<p>Raikoke, a remote volcano in the Kuril Islands, erupted on the 21<sup>st</sup> June 2019. The eruption injected significant quantities of SO<sub>2</sub> into the atmosphere along with volcanic ash. These plumes have been studied with tools developed for the Infrared Atmospheric Sounding Interferometer (IASI) by the Earth Observation Data Group (EODG) at the University of Oxford. IASI is a hyperspectral sensor onboard of three meteorological satellites (Metop A, B and C). Each instrument obtains near global coverage twice a day and has a spectral range which includes sensitivity to both SO<sub>2</sub> and ash: making them useful for studying the Raikoke plumes. A fast linear SO<sub>2</sub> retrieval was first applied to flag pixels with elevated amounts of SO<sub>2</sub>. With this tool it was possible to follow the Raikoke plume as it circulated the northern hemisphere above 30 degrees, with parts of the plume still visible around 2 months after the eruption took place. Next an iterative SO<sub>2</sub> retrieval was used to quantify the amount and height of the SO<sub>2</sub> in each pixel. In the first few days after the eruption took place, very high column amounts are recorded, in some cases exceeding 600 DU. Using this retrieval, a preliminary estimate of 1.6 Tg was obtained for the total amount of SO<sub>2 </sub>emitted (measured on the 23<sup>rd</sup> of June). Height information from this technique shows that there were probably multiple injection heights during the eruption and that SO<sub>2</sub> was emitted into both the troposphere and stratosphere. The tropospheric plume remains visible for just a few days after the eruption, while the stratospheric portion of the plume persists for several weeks.</p>

In recent years an increasing emphasis has been placed on the study of high temperature intermetallic compounds for possible aerospace applications. One group of interest is the B2 aiuminides. This group of intermetaliics has a very high melting temperature, good high temperature, and excellent specific strength. These qualities make it a candidate for applications such as turbine engines. The B2 aiuminides exist over a wide range of compositions and also have a large solubility for third element substitutional additions, which may allow alloying additions to overcome their major drawback, their brittle nature.One B2 aluminide currently being studied is cobalt aluminide. Optical microscopy of CoAl alloys produced at the University of Missouri-Rolla showed a dramatic decrease in the grain size which affects the yield strength and flow stress of long range ordered alloys, and a change in the grain shape with the addition of 0.5 % boron.

Matthew Cheung Salisbury, a Lecturer in Music at University and Worcester College, Oxford, and a member of the Faculty of Music at the University of Oxford, wrote this book for ARC Humanities Press’s Past Imperfect series (a series comparable to Oxford’s Very Short Introductions). Two of his recent, significant contributions to the field of medieval liturgical studies include The Secular Office in Late-Medieval England (Turnhout: Brepols, 2015) and, as editor and translator, Medieval Latin Liturgy in English Translation (Kalamazoo: Medieval Institute Publications, 2017). In keeping with the work of editors Thomas Heffernan and E. Ann Matter in The Liturgy of the Medieval Church, 2nd ed. (Kalamazoo: Medieval Institute Publications, 2005) and Richard W. Pfaff in The Liturgy of Medieval England: A History (Cambridge University Press, 2009), this most recent book provides a fascinating overview of the liturgy of the medieval church, specifically in England. Salisbury’s expertise is evident on every page.

This book is an account of the life and times of a loose friendship group (later christened the Oxford Group) of ten people, primarily postgraduate philosophy students, who attended the University of Oxford for a short period of time from the late 1960s. The Oxford Group, which included—most notably—Peter Singer and Richard Ryder, set about thinking about, talking about, and promoting the idea of animal rights and vegetarianism. The group therefore played a role, largely undocumented and unacknowledged, in the emergence of the animal rights movement and the discipline of animal ethics. Most notably, the group produced an edited collection of articles published as Animals, Men and Morals in 1971 that was instrumental in one of their number—Peter Singer—writing Animal Liberation in 1975, a book that has had an extraordinary influence in the intervening years. The book serves as a case study of how the emergence of important work and the development of new ideas can be explained, and, in particular, how far the intellectual development of individuals is influenced by their participation in a creative community.

This chapter reviews the book The Making of English Theology: God and the Academy at Oxford (2014). by Dan Inman. The book offers an account of a fascinating and little known episode in the history of the University of Oxford. It examines the history of Oxford’s Faculty of Theology from the early nineteenth century to the middle of the twentieth. In particular, it revisits the various attempts to tinker with theology at Oxford during this period and considers the fierce resistance of conservatives. Inman argues that Oxford’s idiosyncratic development deserves to be taken more seriously than it often has been, at least by historians of theology.

This chapter explores the ideas at the heart of Puritanism, examining Tobie Matthew’s early radicalism. Using the controversies over vestments in 1564–6 and the visit of Elizabeth I to the University of Oxford in 1566, the chapter shows that the idea of ‘edification’ became a central principle of Puritanism. This chapter explores the spiritual demands of edifying reform and shows how it drove English Puritans into conflict with the monarch and the Established Church. It demonstrates that Matthew’s Puritanism was rooted in the experience of Marian exiles, and that he drew on their Calvinism and their resistance texts to justify his potentially seditious view of godly magistracy and rebellion.

This chapter looks at Strenæ Natalitiæ, a volume of poems produced by the University of Oxford to celebrate the events of the birth of the Prince of Wales in 1688. The University of Oxford's Strenæ Natalitiæ was a volume of over a hundred poems, with an obligatory introductory poem contributed by vice-chancellor Gilbert Ironside. The contibutors to Strenæ Natalitiæ were not simply a cross-section of the university's membership and poetic talent, but also of its politics. In some respects, youthful naivety might have been a cause of some of the authors' willingness to embrace the birth of James Edward, despite the anxiety felt by some of their fellow authors. Some of the verse was simple, and naïve in tone. Other verses were marked by a more mystical and prophetic tone. Ultimately, the verses in Strenæ Natalitiæ were predictable in their expressions of congratulation and celebration, though some also contained carefully muted expressions of equivocation.
