A verylarge sunspot of great complexity and intense activity was under observation from February 24 till March 6 and. owing to very favourable weather conditions, eight detailed sketches were made showing the progressive changes. Fairly large sunspots were also observed during the middle of Apil, and at the end of October. As the result of circumstances beyond control, no observations were made during the periods from September 7 to 18 and November 15 to December 15, and in this respect the year's record is incomplete.
