Methods of digestion of fish samples for mercury determination by flameless atomic absorption spectrophotometry have been investigated. Digestion in Teflon bombs, Kjeldahl flasks, or borosilicate test tubes gives comparable precisions and mercury recoveries. Because of their cost and effect in limiting productivity, Teflon bombs were considered unnecessary for analysis of fish samples. Experiments with cooked and uncooked fish samples have confirmed that no appreciable loss of mercury occurs during baking 30 min at 170 degrees C.

From Kashmir to Burma, where tigers once lived amid lush forests, a vast tract of land has been laid bare by the timber industry. In its wake have come landslides, drought and yet further poverty. The only hope for the hill people is a Ghandian like movement which villagers have adopted to thwart developers.

Pushkar, near Ajmer, Rajasthan, lies in the dry zone to the east of the Indian desert. In the vicinity there is evidence for three arid phases, during the latter part of the Pleistocene, each represented by a major sand sheet and fossil desert dunes. The earliest contains lenses of detritus which include rolled Lower Palaeolithic tools.

This paper outlines a research proposal for a series of investigations into aspects of urban housing which it seems important to understand before formulating an enlarged public housing programme. Studies in the areas outlined here are either scanty or non-existent.

The years 1965 and 1966 will be remembered in Indian history as two successive years in which the failure of the south-west monsoon had a disastrous effect on Indian economy. This article is an attempt to find out the basic causes of this large-scale deficiency in the monsoon rainfall.

It is widely assumed that a deficiency of immune function underlies the coexistence of viral excretion and specific-antibody production in patients with congenital rubella. Recent demonstrations of lymphocyte viræmia, and of lymphocyte competence for response to phytohæmagglutinin, have made this assumption more questionable. Whether or not the cellular immune system is unresponsive to rubella virus, cellular viræmia can be expected to continue for the lifespan of the infected cell.

The procedure outlined describes an extremely sensitive and accurate method for the determination of mercury down to 1.0 ppb in solution. This procedure has been applied to nickel and cobalt metal as well as rock samples and soil samples containing organic materials.

Bihar is a predominantly agricultural State with 86 per cent of her population depending upon agriculture. In my study of the National Income of Bihar published in the Indian Journal of Economics, July 1951, I had estimated the gross agricultural income of Bihar for the year 1846-47 at Rs. 230 crores, basing myself on the statistics published in the Season and Crop Report, and at Rs. 272 crores when based on the statistics contained in the Crop Survey Report.

The S.W. monsoon or summer monsoon is a major event in the agricultural life of India, which has been widely studied. The chief characteristic of the pressure distribution over India during the monsoon is the trough of low which extends from the the S.E. Punjab to the head of the Bay and the concomitant high pressure belt in the Indian Ocean.
