...means “regarding” or some other frame of reference. They typically displace a more direct wording, and they’re invariably graceless and inelegant—e.g.: • “McCaskey (0–8) is the biggest school population-wise , but the smallest when it comes to youth soccer turnout.” Eric Stark , “L-L Girls’ Soccer ‘97,” Lancaster New Era , 14 Apr. 1997 , at C1. (A possible revision: Although McCaskey (0–8) has the most students, it has the smallest turnout for youth soccer .) • “ Content-wise , the slacker story reveals what other less mass-minded magazines revealed...

...first kept in 1538 . The Domesday Book , lay subsidies, and the poll tax returns of 1377–81 are poor guides to total population figures. Estimates of the population of England at the time of the Domesday Book vary from 1.5 to 2.25 million. It is accepted that population rose considerably in the 12th and 13th centuries, to perhaps 5 or 6 million or more by 1300 . Historians now place the level of the medieval population much higher than previous estimates. A lively area of debate concerns the question of how far the national population began to decline...

Most wills for people who died in the Caribbean are proved in the country of death, but if the person...

...and for this reason the majority of local government expenditure was raised and expended within the parish. Total county rates, which were levied by the parish on a magistrate's precept, were a much smaller charge nationally than total parochial expenditure (£0.3 million against £2 million in 1792 , and £0.8 million against £7 million in 1832 ). Attempts were made to curb the scale of expenditure on the poor by altering the composition of the vestry. An Act of 1818 instituted a system of plural voting for ratepayers with the aim of encouraging the domination...

... Henry V , the last play of the Second Tetralogy , is comparatively easy to date thanks to an uncharacteristic topical reference. At the start of Act 5 the Chorus explicitly compares Henry V’s welcome back to London after his campaign in France to the anticipated welcome the Earl of Essex would receive should he return victoriously from his current expedition against Tyrone’s rebellion in Ireland (5.0.30–5). Essex’s planned campaign was common knowledge as early as November 1598 , but this passage, and probably the rest of the play too, is more likely to...

Despite his mask he is recognized by Tybalt, whom Capulet has to restrain from challenging him. Romeo accosts Juliet and begs a kiss, subsequently learning her identity from the Nurse before he and his friends depart. Juliet similarly learns his. 2.0 The Chorus speaks of the mutual love of Romeo and Juliet, which they will pursue despite the dangers...

...production in Switzerland increased from about 1,000 titles to almost 14,000 per year. Just over four-fifths of the books published at the end of the 20 th century appeared in one of the national languages: 59 per cent in German, 18 per cent in French, 3 per cent in Italian, and 0.6 per cent in Rhaeto-Romanic, much of the rest being published in English. Yet these account for only about 30 per cent of the books on sale in Switzerland, with roughly 70 per cent being of foreign origins. Among Swiss publishing houses established in the 20 th century are ...
