least, any pastures that may have become contaminated. It 

 would be better still to subject such pastures to cultivated crops 

 for one or two years. The pens should be thoroughly disinfected 

 or abandoned and burned. Mr. Cornell used his infected pens 

 for d ucks without evil result . The drainage from infected pastures 

 or pens must be guarded against, no geese nor ducks being 

 allowed on land through which, or on which it passes, and no 

 water receiving such drainage being employed for geese. In the 

 case of feeders or handlers of geese who buy the birds in large 

 numbers from many sources, a subsidiary quarantine should be 

 constantly maintained, by enclosing the birds in as small groups 

 as possible in separate pens, so that infection in one pen will not 

 endanger the whole flock. When infection is shown in a pen, 

 the diseased birds should be at once destroyed and burned, the 

 pen thoroughly disinfected, and the other birds returned, or better, 

 divided up into still smaller lots, so that infection showing in one 

 of these will not endanger the great number taken from the origi- 

 nal infected pen. The utmost care should be taken to maintain 

 the most perfect cleanliness in the pens of exposed and suspected 

 geese, and to sprinkle the floors and manure liberally with an 

 antiseptic, such as asolution of sulphuric acid in water (2:100), 

 or of phenic acid (3:100), or of a combination of the two. This 

 will do much to prevent the hatching of flies which act as infection- 

 bearers, and if these can be further excluded by screens the con- 

 dition will be still more satisfactory. Vermin of all kinds should 

 be excluded and whenever possible, separate feeders and attend- 

 ants should be furnished for the suspected geese, and those that 

 have not been exposed. 



NOTE ON HiEMORRHAGIC SEPTICEMIA IN CHICKENS AND 

 TURKEYS. 



Lucet describes a septicaemia of chickens and turkeys accom- 

 panied by dysenteric discharges. The microbe resembles the 

 bacillus gallinarum of Klein (see Vol. II, p. 254), even in the 

 immunity of pigeons and rabits when injected subcutem. Rab- 

 bits, however, suffer when injected intravenously. The proba- 

 bility is that this bacillus is identical with that of Klein. Yet in 

 this whole class of microbes of the colon group, variations, appar- 

 ently superinduced by environment, appear to result at times in
