³ For the last half-millennium the latitude is so great relative to the age that it is often unwise to conclude anything more precise than ‘a date late in the Iron Age’ or ‘up to 500 years old’. Argument over whether a particular radiocarbon reading should be calibrated from the seventeenth to the eighteenth century (or vice versa) is therefore likely to be meaningless historically – although it may of course be possible to offer a more accurate date for the site or layer in question by comparison with other sites or by considering independent historical evidence. On many West African sites local smoking-pipes, imported pottery or metalware provide closer dating evidence for the seventeenth and later centuries.

⁴ Logically one should also distinguish between b.p. and b.p. (before present), but in practice archaeologists in Africa are not doing so consistently. But it was done – of necessity – by R. M. Clark for his ‘calibration curve’ (note 2).

⁵ One continues to see from time to time in African archaeological literature radiocarbon results expressed in terms of a range delimited by the stated standard error. Thus a laboratory reading of, say, a.d. 1130±80 is taken to mean a date of a.d. 1050–1210, indicating a simple but serious misunderstanding of the formula.

With respect to GrN-3767 and 3768 for Toguéré Doupwil (listed in (1979), 23), Dr Bedaux points out slight errors in presentation: they should read a.d. 1480±100 and a.d. 1405±45 respectively.

⁷⁰ For references, see note 29 above. In a personal communication, the authors point out that Jenne-jeno is really a large single mound rather than ‘a complex of occupation mounds’ as stated in (1979), 12Google Scholar – although it is not difficult to see how this confusion arose through the designation and description of the excavation units.

The McIntoshes undertook another extensive season of excavation and survey at Jenne in 1981, the results of which are awaited.

It is worth noting here seventeen thermoluminescence tests undertaken at the Oxford laboratory on terracotta figurines previously collected (not excavated) from Jenne (either the town or its vicinity). They all belong to the present millennium with a suggestive centring around the fifteenth century.

⁷¹ Cf. (1979), 12, 16, 23. Dr Bedaux has asked me to make a couple of corrections to that article. On p. 12, last line, Nokara Cave A is an error for Sanga Cave A. Similarly on p. 23, where three dates are listed under Nokara Cave A, the two early dates (GX-0231, 2888) actually belong to Sanga Cave A (14° 25′ N, 3° 20′ W), while only the later one belongs to Nokara.
