The observations
10. The following table exhibits the rainfall in Hongkong for about 40 years. were, from January 1853 till March 1862 made by the Royal Engineers. From January till April 1853 the gauge was 20 feet above M. S. L. and very near the ground. From May 1853 till April 1855 it was 20 feet above the ground. From May 1855 till October 1857, it was 100 feet above "M. S. L. and very near the ground. In November and December 1857 no observations were made. Mean values have been entered. From January 1858 till March 1862 it was 35 feet above M. S. L. and 20 feet above the ground. From April 1862 till December 1864 and also in September 1874 the observations were made in the Government Civil Hospital. From 1865 till 1883 they were made by the Army Medical Department, and from 1884 till 1891 at the Observatory. From January 1865 till May 1877 the gauge was very near the ground and 43 feet above M. S. L. From June 1877 till December 1883 it was 18 feet above M. S. L. and very near the ground. Since 1884 it was a foot above ground and 108 feet above M. S. L.-If the figures were accurate the value of this table would be great. It appears that there is a little more rain when there are many spots on the Sun than when there are few, but the difference is too slight to be of any practical importance. After the end of April. there is always plenty of rain up to the end of August, but then the rainfall decreases quickly as a rule, and as it is moreover extremely variable during September and October, these months should be watched. When rainfall is defective in both months à drought may occur during the following six months, though it is sometimes prevented by heavy winter rains:-
