Transverse sections of Chirodipterus australis and Griphognathus whitei are used to demonstrate the histological structures of the rostral and symphysial tubuli in Devonian lungfish. The walls of the tubuli are composed of bony tissue indistinguishable from the cancellar bone found in dermal bone. It has many spaces and perforations, and is contiguous in places with the cancellar bone of the external dermal bone. The walls of lateral-line canals have the same histological structure as the walls of the tubuli; they also intercommunicate with them. The tubuli and the lateral-line canals open to the surface through large perforations on the external surface. In Griphognathus the walls of the tubes under the external dermal bone have two layers: the outer one is dense bone, but the inner one has the appearance of calcified fibrous connective tissue of the kind associated with the tissue surrounding the lateral-line canals in living lungfish. The tubuli are closely related to the pore-canal system via canals that penetrate the dermal bone; this same relationship has been observed in Dipnorhynchus and Speonesydrion. The intimate connection between the tubuli and the lateral-line system suggests that they were formed by the sinking of neuromasts into and under the external dermal bone, with their walls surrounded by cancellar bone. 相似文献

Roland Barthes observed that though there is a ‘lover's discourse’ shared by all those who are in love, it is a discourse ignored or disparaged by ‘surrounding languages’. Concerned that the discourse of heritage may participate in this closure against the ‘in love’ experience, I begin to explore ways the field of heritage studies might start speaking this language. Specifically, I ponder the ways that a young Chinese woman in the film Days of being wild, following the breakup of a love affair, becomes locked in a landscape of lost love that is populated with objects sticky with affect, objects which although they transmit painful affects nevertheless bind her by a dynamic that Lauren Berlant terms ‘cruel optimism’. I then turn to imagine the way a Balinese house compound gateway might, in a similar way, have become impregnated with affects relating to victims of the 1965–1966 killings in Bali and how, for those left behind, it might assume the ability to ‘presence’ a lost one. Archaeology and heritage studies have great potential to foster empathy with the experience of past others, but this calls for a sophisticated understanding of how objects become imbued with affect and how they transmit it. 相似文献

Law is central to the construction of sanctity in Adam of Eynsham’s Magna vita of Hugh of Lincoln (1186–1200). Hugh had no formal training in canon law, and, beyond the Magna vita, there is no evidence to suggest that he was a particularly proficient judge. If that lack of legal training was not a problem in Hugh’s lifetime, it had become a more sensitive issue by c.1212, the date of the composition of the Magna vita. Rather than ignoring the law, or denying its importance, Adam attempted to demonstrate that Hugh received mastery of legal argument as a divine gift, and multiple miracles involve Hugh correcting legal scholars. Recognising these careful patterns of construction raises problems for reading Adam’s Magna vita. While Adam has traditionally been characterised as a truthful biographer, this reading suggests he was engaged in a more complex project of marrying sanctity to legal learning. 相似文献
