Karst-water and karst-water-maps Dr. Francis Pávai-Vajna. Hungárián text on p. 402 U. D.C. 551.497 : 551.444 (084.2) The author informs us of interesting new statements in connection with the origin of karst-waters. In eontrast to Ilis earlier views he takes to the opinion, that the karstwaters of the Central Hungárián Mountains are alsó of abyssic origin. He verifies tliis with numerous traces of thermal water spouting from greater depths (hydrothermal mineral associations, caves). According to his view, the surfacial precipitation waters cannot possibly percolate to great depths. Neue Vorstellungen in Zusammenhang mit dem Karstwasserproblem Franz Albel. (UngarÍBcher text p. 406) V. D. C. 551.487 : 551.444 In der Abhandlung des Yerfassers sehen wir das Problem der Karstwassergefahr im Gebiet unserer paleogenen Kohlenbecken, in der Nahe von Budapest, in völlig neuem Lichte. Aus seinen Beobachtungen, als auch aus den veröffentlichten Abbildungen und Tabellen geht hervor, dass in grösseren Tiefen unter Meeresspiegel (von 200—300 m angefangen) viel weniger Karstwassereinbruch zu erwarten ist. Hier fehlen namlich schon die mit Wasser gefüllte, grosse Spalten und Höhlen. Auf Grundé dessen ist zu hoffen, dass wir unsere in grosse tiefen verworfene und noch unangetastete Kohlenschatze auch abbauen werden können. The interaction between karst-coal and mine-water in Dorog Paul Takács. (Hungárián text on p. 414) U. D. C. 551.497 : 551.444 : 622.5 (439.115 Dorog) The karst-coal of Dorog is of an ion-changing quality because of its contents of huminic acid and humates and is so able to change the combination of the mine-water. Theoretically, its effect is softening too, but can alsó be a hardening one. Somé observations show, that the latter case occurs in the working of mines; however, in laboratory investigations all the examined samples had a softening effect. The bulk of the samples modified the hard earthen-alcaline-hydrocarbonate containing mine-water of karstic origin (so called triadic water) into alcaline-hydrocarbonate water of little hardnesss. Waters of similar composition occurred among mine-waters too, as records of the mining-laboratory show. The catalytic effect of mineral waters Dr. Nicolas Frank. IHungarian text on p. 416) U. D. C. 553.7 : 541.128 In the carrying out of my work I was directed by practical and theoretical viewpoints. I investigated the catalytic effect óf the valuable mineral-water of the new springs in Budapest—Margaret island. I wanted to elucidate on the one hand the regularity of the process of the catalytic effect, on the other hand the velocity of reaction. By way of calculation I succeeded to verify, that the values received from the experiments result from two reactions taking place parallel to each other. The first of them is a dissolution surplus, which separates according to the exponential, not the monomolecular type of reaction, very swiftly and in a short time, the other taking place in conformity with the monomolecular pattern reaction, of a slow and prolonged character. I found considerable catalytic effect in such kind of mineral water, in the mass of 1000 g of which the quantity oíNa, Ca, Mg and HCO

z ions was 744 mg, at the presence of 0,9 mg of ferric ions and 133 cm

3 of carbonic acid, and therefore essentially less, than was necessary in model experiments to produce catalytic effect. Illustrative representation of the chemical composition of drinking water Dr. John Páter. (Hungárián text on p. 428) U. D. C. 628.11 : 543.3 (084.2) The author worked out a completely new method for the illustrative representation of the chemical composition of drinking water. The essence of it is shown in the figures. This technique is especially useful for such practicing specialists, who have no preliminary training in chemics, as are physicians practicing in drinking water hygiene. By the form of the published figures, namely, one can survey at a glancé the chemical composition of any drinking water in question. La documentation moderne en matiere hydrologipue Par Woldemar Lászlóffy, docteur és sc. techn. (Texte hongrois p. 431) U. D. C. 551.4./8 (083.45 + 084.2/3) Le Service Hydrologique hongrois a commencé, des le débit de l'année hydrologique 1948—49, la communieation d'un Bulletin Hydrologique Mensuel ayant pour but de fournir aux milieux intéressés, dans le plus court délai possible, un renseignement général sur les observations faites aux stations les plus importantes. I. Le régime des riviéres est caractérisé dans le Bulletin ,par les hauteurs d'eau et débits moyens, minima et maxima mensuels relatifs a 18 profils choisis. Les valeurs analogues de la décade de 1931 a 1940 fournissent un terme de comparaison. Les débits spécifiques et les indices d'écoulement y figurent aussi (voir 1" tableau). Un graphique montrant la variation journaliére du niveau d'eau et du débit observée á quelques stations importantes compléte cette partié de la publication. Pendant les mois d'hiver les indications relatives aux glaces sont également marquées sur le dit graphique. II. Les données météorologiques font l'objet du bulletin mensuel de l'Institut de Météorologique. C'est pourquoi le Bulletin Hydrologique se borne a la publication des résultats d'observations de 10 stations ayant une importance hydrologique (précipitations atmosphériques, température, évaporation, insolation). L'allure de la température de l'air et de l'eau ainsi que les précipitations journaliéres sur 4 postes d'observations sont représentées en graphiques. Enfin, la publication comprend les cartes des précipitations mensuelles, exprimées en millimétres et en pourcentage des moyennes de la période de 1901 a 1930. (Figure 1.) 478-
