Focusing on developments in the Madras presidency between the Rebellion of 1857-58 and independence 90 years later, this book studies the creation of a British constabulary in India as a powerful coercive tool of British colonialism. The author targets the use of police force against dacoits, nationalists, adivasi hillmen, and urban proletariats, and reveals, through the organization and social composition of the constabulary, how internally as well as externally, the police force mirrored the underlying character of the colonial system as a whole.

Significant variations in the 72 to 200 kilo electron volts gamma ray energy interval were recorded, providing a unique data base for very low energy gamma ray astronomy. Interpretation of the variation observed in terms of sources in the gamma ray sky was studied. The methods of data analysis extend the procedures used in hard X-ray and soft gamma ray astronomy to the case of an extremely large field of view. Exposures were calculated for both point sources and extended sources. A system of equations was established which expresses the counting rate as the sum of the strength of the sources weighted by the exposure. This system was inverted by a weighted-least-squares procedure to determine the source fluxes from the observed counting rates.
