placed a small culture 

 lube sucli as our No. 1H3.59H, and a solid rubber stopper No. 11.572 Xo. 5. For a full discussion

ANAEROBIC CULTURE APPARATUS, desinned by IT. 1\I. .Tones, of the United States Depart- 

 ment of .Vjjriculture. Consists of an .\lborcne stone base 2 cm thick and 12 cm square, with 

 an annular groove to recei%'C an inverted 100 nuu Petri dish. The base is provitled with 

 outlet tubes so that gas and pyrogallato methods may be used. The groove may be sealed 

 with parafhnc or ot her wax. The small amount of air enclosed, about 21) cc, permits rapid 

 results to be secured, whicli are readily visible. (Sec Journal of Bacteriologj', Vol. I, Xo. 3,

ANAEROBIC CULTURE JAR, Novy's, for gas and pyrogallic acid method.s, with removable 

 top )]ermitting Petri dishes to be used. The two sections can be clamped firmly together, 

 and arc furnished with a rubber gasket in addition to ground flanges, making an air tight 

 joint. Height of lower section, 101) mm; diameter, 140 mm. Complete with three metal 

 clamjis and gasket 11.00 



ANAEROBIC CULTURE APPARATUS, Smillie, especially designed by the author for the 

 stu(l.\ of strict anacroljc-- su<Oi as H. l)otulinus. The method depends upon the catalytic 

 action of i>latini/.ed asbestos upon oxygen and hydrogen when they are brought in contact. 

 The apparatus consists of a heavy walled Xo. 80.>1K Mus'^um .far, through the glass cover 

 of which have been ilrilled two holes in which are inserted rubber sto|)pcrs carrying l)ent 

 glass stop-cocks. One stop-cock has attached to its inner end a perforated glass bulb filled 

 with platinized asbestos; to the end of the other is attached a piece of rubber tubing extend- 

 ing to the bottom of the jar. The cover is held in place by the usual clamp, a rubber gas- 

 ket being used to make a gas tight joint. (For a complete description of the method, see 

 Smillic's article in The .lournal of Experimental Medicine. Vol. XXVI, No. 1, for .luly, 1017, 

 l)age .50, '"Xew Anaerobic Methods." The same outfit will be found useful for either gas, 

 vacuiim or pyrogallate methods, anil is particularly valuable because of the number of Petri 

 dishes or tubes which may be placed in it. Diameter of jar inside, 5 inches; depth inside, 12 

 inches. Complete as illustrated 11. .50
