    Description / Table of Contents: Zusammenfassung 392 Blutproben von Mundas aus christlichen und nichtchristlichen Gruppen, aus Ranchi (Bihar) wurden mit Hilfe der Filterpapiertechnik gesammelt und auf LDH-Varianten gestestet. 6 Fälle (1,53%) der Variante LDH Cal-1 wurden entedeckt. Dieser Wert wird verglichen mit dem von Hindus höherer und niederer Kasten aus West-Bengalen. Die Mundas ähneln den unteren Kasten mehr als den höheren (t=1,752; 0,05〉 P〉0,025).
    Notes: Summary LDH variants were tested for in 392 bloods samples taken from Christian and non-Christian Munda groups, of Ranchi, Bihar by the “filter paper technique”. Six cases of LDH Cal-1 variant were detected (1.53%). This result is compared with that obtained in Hindu upper caste and Hindu lower caste of West Bengal, and the Munda population was found to be closer to the lower caste people than the upper caste (t=1.752, 0.05〉 P〉0.025).

    Description / Table of Contents: Zusammenfassung Das Quader ist eines der Modelle, das häufig als Annäherung vieler geologischer Körper und bei der Berechnung topographischer und isostatischer Effekte angewandt wird. Die analytische Formel für die Schweresanziehung eines aufrechten Quaders enthält 24 lange Formeln, diezwar für elektronische Rechenautomat aber nicht für Berechnungen von Hand geeignet sind. Es bestand deshalb ein Bedarf für ein einfaches graphisches Mittel, welch eine rasche Abschätzung des Schwereseffektes eines Block-models ermöglichen kann, insbesondere für kleinere Aufgaben mit nur wenigen Berechnungspunkten. Dem Verfasser sind noch keine solche Diagramme bis jetzt bekannt. Die Nomogramme dieser Abhandlung sollten diesen Bedarf erfüllen; an Hand dieses Hilfsmittels sollte es möglich sein in wenigen Minuten die Schweresanziehung für jeden Punkt ausserhalb oder auf der Oberfläche eines begrenzten Quaders zu berechnen.
    Notes: Summary A rectangular prism is one of the versatile models which is often used to approximate many geological features and also for calculation of topographic and isostatic effects. The analytical formula for the gravity attraction of a right rectangular prism contains 24 lengthy expressions which though compatible for use on an electronic computer, are rather prohibitive for hand computations. Some need has, therefore, been felt for designing a simple graphical device to enable a fairly quick estimate of the gravity effect of a rectangular block model, especially for small-scale jobs involving only a few computation points. In so far as is known to the author, no such graphical device has been made available to the geophysicists. The set of nomograms presented in this communication should fulfill this long felt need. With this aid now it is possible to compute in only a few minutes the gravity attraction of a finite rectangular prism at a point lying outside or on the prism surface.

    Notes: Abstract In the present paper an arbitrary classification of the transverse cephalic curvature index has been proposed as low (up to 36.9), medium (37.0–39.9) and high (40.0 and upwards) on the basis of the study of 163 Punjabi families. The inheritance study of this index has been attempted by estimating the coefficient of correlation of the different familial combinations of 49 Punjabi families (all adults). The correlation coefficients observed for the different combinations suggest the hereditary nature of this index, but presently it could not be decided whether or not there exists any sex-influence or sex-limitation of the character, though population studies suggest significant sex difference.

    Notes: Abstract An attempt has been made to study the inheritance of the size or the Inrgeness of the head as suggested by the value of the Cephalic module or Head module. The material for the present study consists of 50 families with 76 adult offspring and 12 pairs of twins (4 MZ and 8 DZ pairs). The largeness of the head is dependent to a large extent on the individual parts of the cranium and it may be fairly assumed that the individual parts of the cranium are determined by hereditary factors, may be polygenic in nature, which are controlling their growth and development, though environment also plays its role. Presently it is not possible to ascertain the exact mode of inheritance of the head size, nevertheless, it may be stated that the size or the largeness of the head as represented by the Cephalic module is determined by polygenes in all probability with additive effects, which are too small to be traced.

    Notes: Abstract A new digenetic trematode, collected 1969–1970 at Ratnagiri (India) from the marine eel Leptocephalus conger, is described as Indostomachicola kinnei n. g., n. sp. The new genus differs from Stomachicola Yamaguti, 1934 and Allostomachicola Yamaguti, 1958 in many characteristics. The new species is characterized by an unlobed ovary, absence of receptaculum seminis, and presence of post-acetabular seminal vesicle and a ventral pit.

    Notes: Abstract A new trematode, collected in 1971 from Ratnagiri, India, is described as Follicovitellosum indicum sp. nov. A new subfamily, Follicovitellotrematinae is created within the family Zoogonidae Odhner, 1911, to receive the new genus Follicovitellosum, with its genotype F. indicum. The new species is characterized by the follicularized nature of its ovary; the ovarian follicles are posttesticular. The vitellarium is further divided into several follicles which are largely in the pre-ovarian zone, but post-acetabular and posttesticular in location.

    Description / Table of Contents: Zusammenfassung Die Entfärbung belüfteter Indigokarmin-Lösung wurde unter Hochenergie-Ultraschall studiert. Die Zugabe von leicht verdampfbaren Substanzen, wie Methanol, Äthanol und Azeton hatte beschleunigenden Effekt, während Thioharnstoff eine inhibierende Wirkung zeigt. Inhibierung wurde auch beobachtet, wenn die Indigokarmin-Lösung mit Stickstoff gesättigt war. Die Absorptionsspektra der unbeschallten und der beschallten Farblösung zeigten das Verblassen der Farben mit der Beschallungszeit. Der Bleichprozeß ist als irreversibel entsprechend der vollständigen Zerstörung der Indigokarmin-Moleküle durch HO2- und OH-Radikale, gebildet in den belüfteten wäßrigen Farbstofflösungen. Wasserperoxid beschleunigt die Entfärbung kaum.
    Notes: Summary Decolourization of aerated indigocarmine solution has been studied by high energy ultrasound. Addition of volatile substances like methanol, ethanol and acetone had accelerating effect whereas thiourea showed inhibiting effect. Inhibition was also observed when the indigocarmine solution was saturated with nitrogen gas. Absorption spectra of the unexposed and exposed dye solutions in visible region indicate the fading of colour with the time of exposure. Bleaching process was found to be irreversible due to the complete rupture of indigocarmine molecules by HO2 and OH species formed in aerated aqueous dye solution. Hydrogen peroxide was found to help very slightly the decolourization.
