No. 22. SYLVESTER MEDAL FUND. 



Soon after the death of Professor J. J. Sylvester, F.R.S., in 1897, 

 a number of his friends considered the advisability of founding some suitable 

 memorial in honour of his name and life-work. The suggestion met with 

 a ready response from all parts of the world, and a powerful and represen- 

 tative International Committee was formed. A sum of nearly 9QQ was 

 subscribed, and it was decided to found a medal and prize for the encourage- 

 ment and reward of working mathematicians throughout the world. The 

 Council of the Royal Society undertook the trust conditionally upon the 

 medal being awarded triennially and irrespective of nationality. A medal, 

 accompanied by a grant of the balance of the Sylvester Medal Fund, is 

 accordingly awarded triennially for the Encouragement of Mathematical 

 Research. The fund is invested in ,795 16*. 5J. Local Loans Stock (see
