    Notes: Abstract The O2 uptake through water has been measured in case of Heteropneustes fossilis during development and growth and its relationship to body size established. A higher rate of O2 uptake during the early phase of ontogenesis is related to intense growth of the respiratory surface area and increasing metabolic demand of the fish. The logarithmic plot of data for O2 uptake in relation to body size shows a statistically significant two-component curve; one related to the fish when it is a fully aquatic breather and the other when it changes to bimodal gas exchange. The onset of the air breathing habit brings about a 40% drop in O2 uptake through water, which is made good through the newly developed air breathing organ.

    Notes: Abstract Oxygen uptake in relation to body size during the early life of the fish Channa punctatus shows a significant two-component curve: one related to the fully aquatic phase and the other to the bimodal phase of respiration. The onset of the air-breathing habit around the 18–20th day after hatching brings about a 45% drop in O2 uptake through the gill/skin in water.

    Description / Table of Contents: Die Copolymerisationsparameter einiger halogensubstituierter aromatischer Amine wurden nach der Methode von Kelen-Tüdős und Fineman-Ross graphisch bestimmt. Bei der Copolymerisation mit den Comonomeren p-Toluidin oder p-Nitrophenol erwies sich die Reaktivität der halogensubstituierten aromatischen Amine in der Reihenfolge der Basenstärke ansteigend. Jedoch kehrt sich diese Reihenfolge um, wenn diese halogensubstituierten Amine mit p-Nitroanilin copolymerisiert werden. Diese Umkehr der Reaktivität wurde mit der Polarisation und Resonanzstabilisierung der Monomeren erklärt.
    Notes: Reactivity ratios of some halogen substituted aromatic amines have been determined by using Kelen-Tüdős and Fineman-Ross linear graphical methods. On copolymerization with p-toluidine or p-nitrophenol as comonomer, the reactivity of halogen substituted aromatic amines was found to be in the order of their basic strength. However, this order of reactivity gets reversed when these halogen substituted amines are copolymerized with p-nitroaniline. This reversal of reactivity has been interpreted in terms of polarization and resonance stabilization of the monomeric species.
