DR. ERKKI MIKAEL MIKKOLA, geologist of the Geological Commission of Finland, was killed at Taipale on February 13. Mikkola, who was born in 1907, had become a leading authority in Pre-Cambrian geology, possessing an intuitive faculty of seeing through a geological formation, and picturing it correctly in space and time. His scientific studies led him from botany to geography, quaternary geology, tectonics and petrology. His three Lapland maps are given a foremost place among. Pre-Cambrian sheets of the Finnish Geological Survey. Their description in English is a monograph of fundamental value.
