The connection between Godwin and Fénelon has traditionally been restricted to the famous and controversial moment in the first edition of Political Justice (1793) in which Godwin presents an example of the interdependence of rationality and ethical action. This paper argues, however, that Fénelon, and particularly his political and educational treatise Telemachus (1699), plays a significant role in a number of Godwin's subsequent fictional works. Employing Telemachus to explore the theories of education presented by Godwin in the various editions of Political Justice and The Enquirer (1797), this paper explores the manner in which Godwin's version of the Enlightenment transcendence of pedagogical power comes up against its limits. Reading this issue in relation to Godwin's argument, in ‘Of Choice in Reading’, that literature remains outside of socio-ethical corruption, three of Godwin's major novels are shown to demonstrate that Telemachus provides the chance for meta-textual moments in which the appeal to reason (the reader's rational capacity or ‘private judgement’) is at once reflected upon and produced. Reading educational theories and problems into Godwin's major fiction in this fashion helps to clarify aspects of the Godwinian (or ‘Jacobin’) novel.

A l'exception des ex-libris et annotations de Jean Flamel, le manuscrit ne contient que la fin du Psautier sur une colonne (f. 4v) : « Sire, delivre nous en l'eure de la mort. / Sire, delivre (a exponctué) nous au jour du jugement ...-.... Sire, oy m'oroison / Et mon cri a toy viengne ». « Dex a qui propre chose est d'avoir merci ...-.... que la grant misericorde de ta pitié nous absoille. Par Crist nostre Seigneur. Ainsi soit il ». « Ci fine le Psautier en françois ». « Ci doit venir aprés le livre des paraboles Salemon ».

Strontium, neodymium, and lead isotope ratios are reported for 13 Leg 115 basalts as well as 3 basalts from Texaco drill hole SM-1 on the Mascarene Plateau. The 87Sr/86Sr ratios and eNd range from 0.70330 to 0.70439 and 5.5 to 7.4, respectively, although 87Sr/86Sr ratios higher than 0.70383 are found only in SM-1 basalts. The high 87Sr/86Sr values are thought to reflect seawater Sr in secondary phases, although all samples were strongly leached in HC1 before analysis. 206Pb/204Pb ratios range from 18.53 to 18.80, and sho high 207Pb/204Pb and 208Pb/204Pb ratios relative to 206Pb/204Pb ratios, typical of Indian Ocean mid-ocean ridge (MORB) and oceanic-island basalts (OIB). Isotopic compositions of Leg 115 basalts generally fall between fields for MORB and Reunion Island basalts, consistent with the conclusion drawn from geochronological studies that Deccan flood basalt volcanism, the Chagos-Laccadive Ridge, and the Mascarene Plateau are all products of the Reunion mantle plume. Isotopic compositions of magmas produced by this plume have varied systematically with time in the direction of less "depleted," less MORB-like isotopic signatures. This compositional change has been accompanied by a decrease in eruption rate. We interpret Deccan volcanism as the voluminous beginning of the plume. Reduced entrainment of asthenosphere following melting of the plume head resulted in less MORB-like isotope ratios in magmas and a decrease in eruptive activity with time.

Twenty-four piston core sediment samples and 13 sediments and 3 basalts from DSDP Leg 78 Site 543 were analyzed for Sr, Nd and Pb isotopic compositions. The results show sediment with highly radiogenic Pb (206Pb/204Pb up to 19.8) and rather radiogenic Sr and unradiogenic Nd has been deposited in the region since the Cretaceous. The source of this sediment is probably the Archean Guiana Highland, which is drained by the Orinoco River. Pb and Sr isotopic compositions and sediment thickness decrease and 143Nd/144Nd increases northward due to a decrease in turbiditic component. This decrease is partly due to the damming action of basement ridges. Rare earth concentrations in the sediments are somewhat low, due to the abundance of detrital and biogenic components in the sediment and rapid sedimentation rates. Both positive and negative Ce anomalies occur in the surface sediments, but only positive Ce anomalies occur in the Site 543 sediments. It is unlikely that sediment subducted to the source region of Lesser Antilles arc magmas could be the cause of negative Ce anomalies in those magmas. Isotopic compositions of Site 543 basalts show some effect of contamination by seawater-basalt reaction products and sediments. Beyond this, however, they are typical of "normal" depleted MORB.

When a mantle plume interacts with a mid-ocean ridge, both are noticeably affected. The mid-ocean ridge can display anomalously shallow bathymetry, excess volcanism, thickened crust, asymmetric sea-floor spreading and a plume component in the composition of the ridge basalts (Schilling, 1973, doi:10.1038/242565a0; Verma et al., 1983, doi:10.1038/306654a0; Ito and Lin, 1995, doi:10.1130/0091-7613(1995)023<0657:OSCHIC>2.3.CO;2; Müller et al., 1998, doi:10.1038/24850). The hotspot-related volcanism can be drawn closer to the ridge, and its geochemical composition can also be affected (Ito and Lin, 1995, doi:10.1130/0091-7613(1995)023<0657:OSCHIC>2.3.CO;2; White et al., 1993, doi:10.1029/93JB02018; Kincaid et al., 1995, doi:10.1038/376758a0; Kingsley and Schilling, 1998, doi:10.1029/98JB01496 ). Here we present Sr-Nd-Pb isotopic analyses of samples from the next-to-oldest seamount in the Hawaiian hotspot track, the Detroit seamount at 51° N, which show that, 81 Myr ago, the Hawaiian hotspot produced volcanism with an isotopic signature indistinguishable from mid-ocean ridge basalt. This composition is unprecedented in the known volcanism from the Hawaiian hotspot, but is consistent with the interpretation from plate reconstructions (Mammerickx and Sharman, 1988, doi:10.1029/JB093iB04p03009) that the hotspot was located close to a mid-ocean ridge about 80 Myr ago. As the rising mantle plume encountered the hot, low-viscosity asthenosphere and hot, thin lithosphere near the spreading centre, it appears to have entrained enough of the isotopically depleted upper mantle to overwhelm the chemical characteristics of the plume itself. The Hawaiian hotspot thus joins the growing list of hotspots that have interacted with a rift early in their history.
