Abstract
TWO series of Research Bulletins which have -I recently reached this country from America provide remarkable examples of the laborious-one may almost say meticulous-methods which distinguish much of the work now being conducted at the Agricultural Experiment Stations in the United States. The bulletins in question come from the stations attached to the Universities of Missouri and Minnesota respectively. In both cases the aim was to find out by actual chemical analysis the constitution of the bodies of cattle at various ages. In the case of the Minnesota investigations, sixty-three bullocks, at all ages from three months to two years and over, were slaughtered and analyses made of the bodies, not merely as a whole, but under such divisions as flesh, offal, skin, blood, etc. In the case of the Missouri investigations, thirty animals were slaughtered and analysed in much greater detail. Separate figures for all descriptions of edible joints and for each organ of the body are given. It does not require much acquaintance with chemical routine to realise the extraordinary labour involved in reducing the separate parts of the body of an animal to a fine pulp from which uniform samples of every description of tissue can be drawn. So far as this country is concerned, the attempt has been made only once-by Lawes and Gilbert many years ago-and then with difficulty three animals in all were completely analysed.
