At the o!iliosition of 1879-80, I measured with the large filar-micrometer of our refractor, a series of groups of the diameters of Mars. These were reduced by Prof. Henry S. Pritchett, (now of Washington University, Saint 1,ouis) and were published in A. N. 2309. At the next opposition, I measured

โฆ Synopsis
The follon iiig ephemeris is founded upon the same elements as that for tlic preceding opposition, published i n the Monthly Koticcs of the l i . Astronomical Society ~0 1 . 3 9 p.468 f f , the adopted values of the incliiiation and node of the plane of the equator of Mars in rffereiice to that of the Earth being ioclination 360 260\ node 47.945, for 1Sso.0
The data of the ephcmeris are to be interpolated dircctli-for the times, for which the)-are required, the

Although mechanical means of measuring physical activity are available, they cannot provide information about the context in which such activity occurs. Therefore, direct-observation systems remain essential tools for studying physical activity. The Observational System for Recording Physical Activi
