## Abstract When a slug test is conducted in a highly permeable aquifer, a shallow pressure transducer in the well casing produces an oscillatory pressure head that is representative of the water level fluctuation, whereas a deep pressure transducer in the well casing yields an oscillatory pressure

Observations on the Reciprocal Influence

Observations on the Reciprocal Influence which Magnetic Needles Exercise over Each other, When Placed at a Given Distance within their Respective Spheres of Action, at Different Positions on the Earth; with Tables of Numerical Results Obtained at Separate Stations. Also a Method of Discovering Where Certain Local Influences are Acting on the Needle, from which may Be Obtained a Proportional Correction to Be Applied to Magnetic Observations in General.
