An Atlas of Rectal Endosonographythus botany has been distinct from zoology intellectually and sometimes in geographical location as well. During recent years welcome changes have been initiated in the direction of a more interdisciplinary approach, beginning in the schools under the influence of the Nuffield Projects and spreading

They exist both in regions influenced by industrial pollution and in others which are essentially unpolluted.

An Atlas of Mammalian Chromosomesn genetics. The haemoglobinopathies remain a valuable tool for the study of gene action in Man but in the last few years the emphasis in this field has changed from population genetics to the study of abnormal haemoglobin synthesis at a molecular level. This trend is particularly noticeable in recent work on thalassaemia.
