Transmission Experiments with Leucosis of Fowls
It is shown, in a carefully controlled experiment, that fowl leucemia can be readily transmitted from chicken to chicken by injection. Of 25 fowls, 13 were injected intravenously with blood from a chicken (No. 575) with erythroleucosis and 12 with blood from a chicken (No. 689) with myeloid leucosis. The injected birds and an equal number of uninjected controls were kept in tiers of alternating...
متن کاملFurther Investigation on the Transmission of Induced Tumors in Fowls
The possibility that the fowl tumor agents are of endogenous origin has been frequently suggested but no definite evidence for this idea has been produced. The demonstration of transmitting agents in induced tumors while not absolutely proof might be considered as giving support for such a conclusion. In i9u 5 Murphy and Landsteiner (9) reported the induction of two typical sarcomas in chickens...
متن کاملFurther Experiments in Typhus Fever
PRECISE INTERPRETATION OF OUR EXPERIMENTS SEEMS TO IMPOSE THE FOLLOWING CONCLUSIONS: Guinea pigs inoculated with washed Rickettsiae from Mexican typhus fever develop a disease identical with that resulting from inoculations with whole tunica scrapings, blood or other virulent material, and become thereby immunized to European typhus fever. The etiological agent of Mexican typhus fever is the Ri...
متن کاملFurther daemon detection experiments
The experiments on detection of daemons captured into geocentric orbits, which are based on the postulated fast decay of daemon-containing nuclei, have been continued. By properly varying the experimental parameters, it has become possible to reveal and formulate some relations governing the interaction of daemons with matter. Among them are, for instance, the emission of energetic Auger-type e...
متن کاملIPFP and Further Experiments
Iterative Proportional Fitting Procedure is commonly used in probability theory for construction of a joint probability distribution from a system of its marginals. A similar idea can be used in case of belief functions thanks to special operators of composition defined in this framework. In this paper, a formerly designed IPF procedure is further studied. We propose a modification of compositi...
