Amoebas eat algae, bacteria, plant cells, and microscopic protozoa and metazoa – some amoebas are parasites. They eat by surrounding tiny particles of food with pseudopods, forming a bubble-like food vacuole. The food vacuole digests the food. Pathogenic free-living amoebae are found in many natural and human-made microenvironments, mostly living by bacteria feeding. However, in certain situations they can cause serious infections in humans.

In 1817, James Mill, a Scottish economist and a political philosopher, published A History of British India in three volumes. He divided Indian history into three periods—Hindu, Muslim and British. It has been argued by many historians that it is not correct to periodise Indian history on the basis of religion of the rulers. For example, when the Hindu kings ruled in ancient India, many religions existed peacefully. The same is also true for mediaeval India. It was not correct to periodise mediaeval India as Muslim History because people belonging to different faiths existed during this time. Such periodisation which was based on the religion of the rulers suggests that the lives, practices and culture of the other people do not matter.

Under Lord Hastings a new policy of “paramountcy” was initiated. Now the Company claimed that its authority was paramount or supreme, hence its power was greater than that of Indian states. In order to protect its interests it was justified in annexing or threatening to annex any Indian kingdom. This view continued to guide later British policies as well.
