Neolithic Pottery

In the present state of our knowledge of the Neolithic period in England, and especially as regards its pottery, any light that can be thrown upon it is welcome, and it is on that account that I have brought before the Society a report on two discoveries of Neolithic remains: at Pangbourne, Berks., and Caversham, Oxon.It is greatly to be regretted that owing to the circumstances of the discovery accurate observations could not be made. In May, 1928, workmen were engaged in levelling ground to make a tennis court, at “Farmhili,” Courtlands Hill, Pangbourne, and in doing so came upon, and, as is unhappily so often the case, disturbed and partly smashed a human skeleton, other animal bones, of which a few only survive, and a large bowl of coarse pottery, definitely of Neolithic type. It would seem that when found the bowl was imore or less complete, but Mr. G. W. Smith, of Reading, who visited the spot the day after the discovery, was only able to find about two-thirds of the vessel, in fragments, on the rubbish heaps of excavated material. These fragments, together with the other remains, were presented by the owner of the land, Lt.-Com. W. S. Macilwaine, R.N., to the Reading Museum, where the writer had the opportunity of examining them.

Tennis movements are characterized essentially by lateral displacements, thus external load on the lower extremities is created predominantly by friction generated between shoes and playing surfaces. This study analyzed the behavior of frictional forces and torques produced during an open stance forehand using various playing surfaces and different sport shoes. The frictional data were obtained from 12 advanced players returning a tennis ball fired from a ball machine and hitting a large Kistler force plate located at the base line of the tennis court. Using statistical ANOVA techniques, friction was found to be more sensitive to the choice of playing surface than to the choice of tennis shoe. “Fluid” type surfaces displayed the lowest frictional values in most cases. Additionally, comparison of the frictional data collected during the forehand with the measurements from a standardized laboratory test demonstrated that extrapolation of friction results from laboratory to real field conditions may lead to erroneous conclusions.

It is often difficult for laypeople to appreciate that good medicine does not reduce the percentage of people with illnesses in our population; it increases that percentage. There are proportionally more people in the United States with arteriosclerotic heart disease, diabetes, essential hypertension and other expensive chronic diseases than there are in Iraq, Nigeria or Colombia. Good medicine keeps sick people alive ... The vast expansion of the concept of health can be demonstrated in surgery, orthopedics, mental health, gynecology—indeed, in any field of medicine. People do not have operations on their knees or elbows merely to continue to be employable, for example; most of us do not work at jobs requiring physical strength. Many such operations are performed strictly so that the patient can continue to lead a "normal" life, to be able to play golf or ski. Are these justifiable medical expenses? If one is free of pain except on the tennis court, is one "ill"? ... We are also wrong to assume that medical technology, like CD players and personal computers, will become cheaper as the industry matures. When what is being improved is life expectancy, all the rules change; people are willing to pay substantially more money for relatively minor improvements. Medical technology will therefore continue to be expensive simply because it pays for companies to market a 5 percent improvement even though it might be 100 percent more expensive.
