An account is given of the discovery and excavation of this small cave in the 1960s. It is recorded that archaeological finds were made, but of these, only a single human mandible can now be traced. Radiocarbon dating shows the specimen to be early Neolithic in age; a metrical analysis was less conclusive.

A statistical regression model for rapid prediction of moisture content based on measurements of dielectric capacitance and test weight was developed for Eastern Canadian corn (Zea mays L.). For 336 samples of the 1986 crop, dielectric readings were determined with a Model 919 grain moisture meter, test weight values with an Ohaus half-litre measure and moisture content values by a single-stage air-oven procedure. The regression model, which incorporates linear terms for dielectric reading and test weight plus an interaction term which is a product of the two, is an excellent predictor of corn moisture as indicated by analysis of the residuals and by the high value of the coefficient of determination (R2 = 0.95) and low value of the standard error of estimate (SEE = 0.85). Although the relationship between moisture content and dielectric reading for Ontario samples differed from that for Quebec samples, the proposed regression model helped to compensate for the difference. This model was also effective in predicting moisture content for 365 samples of 1987-crop Eastern Canadian corn. As well, it yielded a better fit to 1986-87 crop data than did the dielectric-based regression model used in CGC Corn Moisture Conversion Table No. 9.

Babb, Jeff
This paper examines the mathematical work of the French bishop, Nicole Oresme (c. 1323–1382), and his contributions towards the development of the concept of graphing functions and approaches to investigating infinite series. The historical importance and pedagogical value of his work will be considered in the context of an undergraduate course on the history of calculus.

Aveline's Hole is both one of the best-known sites with early human skeletal material in Britain and one of the most problematic in its history. First discovered and explored at the close of the 18th century, it yielded an estimated burial count of at least fifty individuals. Twentieth century work suggested a Late Upper Palaeolithic date for the material, in a context that might be called Creswellian. A recent dating programme places the human remains into the early Holocene and confirms the site as a Mesolithic cemetery in all senses of that word. Though a number of partial studies of the material have been published, no full description was attempted or published prior to the destruction of much of the collection in 1940. Recently one of us published a full study of the site history and a description and analysis of the surviving material. However, that study did note the small number of intact but undated crania that have been attributed to the site at various times. This study looks at one of these, denoted as AH9 and never previously described, in the aftermath of direct radiocarbon dating. Both direct dating and indirect analyses indicate that it is highly unlikely that this skull was part of the Mesolithic assemblage from this site.

Meiklejohn, Christopher; Babb, Jeff; Hiebert, Weldon
Over the past decade we have focused on two interrelated topics within Mesolithic burial studies, the relationship between burial number and burial date, and the chronology of Mesolithic sites with burials. Related to this has been construction of a database of metric variability and chronology for the period, an up-to-date list of known human bone finds, burial type, number of individuals, and geographic coordinates.
In previous papers we showed that, contrary to expectations, multiple burials or cemeteries (however defined) are not restricted to the Late Mesolithic but occur throughout the sequence, possibly with Upper Palaeolithic roots. Earlier analyses were primarily concerned with number of burials in a site and their absolute date. The geographic aspect, most obviously seen in latitude and longitude, was only explored in passing. We showed that patterns were largely similar for Europe as a whole and for the more circumscribed area of North-western Europe. This paper updates earlier work and uses geostatistical approaches together with other statistical procedures to provide an initial exploration of whether other patterns are hidden within the data. This may assist in answering questions such as whether the overall pattern of burial during the Mesolithic is random or patterned.
