AbstractThis paper is an elaboration of the author's contribution to the 1938 British Association discussion on the distribution and migration of British Lower Palaeozoic faunas. It concerns mainly the faunas of Western Europe and North America and presents in summary the author's conclusions regarding faunal affinities and directions of immigration of the Asterozoan element in those areas. There is a notable agreement with Stubblefield's conclusions regarding the trilobite element, especially as concerns the Ordovician. The scope of the discussion is here extended to include notes on Devonian and Carboniferous faunas and some Cystid references. The paper concludes with some systematic notes, and three new generic names are proposed.

Abstract:Research on Somali mobility and migration has predominantly focused on forced migration from Somalia and diaspora communities in Western Europe and North America, neglecting other experiences and destinations. This article traces the journeys of Somali traders from East Africa to China, mapping the growth of a transnational trading economy that has offered a stable career path to a few but a chance to scrape by for many others. Understandings of migration and mobility must encompass these precarious terrains, allowing for a richer examination of how individuals have navigated war, displacement, and political and economic change by investing in transnational livelihoods, not just via ties to the West, but through the myriad connections linking African economies to the Gulf and Asia.

The Subject

It is proposed in the following pages to give a concise account of the progress of investigation of the lower Palæozoic rocks during the last forty years. The subject may naturally be divided into three parts: 1. The history of Silurian and Upper Cambrian in Great Britain from 1831 to 1854; 2. That of the still more ancient Palæozoic rocks in Scandinavia, Bohemia, and Great Britain up to the present time, including the recognition by Barrande of the so-called primordial Palæozoic; fauna; 3. The history of the lower Palæozoic rocks of North America.

AbstractFrom the late 1950s, Africans seeking higher education went to a rapidly increasing number of destinations, both within Africa and overseas. Based on multi-sited archival research and memoirs, this article shows how Africans forged and used new routes to gain access to higher education denied to them in their territories of origin, and in this way also shaped scholarship policies across the globe. Focusing on British-ruled territories in East Africa, the article establishes the importance of African intermediaries and independent countries as hubs of mobility. The agency of students and intermediaries, as well as official responses, are examined in three interconnected cases: the clandestine ‘Nile route’ from East Africa to Egypt and eastern Europe; the ‘airlifts’ from East Africa to North America; and the ‘exodus’ of African students from the Eastern bloc to western Europe. Although all of these routes were short-lived, they transformed official scholarship provisions, and significantly shaped the postcolonial period in the countries of origin.

Peanut allergens are both stable and potent and are capable of inducing anaphylactic reactions at low concentrations. Consequently, the consumption of peanuts remains the most common cause of food-induced anaphylactic death. Since accidental exposure to peanuts is a common cause of potentially fatal anaphylaxis in peanut-allergic individuals, we tested for the presence of peanut protein in chocolate bars produced in Europe and North America that did not list peanuts as an ingredient. Ninety-two chocolate bars, of which 32 were manufactured in North America and 60 were imported from Europe, were tested by the Veratox assay. None of the 32 North American chocolate products, including 19 with precautionary labeling, contained detectable peanut protein. In contrast, 30.8% of products from western Europe without precautionary labeling contained detectable levels of peanut protein. Sixty-two percent of products from eastern Europe without precautionary labeling contained detectable peanut protein at levels of up to 245 ppm. The absence of precautionary labeling and the absence of the declaration of “peanut” as an ingredient in chocolate bars made in eastern and central Europe were not found to guarantee that these products were actually free of contaminating peanut protein. In contrast, North American manufacturers have attained a consistent level of safety and reliability for peanut-allergic consumers.

For several years I have been engaged in investigating the Dinosaurs of North America, where these extinct reptiles were very abundant during the whole of Mesozoic time. The results of my study have been published from time to time, and I have already had the honour of presenting some of these to the British Association. In carrying out this investigation so as to include the whole group of Dinosaurs, wherever found, and bringing all under one system of classification, it has been necessary for me to study the remains discovered in Europe, and I have made several visits to this country for that purpose.
