Despite the potential for small amounts of non-compliant kidney and liver to enter the human food chain, there was no significant increase in the risk to consumers.

The earliest weather records for Europe are found in the annals of Ireland, and tell of disastrous floods and droughts rn far back as about 2 7 0 0~. c . Such references are the only meteorological data available for years prior to the middle of the 17th century, when the barometer and thermometer were coming into use. An Irishman, Robert Boyle, did important work in developing both instruments, but the first published numerical data are pressure readings by the Bishop of Cloyne, contributed to the Royal Society in 1676.No Irish thermometer readings are known earlier than those for 1721-2 by 0. Rye, who kept a careful weather diary in his experiments on variations of human perspiration. Unfortunately his thermometer was not standardized, so that the readings are of little value ; the freezing point of water was at about 70', whereas 25' was reached on a hot summer's day ! Rye lived near Cork, and it is remarkable that the earliest Irish rainfall measurements were in the same area. They were made by Dr. Timothy Tuckey in the years 1738 to 1748, but they also are not comparable with modern measurements.In the second half of the 18th century the centre of activity moved to Dublin, and by 1753 temperature readings for Dublin in degrees Fahrenheit

In the course of a general study of the frequency of occurrences of aurora in Scotland during the years 1858–1938 a well‐marked period of length about 27.3 days was found to exist. Commander W.R. Priston has found a similar period in other meteorological elements, and it was his work (not yet published) which prompted the present investigation. The period is more than the well known 27‐day recurrence observed in many magnetic and associated phenomena, since that usually continues for only a few solar rotations, whereas this period has persisted for 80 years. The data used in this investigation were simply the dates on which aurora was seen from one or more of the meteorological stations in Scotland, including Orkney and Shetland. From 1858 to 1919 these are available in the Journal of the Scottish Meteorological Society and since 1924 they have been included in the Lerwick section of the Observatories' Year Book. For the intervening years the Reports of the Registrar General for Scotland were consulted, the required information being included in the meteorological notes appended thereto. In a few cases, chiefly in the earlier years, the original climatological returns have been referred to. This was necessary when the published information was indefinite, for example “Aurora was seen on nearly every night in October.” There were 5224 nights on which aurora was seen, an average of 66 nights per year and 5.1 per 27.3‐day period. The number of nights varied from 161 in the year July 1869 to June 1870 to five in 1912–1913.
