1423. The situations of the moon favourable to bad weather are the perigee, new and full moon, passage of the equator, and the northern lunistice. Those belonging to the former are, the apogee, quadratures, and the southern lunistice. Changes of the weather seldom take place on the very days of the moon's situations, but either precede or follow them. It has been found by observation, that the changes affected by the lunar situations in the six winter months precede, and in the six summer months follow them.
