    Notes: [Auszug] We have recently explored the potentialities inherent in the determination of this relationship by photoelectric methods. The method eonsists essentially in measuring the photo-current produced on illumination of a freshly formed metallic mirror with ultra-violet light of suitable wave-lengths ...

    Notes: [Auszug] In extension of our earlier work2 on the effect of various nucleophilic reagents on the simultaneous substitution (II) and carbonyl elimination (III) reactions of organic esters of nitric acid, we have now obtained definite evidence of the great importance of such ion replacement reactions. We ...

    Notes: [Auszug] A wide variety of different objects in cells are sometimes blackened by the classical 'Golgi-tech-niques' (for example, the nuclear membrane, the cell membrane, mitochondria and granules of various kinds). It was in the nerve-cells of vertebrates that Golgi1 described his apparatus. It is still ...

    Notes: [Auszug] THERE are certain objects in cells, such as the nucleus, which obviously correspond from cell to cell and for which special names are necessary. The name 'Golgi apparatus' is commonly used with the implication that it refers to homologous bodies that exist in all or nearly all cells of animals. I ...

    Notes: [Auszug] ONE of the liveliest discussions at the Congress of the Universities of the Commonwealth, held in Cambridge during July 13-17, arose at the meeting on "Higher Technological Education". The opening speakers were Prof. J. F. Baker, head of the Department of Engineering, Cambridge, Dr. K. ...

    Notes: [Auszug] In the course of an investigation on the use of various acids for the hydrolysis of casein, we have carried out preliminary experiments with liquid sulphur dioxide. It seemed possible that the reducing properties of this material might prevent destruction of tryptophane. It was also hoped that the ...

    Notes: [Auszug] To find out what lies in this part of the cell, it is necessary to make one's examination before the cell has undergone any visible changes resulting from its death. The intestinal epithelial cell of the mouse can easily be examined in what is usually called a 'supra-vital' state ; that is, the ...

    Notes: [Auszug] We now report further evidence relating to these problems. Wrinkled pea, smooth pea, normal maize, waxy maize, and tobacco leaf starches were examined in polarized light. Wrinkled pea starch contains 98 per cent amylose and 2 per cent amylopectin9; smooth pea contains amylose and amylopectin in the ...

    Notes: [Auszug] The ending in '-in' suggests strongly that the name applies to a single chemical substance or to a group of closely allied substances (for example, adrenalin, mucin, chitin). Our objection is twofold. First, it may be argued that the time has gone past when it was desirable to give to organic ...

    Notes: [Auszug] The accompanying photomicrographs are ofPelvetia canaliculate, ecad libera and Ascophyllum nodosum ecad scorpioides, and show clearly the three-sided apical cell. Similar photographs are available showing a three-sided apical cell in Fucus spiralis var. nana, Pelvetia canaliculate ecad coralloides, ...
