meutation. In the turd'bulent suspension theory the most important factor is the mixing coeffi cient. The trend* of « t'or dii'ferent velocity distribijtioiis in shown by Fig. 8. Dobbins' basic differe-ntial-equation is given by equation (32). No solution has been found for equa'ion (32) becouse of the difficulty of eeparating the va riables. Under certain assumptions equation (32) reduce« to equation (33), respectivly to (34), Equation (34) was solved by Dobbins and introducing the removal ratio (equation 24), the result is expressed by Camp in the form of equa' ion (35). The removal in equa4io'n (35) is expressed as a function of onty three variables. The variable «„ which its not independent from and <»> was eliminated by trial-and-error solution and a convenient graphieal solution of equation (35) was presented by Prof• Camp (See Fig. 9.). In using the Fig- 9. to estimate the removal eonveniently parabolic veloci'y distribu' ion is assumed and « is computed from the equation (29), or the paraméter "H/2* according to equation (37). Finally the Dobbins-Camp theory of sedimentation is appl'ed to the subsidence of the silt-laden Sajó water. Table 1. and 11. compile the required lengths of seítling /.one t'or different depth« and rsmoval at various ohannel veloc'ties according to t-he single theory and to the turbulent retardation theory respeetively. I

L is to 'be mentioned that the se tüng lengths referring to the 100% removal in Table II. are rough estimates only. Due to the flocculat ion, especially at the sedimen ation of f'ner material (0 01 mm and sma-ller particles) the lengths of the settling zone will be considerably reduced in comparison to the lengths in Table II. Diagrammatic Coinoarison of the Contents of Medicinái Waters of the Great Hungárián Plain By I. Csin i, D. Se. (Hungiarian tex with figs. on. p. 62.) U. D. C. 551.491.43:513 3 (439.14) De ve lop ing- Maucha's star diagram, the author presen'.s gmphically he chemical contents of medicinái waters of the Great Hungárián Plain. The comparative presentation of alkatiiie waters of brinee, of bittér waters, of ear'hy, of ear hy halóid, of sodaic and iodic waters may prove useful for the implementation of the medicina! bath and water ulilizaiion projects of the 5-year Plán. Parasitological Studies IV. By I. Jaczó. D. Se. (Hungárián texl 011 p. 68.) U. D. C. 576.895:595.3+576 89512 Tho paper deals with Uvo fish parasiles little known in Hungary. The author compares phenomena ob ser ved on alburnus of Laké of Balaton and on Tisza sterlet with results ot foreign researchers, especially those of Dogjely and Javiekij.

Despre apeie minerale de pe coasta .\ordVest a masivuliii sist-cristalin Haragos (Preluca). De dr. Z. Sámsoni. (Textul ffiaghiar, íigiira p. (II) U. l>. C. 661.497:668.7 (498.4) Masivul Haragos (Preluca) se aftá íu partea de Norda Transitvaniei. In partea nord-vestieá aoestui masiv se intind catova cotine teriiore, unde se gasesc mai mutte izvoare si fántáne cu apa mineralá, a cáror cercjtare a realizat autorul in tuamna anului 1943. Uescriptia geologicá acestui toritoriu a iparút nu de mult (1., 2.). Ápelo mai sus amintita provin dintr'o partj din straturi tertiare vectii, dintr'altá parte din straturi tertiare noi; eontinutul de sare si de bioxil dc carbon provine fára indoiatá din adíinoimi mai mari. Acest continilt poatj fii privit ca iudiealie de petrot, cu atát mai mu t, caci in apropiere, in regiunea locatitátilor Kovás si Kóvárfllred sünt cuuoscute urmó serioase dé petrol. Apeie cercetate sunt urmátoarele: 1. Nord dela Kisremete, in Vatea Podului se gáseste un izvor, care nasta din formajiunile oligocene de jos, din calcar Hoion. Apa acestma contine in micá cantitate bioxid do earboa si e stáb sarat. • Din timp in tim|> din apa se inalta clabuc de gaz (CO,). 2. Apa izvorului din Valea Casului — sud de Kovás — are un miros de hilrogen su'furat, e de gust sarat §i — Iii másurá mica — de petrol; contina bioxid de carbon. Apa provine din straturi oligocene'de jos, din formatiuni Hoiane, dar este diluat en apa subteraná. 3. Vest dela Szurduk-Kápolnok, in valea Borkút este o 1,7 m aiaucá fantana, in care apa e 1,1 m inalta. Apa are un miros slab de hidrogén sulfurat, e slal) sarat §i contino bioxid de carbon, are o tamperaturá de 9,5° C. Apa provine din straturi oligocene mijlocie, csokmányiane. 4. In niediul comunei Kiskörtvélyes, lángá bisericá este o fantaná adáncá de 8 metri. Apa e sárata, cu o temperatuia de 10° C si provine din straturi tortoniane. Dintre aceste ape autorul a analizat doua, acestea sunt borvíz-sárate. Wasserversorgung von Einzelgehöften und cleren Verbesserung. Von Dr. Sz. Papp. (Ungariseher Text, Tabelle S. 23.) U. I). C.
