The pH of 285 milk samples was measured from early, middle and late stages of lactation. In total, 35 individual cows were used in this study. It was found that the average pH value for all individual samples analysed was 6.63 +/- 0.08. There was no significant difference (P > 0.05) in mean pH between early, middle and late lactation. The overall data and that for early lactation displayed normal distributions.

This paper explores the roles played by local collectors, often little-known or rarely remembered, in the compilation of Britain’s Earlier (Lower and early Middle) Palaeolithic record, with reference to the work of C.E. (Charles) Bean at the Lower Palaeolithic site of Broom, and the activities of George Smith and Llewellyn and Mabel Treacher in the Middle Thames Valley. Their collecting practices, publication records, and archaeological knowledge and insights are reviewed, and their impacts assessed with reference to the activities of other contemporary collectors, and the regional archaeological records of the south-west and the Middle Thames. Their archives demonstrate that while the key sites and artefact assemblages sampled by Bean, Smith and the Treachers would not otherwise have been unknown, their work left important legacies in terms of rich artefact assemblages, site archives (Bean), and the long-term monitoring of key sites and fluvial terraces.

The charging of interest for borrowing money, and the level at which it is charged, is of fundamental importance to the economy. Unfortunately, the study of the interest rates charged in the middle ages has been hampered by the diversity of terms and methods used by historians. This article seeks to establish a standardized methodology to calculate interest rates from historical sources and thereby provide a firmer foundation for comparisons between regions and periods. It should also contribute towards the current historical reassessment of medieval economic and financial development. The article is illustrated with case studies drawn from the credit arrangements of the English kings between 1272 and c.1340, and argues that changes in interest rates reflect, in part, contemporary perceptions of the creditworthiness of the English crown.

The formation of Christendom – of Europe – was associated with a standardized worldview expressing dominion over the natural world. While some sections of medieval society, specifically monasteries and the aristocratic class, appear to have developed this paradigm, there is also evidence for heterogeneity in practice and belief. Zooarchaeologists have accumulated vast quantities of data from medieval contexts which has enabled the ecological signatures of specific social groups to be identified, and how these developed from the latter centuries of the first millennium ad. It is possible from this to consider whether trends in animal exploitation can be associated with the Christian world view of dominion, and with the very idea of what it meant to be Christian. This may enable zooarchaeologists to situate the ecological trends of the Middle Ages within the context of Europeanization, and the consolidation of a Christian society.

Paleosols were exposed in sections through four abandoned pre-Hispanic agricultural terraces surrounding an infilled mire basin in the southern Peruvian Andes. The two paleosols beneath the Tocotoccasa terrace represent the original ‘natural’ solum and a later soil formed after construction of the agricultural terrace, probably during the early Middle Horizon cultural period (615–695 AD). The soil at the current surface developed subsequent to the building up and reconstruction of the terrace, possibly during the late Late Intermediate period (1200–1400 AD). Micromorphology revealed an unexpected abundance of clay coatings within the upper terrace paleosol and surface terrace soil, a phenonemon attributed to the migration and/or accumulation of neoformed clay produced from the weathering of very unstable volcanic clasts, perhaps fuelled by arid/humid climatic oscillations and/or seasonal input of irrigation waters. The paleosols at Tocotoccasa could not be correlated with any degree of confidence with those beneath the other three terraces due to differences in pedosedimentary properties and uncertainties over chronological controls. Thus, it seems likely that either the terraces were (re)constructed and utilised over different cultural periods or that there is significant variation in the extent of weathering of material used for reconstruction of the terraces. Unfortunately, it cannot be ascertained from the data available whether the terraces were abandoned for any significant period of time prior to reconstruction and, if so, whether this was a regional phenomenon related to climate, social, or economic changes.
