摘要:

The frequency of sequences of consecutive days without rain and with rain at each of the above-named meteorological stations has been determined from their records of daily precipitation for the months April to September of the years 1916 to 1937. It is inferred from these frequencies that rainy or rainless days do not in general occur entirely at random, but that the same kind of weather tends to persist over successive days. The statistics have also been used to estimate the expectation of rainless periods. At all three stations, this is least in mid-summer (June and July) and greatest in spring and autumn.

摘要:

A summary is presented of correlation studies based on data, for 11 barley properties and 7 malt properties, obtained by analysis of samples of 12 varieties of barley (and of the malts made from them) grown at 12 experimental stations in Canada. Intra- and intervarietal associations between pairs of properties were studied separately using means over all varieties for each station, and means over all stations for each variety. Simple correlation coefficients for all possible pairs of properties are reported. In addition, intravarietal partial correlation coefficients, independent of total nitrogen, and intervarietal partial correlation coefficients, independent of salt-soluble nitrogen, are also given.The main purpose of the paper is to put on record, for ready reference, tables of statistics that may be useful to other investigators who are interested in the associations that exist between barley and malt properties, and the light that these throw on the nature of malting quality in barley.

摘要:

Plankton collections from 58 lakes of the Prince Albert Park and the southern half of Saskatchewan yielded 292 species and varieties of algae, among themChaetoceros Elmorei,Nodularia spumigena, and a new variety ofLyngbya Birgei. The lakes, chemically alkaline, are classified as freshwater and saline, and the various classes of algae are briefly discussed with reference to these two types of lakes. A list of the species collected is given, showing localities and relative abundance of each type.
