Mr. Osmond Fisher, in an article in the January number of this Magazine, entitled “Convection Currents in the Earth's Interior”, speaks of my views in a way that may give a false conception of what they are on the subject of overthrusts. He appears (inadvertently, no doubt) to credit me with a disbelief in the thrust-planes occurring in the North-West Highlands. I may say at once that I am one of those who admire the way in which a band of enthusiastic geologists have worked out the structure of this most difficult tract of country, and thoroughly believe in the correctness of their conclusions. The principal object of my little paper in the November number of this Magazine (1908) was to caution geologists not to push their new-born views too far in trying to account for structural difficulties by overthrusts. It must be remembered that the Moine thrust-plane has been proved to no more than 10 miles overlap, but may, of course, be much more. Incidentally, I thought the paper likely to elicit a correspondence helping the interpretation of the phenomena of overthrusts.

A few years ago Mr. Carruthers described an aberrant coral, Cryptophyllum hibernicum, from the Lower Carboniferous of Bundoran, Donegal. Cryptophyllum occurred in the Lower Calp shales, which are considered to be about at the horizon of Vaughan's C2 to S1 beds. Another aberrant genus, Heptaphyllum, also from the north-west of Ireland—Lower Carboniferous shales, Sligo—forms the subject of this paper. Cryptophyllum is remarkable, first for the manner in which the earlier major septa appear—irregularly, and nearly simultaneously, instead of regularly, and in consecutive pairs, as is typical for Rugose Corals; and also in the development of only five septa instead of the normal six in the earliest growth stages. Heptaphyllum, as its name implies, develops seven septa in the young corallum. It resembles Cryptophyllum in having an early aseptate corallum, and in the way in which the earlier septa appear.

In this Magazine for November Mr. Mellard Reade referred to the difficulty of imagining the adequacy of any known force to accomplish such tremendous effects as to produce overthrusts like those which have been lately described as occurring in the North-West Highlands, and he consequently appears to be a little doubtful of the reality of the phenomenon. I think, however, that the conclusion of so many competent field geologists must be accepted, and that our theories of mountain-building must be made to fit the facts rather than the facts the theories.

In a recent article JRS (1973), 68 f. Nicholas Horsfall sought to demonstrate that Corythus, which Virgil makes the original home of Dardanus (Aen. iii, 167 f.), should be identified with Tarquinii, some 50 miles north-west of Rome, on the coast of Etruria, rather than with Cortona, roughly twice as far away, to the north, and inland. In doing so he expressed surprise that the Virgilian evidence should have been completely ignored by previous writers on the subject (p. 68): and, using the Aeneid as the main source on which his own argument was based, he supported his conclusion with a careful examination of several other aspects of the problem.

The dialects spoken in the Najd of Saudi Arabia have striking features which not only are unknown or unreported in other dialects but also retain some characteristics of the 'Arabiyya and of ancient dialects of the peninsula reported by the Arab grammarians. On both these counts, they are of paramount importance for synchronic, comparative and historical dialectology. Yet little is known of them and published materials remain scanty. It is the purpose of this article to describe in some detail the morphology of the verb, i.e., the stem, the subject markers and the object pronouns, and in the process, present phonological features and processes, in a dialect spoken in the North of the Najd, specifically that of Hāyil. This is an important town on the edge of the Jabal Shammar mountains just south of the Nafud, and some 350 miles to the north-west of Riyādh. Although the dialect manifests features which are typically Najdi, in the sense that investigation shows them to exist in other dialects of the Najd, it also possesses peculiarities all its own.

The north-west corner of Spain was long neglected by Roman archaeologists, who have tended to concentrate on the more spectacular remains to be found in the south and east. However, recently more attention has been directed there by workers of several nationalities, who have now produced a quite extensive literature on the gold mines, as well as on wider aspects, chiefly in connection with the activities of the legion VII Gemina. Yet there has been little attempt in all this to examine why a substantial military force was maintained in the region for so long. This paper aims to review that problem to about the end of the second century A.D. The evidence available is almost entirely epigraphic, chiefly consisting of epitaphs and religious dedications. Building inscriptions are scarce. For convenience all the epigraphic material from the north-west of Spain that is relevant to the disposition of the army is collected in the appendix, and in the main text reference will be made to the numbers given there. In addition a few historical passages are of importance, but the archaeological site evidence is very slight. The nature of the evidence is such that most attention must be devoted to the units attested in the region and their deployment, with little to be said about their actual bases. Previous work on the subject has been dominated by the late Antonio García y Bellido in several masterly papers. However it has tended to concentrate more on the history of the units themselves than on questions of topography and the reasons behind their presence.

This paper investigates intonation in the urban dialect of Liverpool, Scouse. Scouse is reported to be part of a group of dialects in the north of the UK where rising contours in declaratives are a traditional aspect of the dialect. This intonation is typologically unusual and has not been the subject of detailed previous research. Here, we present such an analysis in comparison with Manchester, a city less than 40 miles from Liverpool but with a noticeably different prosody. Our analysis confirms reports that rising contours are the most common realization for declaratives in Liverpool, specifically a low rise where final high pitch is not reached until the end of the phrase. Secondly, we consider the origin of declarative rises in Scouse with reference to the literature on new dialect formation. Our demographic analysis and review of previous work on relevant dialects suggests that declarative rises were not the majority variant when Scouse was formed but may have been adopted for facilitating communication in a diverse new community. We highlight this contribution of intonational data to research on phonological aspects of new dialect formation, which have largely considered segmental phonology or timing previously.

The Roman province of Germania Inferior is characterized geographically by the river Rhine—the border of the Empire—and the forts along it. From the north-west to the south-east, there are significant differences in landscape and type of rural habitation. Whether these differences are also noticeable in animal husbandry forms the subject of this article. Are there any differences in species proportions and slaughter ages between the western and eastern parts of the province, and between urban, military, and rural sites? What does this say about farming and food supply? After presenting an overview of the zooarchaeological data from Germania Inferior, I shall discuss in detail one civitas—the civitas Batavorum, with the best known zooarchaeological dataset within the province. What changes in species proportions and cattle size can be detected over time from this civitas? Is there evidence for inter- and intra-site variability and changes in butchery methods? This article's further aim is to demonstrate what kind of questions a synthetic overview of zooarchaeological datasets can address.

This book is based on over 40 years work in public health at a time of unprecedented change and challenge. The emphasis is on the practical aspects of working at different levels of action, very much ‘how to do it and how it was done’. As such it is a personal account. This period marked a new era in which the previous medical paradigm, dating from the mid-nineteenth century, was replaced by a broader, multidisciplinary approach, grounded in social science, the humanities, ecology, and public engagement with the politics of health once more coming into focus. The author uses case studies, storytelling, and real-life experience of establishing a new and revitalized public health system in the North West of England to bring the subject alive for a new generation of students and practitioners. Building on historic insights and timeless lessons from the Victorian and early-twentieth-century pioneers, he traces the evolution of the new thinking and its translation into action. The volume offers a rich menu of examples of responses to an array of new challenges ranging from new infections, such as HIV/AIDS and Ebola, to the lifestyle diseases of the new age, and the application of public health thinking to mental health and the problems of an ageing population. The external threats to health from the environment and as a result of man-made disasters and emergencies are extensively covered. The author brings a fresh approach to public health and the communication of public health issues. This work is accessible and stimulating, speaking to a wide range of audiences and sharing his passion for the subject.

Purpose The purpose of this study is to determine the students’ perceptions of librarians as teachers of information literacy at the North-West University in South Africa. Design/methodology/approach The study used a survey research method in which online questionnaires were used to gather data from students who would have attended information literacy classes. Findings Students found librarians to be effective teachers of information literacy, and they found the subject to be very useful. However, some of the surveyed students felt that a lot of the subject was presented in a short period, which could easily result in exhaustion and information overload. The use of local or vernacular languages was also indicated as an area requiring the librarians’ attention for the teachers to be more effective. Practical implications The results of this study support the assessment of librarians as teachers by students to assist them (librarians) to refine their teaching methods and to make the conduct of information literacy worthwhile for the students. Social implications The outcomes of this study may be used to advocate for more information literacy (IL) contact time with the students by librarians when negotiating with faculty. Further, these results may be used to showcase the value placed by students to IL. Originality/value This study is a welcome addition to the scant literature on the quality of teaching delivered by the librarians and the assessment mechanisms used to provide feedback on students’ learning of IL. This study is a first of its kind comparing the perceptions of librarians’ teaching abilities by postgraduate and undergraduate students.
