In May 1992, Banting and Best, working in the Physiology Department of the University of Toronto, obtained the first active extracts from pancreas. The credit for the preparation of such extracts capable of effecting a lowering of the blood and urinary sugar, and serviceable in mitigating the symptoms of experimental diabetes in animals, and o human diabetes, therefore, belongs to these two workers, to Waoleod and Collip. Improvements in the methods of extraction and purification of insulin followed quickly. Accompanying this were the investigations of the physiological, chemical and physical properties of the hormone. Since that time a mass of evidence relating to the above and produce by a host of workers has accumulated.

Experiments were conducted to determine the effects of cultural practices such as irrigation, planting date, and maturity group on soybean nectar production. Multiple interactions between different factors influences the amount of total sugar present in soybean flowers. Pod production was increased in later planted soybean, but later planting resulted in reduction in yield. Another study was conducted to explore the effects that variety selection had on soybean nectar production. Soybean nectar production was highly variable among varieties and was influenced further depending on their growing location. Later maturing varieties produced significantly more soybean pods. This increase in pod production was not reflected in yield, as the later maturing varieties usually yielded less.

The island of Mauritius is situated in the south-western Indian Ocean between 19°591, 20°321 south latitude and 57°18 1 , 57° 49 1 east longitude. The nearest landmass of any considerable extent is Madagascar which Iies some 900 km due west of Mauritius; but there are a number of islands and islets in the vicinity, notably Reunion, Rodrigues and the Cargados Carajos, which together with Mauritius constitute the archipelago of the Mascarenes.
