In chronic hypochromic anaemia the mean pepsin concentration of the gastric juice is reduced and in some patients the enzyme is totally absent (Davies, 1931; Castle, Heath, and Strauss, 1931; Meulengracht, 1932; Hartfall and Witts, 1933; Griffiths, 1934; Mullins and Flood, 1935; Aitken, Spray, and Walters, 1954). Aitken et al. (1954) divide their patients into those with and without achlorhydri...

K i n d s of gene rearrangement “ Crossing over” exists apparently in all those flowering plants which have been sufficiently investigated with regard to it. (By itself, it does not rearrange different genes, but only exchanges alleles.) Genetically i t consists in exchange of normally equal and homologous segments of a gene string (MORGAN 1911, STURTEVANT 1915, MULLER 1916). It has been proved...

(1) Rhabdoderma elegans (Newberry, 1856) (‘Coelacanthus watsoni’) from the ‘Namurian’ to ‘Westphalian C’ of the Ruhr Region (Aldinger 1931; Keller 1934; Forey 1981) and from the ‘Namurian A (E1)’ of Rosenhof near Niederhemer, northern Rhenish Mountains, Germany (Horn 1960, pl. 5, fig. 4). This taxon was also documented in the ‘Namurian’ to ‘Westphalian C’ of the British Isles, northern France, ...

Chromosome ring formation has been found in a number of difierent genera. In certain species of Oenothera and of Hypericum and in the monotypic genus Rhoeo, all the chromosomes may be united in a single ring or chain a t meiosis. Ring formation is maintained in these plants by a system of balanced lethals. In Datura, Zea, Pisum and Campanula rings of four or more chromosomes have been described...

Mirosława Narkiewicz (maiden name: Broda) was born on 19th September 1931 in Łuck (Volhynia region, today in the Ukraine).

In connection with the following case it would be of interest to know what is the lowest recorded weight of a surviving infant. A coolie woman, Tanti by caste, aged about sixteen years, came for treatment for malarial fever to the hospital on this estate on 23rd February, 1931. Her haemoglobin percentage was only 40, so she was treated for hookworm as well as malaria, and on 2nd April, 1931, he...
