Pierre Marie: Gifted Intellect,Poor Timing and Unchecked Emotionality

Pierre Marie was a prominent member of the French neurological world of the early twentieth century. Having been trained by the celebrated physician, J-M Charcot, Marie remained influenced by his teacher throughout his career. Because of this influence, his career can be logically divided into three phases: first, the early years under the direct mentorship of Charcot (1878-1893); secondly, the aftermath of Charcot’s death when Marie left his teacher’s institution, the Salpêtrière hospital and established himself at the Bicêtre hospital in southern Paris (1893-1918); and finally, Marie’s return to the Salpêtrière to assume the original Charcot chaired professorship, albeit as an aged man (1918-1925). This essay examines Marie’s career with an emphasis on documentation of the combined attributes of a gifted intellect as well as a heated emotionality. In the context of his time, these elements prompted Marie to enter into controversies and medico-political battles that advanced neurological knowledge, but likely disadvantaged him in his career successes.     

Roman evidence of a crested form of domestic fowl,as indicated by a skull showing associated cerebral hernia

In modern domestic fowls, cranial deformity associated with feather cresting is known in certain varieties. This cranial form is described in a Roman specimen from Uley in Somerset. It may indicate the differentiation of this variety by the 4th century AD.     

Fossil dogs and wolves from Palaeolithic sites in Belgium,the Ukraine and Russia: osteometry,ancient DNA and stable isotopes

Using multivariate techniques, several skulls of fossil large canids from sites in Belgium, Ukraine and Russia were examined to look for possible evidence of the presence of Palaeolithic dogs. Reference groups constituted of prehistoric dogs, and recent wolves and dogs. The fossil large canid from Goyet (Belgium), dated at c. 31,700 BP is clearly different from the recent wolves, resembling most closely the prehistoric dogs. Thus it is identified as a Palaeolithic dog, suggesting that dog domestication had already started during the Aurignacian. The Epigravettian Mezin 5490 (Ukraine) and Mezhirich (Ukraine) skulls are also identified as being Palaeolithic dogs. Selected Belgian specimens were analyzed for mtDNA and stable isotopes. All fossil samples yielded unique DNA sequences, indicating that the ancient Belgian large canids carried a substantial amount of genetic diversity. Furthermore, there is little evidence for phylogeographic structure in the Pleistocene large canids, as they do not form a homogenous genetic group. Although considerable variation occurs in the fossil canid isotope signatures between sites, the Belgian fossil large canids preyed in general on horse and large bovids.     

Palaeolithic dog skulls at the Gravettian P?edmostí site, the Czech Republic

Whether or not the wolf was domesticated during the early Upper Palaeolithic remains a controversial issue. We carried out detailed analyses of the skull material from the Gravettian P?edmostí site, Czech Republic, to investigate the issue. Three complete skulls from P?edmostí were identified as Palaeolithic dogs, characterized by short skull lengths, short snouts, and wide palates and braincases relative to wolves. One complete skull could be assigned to the group of Pleistocene wolves. Three other skulls could not be assigned to a reference group; these might be remains from hybrids or captive wolves. Modifications by humans of the skull and canine remains from the large canids of P?edmostí indicate a specific relationship between humans and large canids.     

The craniology and relationships of four species of Bos,: 4. The Relationship between Bos primigenius Boj. and B. taurus L. and its implications for the Phylogeny of the Domestic Breeds

The three previous papers in this series Grigson, 1974, Grigson, 1975, Grigson, 1976 were a study of the basic craniology of the genus Bos using B. taurus as an example. This paper deals with B. primigenius from Holocene deposits in northern Europe, studying the relationship of absolute size, cranial proportions, angles and non-measurable characters to age and sex. It concludes that the two size forms of B. primigenius are merely the expression of sexual dimorphism, that the two forms B. primigenius and B. taurus are so similar that they form a continuum and should be considered to be of the same taxon, and that where B. taurus does differ from B. primigenius the differences can usually be ascribed to breed and can be described as specializations.
