Products made for a firm's home market may not stand up to the different climatic conditions they meet when exported. Even if the country in which exports will be used has a similar climate, the products may go through tougher environments on the way. International meteorology can show the probability of the worst that can happen.

In a previous article we have called attention to the danger of eating tinned and bottled vegetables which have been coloured by the addition of salts of copper and we have urged upon the public that no such preparations should be purchased without an adequate guarantee that they are free from copper compounds. Copper poisoning, however, is not the only danger to which consumers of preserved foods are liable. Judging from the reports of cases of irritant poisoning which appear with somewhat alarming frequency in the daily press, and from the information which we have been at pains to obtain, there can be no question that the occurrence of a large number of these cases is to be attributed to the ingestion of tinned foods which has been improperly prepared or kept. It is not to be supposed that the numerous cases of illness which have been ascribed to the use of tinned foods were all cases of metallic poisoning brought about by the action of the contents of the tins upon the metal and solder of the latter. The evidence available does not show that a majority of the cases could be put down to this cause alone; but it must be admitted that the evidence is in most instances of an unsatisfactory and inconclusive character. It has become a somewhat too common custom to put forward the view that so‐called “ptomaine” poisoning is the cause of the mischief; and this upon very insufficient evidence. While there is no doubt that the presence in tinned goods of some poisonous products of decomposition or organic change very frequently gives rise to dangerous illness, so little is known of the chemical nature and of the physiological effects of “ptomaines” that to obtain conclusive evidence is in all cases most difficult, and in many, if not in most, quite impossible. A study of the subject leads to the conclusion that both ptomaine poisoning and metallic poisoning—also of an obscure kind—have, either separately or in conjunction, produced the effects from time to time reported. In view of the many outbreaks of illness, and especially, of course, of the deaths which have been attributed to the eating of bad tinned foods it is of the utmost importance that some more stringent control than that which can be said to exist at present should be exercised over the preparation and sale of tinned goods. In Holland some two or three years ago, in consequence partly of the fact that, after eating tinned food, about seventy soldiers were attacked by severe illness at the Dutch manœuvres, the attention of the Government was drawn to the matter by Drs. VAN HAMEL ROOS and HARMENS, who advocated the use of enamel for coating tins. It appears that an enamel of special manufacture is now extensively used in Holland by the manfacturers of the better qualities of tinned food, and that the use of such enamelled tins is insisted upon for naval and military stores. This is a course which might with great advantage be followed in this country. While absolute safety may not be attainable, adequate steps should be taken to prevent the use of damaged, inferior or improper materials, to enforce cleanliness, and to ensure the adoption of some better system of canning.

All accountants make extensive use of information technology (IT) in their working lives, and IT skills have long been part of the Accounting and Finance undergraduate degree programme at the University of Glamorgan. This degree scheme was redesigned on a linear basis with effect from September 2002; one of the major changes being to integrate the teaching of management accounting and IT at the introductory level. The teaching of management accounting lends itself well to the use of IT. This paper describes both the rationale behind, and the design and development of, a case study which aims to integrate the use of IT with the development and application of management accounting techniques. The case study attempts to emulate a “ive” work‐based environment as closely as possible. Completion of tasks at intervals throughout the year form part of the assessment of the module. These are based on data from a variety of sources which students manipulate, using various software packages, in order to produce useful management accounting information. In this way, students learn both management accounting and IT skills, and how to apply these skills to provide management accounting information. The experiences of both students and staff in using the case study over a six‐year period are reported, together with a description of how the case study and its use have evolved in light of the experience.

The Minister of Civil Aviation, Lord Pakenham, has appointed Mr J. Roland Adams, K.C., to hold a Public Court of Inquiry into the accident which occurred at Mill Hill, London, N.W.7, on Tuesday, October 17, 1950, to the British European Airways Dakota aircraft G‐AG1W.

Flight, even under the most routine conditions, sets high standards of quality for all materials employed. Specifications for aviation fuels have never been obtainable without careful compromise between conflicting requirements, and present developments towards flight at higher altitudes and higher speeds accentuate existing problems and reveal new ones. This article attempts to review the known major problems arising with aviation fuels under these conditions of severity, and to indicate a number of practicable solutions.

This paper presents some preliminary and tentative observations selected from a more ambitious study of the social aims of an Australian independent (i.e. non‐govemment) school. While religion is claimed to underlie the whole structure of the school's aims, a survey of the attitudes of boys, parents, teachers, and old boys clearly demonstrated that learning about formal religion, at least, was regarded as one of the least important of the school's tasks. There was also some evidence that the school had not succeeded in fostering the Christian belief in charity by way of service rather than by way of money. Further, although it is often claimed that in the independent school teachers are parent surrogates and consequently responsible for boys' ethical problems, very few boys said that they would approach teachers with problems of a personal nature. Independent schools were established as a protest against the secularization of education. In such schools religion should become the workshop‐laboratory for reasoning about, and discussion of boys' problems, and should be the core of the individual's self‐realization.

The wetting balance is being used as the focal point to establish a quantitative measurement capability for solderability of electronic components of all configurations. This paper considers the factors influencing solderability measurement that arise directly from the thermal design and construction materials of the wetting balance instrument. The work is illustrated by the differences between the three commercial wetting balances currently manufactured within the European Community.
