• The annual growth rate of <I>Calapoecias</I> was measured from the figures given by several authorities in a previous work with the view of find the Ordovician climatological conditions of the Arctic regions as well as several European provinces. In the present article, emphasis is laid on the development of seasonal change and annual length in growth of a number of tabulate corals as a further detailed study on the climate of the northern hemisphere during the Ordovician period.
