IN the heroic Latin hexameter, after the essential alternation of long and short syllables, by far the most important feature is unquestionably the caesura. Nevertheless, ancient writers on metre dismiss it with the most cursory notice; all we get from them is that the chief caesura is the penthemimeral, the trochaic and hephthemimeral coming next; the fourth trochaic and the bucolic are usually rejected, and the trihemimeral is mentioned only by Ausonius, Modern writers, among whom are Müller and Winbolt, deal (...) with the question at greater length, but do not agree even on fundamental points, and often base their statements on an insufficient analysis of the extant remains of Latin hexameter verse. The purpose of the following paper is to attempt a more complete analysis, at least in the case of Virgil, the acknowledged master of the Latin hexameter. But before we proceed further there are two preliminaries which must be settled—what are the main types of caesura, and how many caesurae are admissible in one verse? (shrink)

The advances in treatment of HIV and the introduction of polymerase chain reaction assay for the virus now make it acceptable for HIV discordant couples where the male partner is seropositive to attempt to conceive through artificial insemination by husband (AIH) or via in vitro fertilisation. With undetectable viral load and washed sperm, there is minimal risk of transmission of HIV to the female partner, children, other patients, or staff. We describe the development of a programme of AIH for HIV (...) discordant couples and the reasoning behind offering such a programme. (shrink)
