I'enstate Jessie, the famous cow with the window in her stomach, is dead, but a now cow has been operated on to take her place, reports Hoard's Dairyman. A window was made in the left side of the rumen, or first stomach, which permits the investigator to study and analyse the contents of the rumen. Important bacteriological studies wore being made with Ponstnto Jessie, Imt tliey wore interrupted by her death. In t.lio work dono with this cow it was found that 90 per cent, of tho bacteria in her rumen were of a new type. '1 lieso were named Flavohactorium vitarumon. It was found that those organisms manu fact tired vitamin B when this substance was omitted from tho cow's ration, lhen. when substitutions and additions wore made to tho feed, the bacterial picturo changed remarkably. The information so far gained may not have any particular practical value, but it is interesting to learn what goes cn insido a cow. 1 his work may lead to very important information.
