dcfibrincd blood, whom they consider as the founder of immunoserology. Fodors experiments in vitro however have their antecedents. At the beginning Fodor injected different microbes intravenously into rabbits and proved the decrase of the number of microbes with a breeding method, and later on the vanishing of the same from the blood of the animals. Ot this the rendered account of in the German journal: Zeitschrift für Hygiene. In this publication of his he to refers to Fodors experiments and at the same time he draws the conclusion as well according to his own experiments, as to those of Fodor, that the microbes vanish from blood in consequence of their retention in the organs, chiefly in the capillaries of the kidney. Fodor presumed the direct bactericid effect of blood and decided under the influence of the publication of Vüszokovics to prove his supposition with an in vitro experiment. Vuszokovics - to sum up - besides pointing out to the capillar retention of the microbes, had at second hand also a stimulating influence ot the development of immunoserology. Fodor came further - in consequence of same observations - to the wrong conclusion, that the bactericid capacity can be increased through raising the alcaline reaction of the blood with natrium hydrocarbonat. His experiments with natrium hydrocarbonat were repeated by the Russian bacteriologist Scsor, with a negative result. He renders account of his observations in the „Annales de l'Institut Pasteur", further on in the volume of 1891 of the „Centralblatt für Bakteriologie". The negative results of Scsor had a significant part in the fact, that Fodor finally altered his wrong suposition and ascribed the bactericid effect to certain proteins. The above mentioned examples - which are not in the least complete - also prove, that in the past a productive mutual effect and connection manifested itself between the Russian and the Hungarian medical science. This is all the more to be appreciated, as the Hungarian medical science was intently under the influence ot the German medical science in consequence of the geographical and political situation of the country.
