Title: The copper proteins Abstract: The presence of copper in plant and animal tissues has been known since 1816 and 1833 respectively, but until the 1920's it was usually assumed to be there by accident. Nevertheless in 1847 HARLESS had detected copper in snails and had shown that it existed in combination with the blood proteins in these invertebrates. Between 1920 and 1930 nutritional studies established that copper was an essential trace metal and was necessary for haemopoiesis. Since that time a large number of copper-containing proteins have been isolated from animal, plant and microbial sources. Some of these proteins have well defined functions such as enzyme activity or the ability to transport oxygen, while others have no known function.

Title: The hypothalamo hypophyseal system Abstract: The hypothalamo hypophyseal neurosecretory system is concerned with the production and secretion into the blood stream of the two hormones-oxytocin and vasopressin: the former is an uterine muscle contractant and lactogenic principle, the latter having important antidiuretic effects.

Title: Extrachromosomal factor determinants Abstract: In the early days of bacteriology even eminent bacteriologists like Koch, Cohn and Migula believed in the doctrine of monomorphism - the constancy of bacterial species-despite conflicting observations made by Pasteur on attenuated strains of Bacillus anthracis. Any variants that were discovered were dismissed as contaminants or as "Aberrant" or "Degenerate" or "Involutionary" forms. Nowadays they might have called them "L" forms. The concept of variation began to be taken more seriously after the discovery of lactose-fermenting strains of E. coli which appeared in the papilla on the surface of a non-lactose fermenting strain, because such variants could hardly be contaminants or aberrant. There is evidence about another type of variation brought about by small genetic carrying particles in the cytoplasm. This has been shown by their non-random appearance during the growth of culture. These genetic-carrying particles which lie extrachromosomally are known as plamids and episomes.
