systematic and biological facts and principles. No such work had 

 hitherto appeared. 



Tutt was remarkable for the facility with which he seized and 

 comprehended his facts, and the rapidity with which he arrived 

 at sound conclusions upon them. He had a remarkable power of 

 obtaining the co-operation of others in his work, and was always 

 willing to assist other workers. Eager as he was to learn, he was as 

 anxious to spread the knowledge of the facts and conclusions he had 

 obtained, and was always ready to denounce errors due to faulty 

 observation or to traditions without any sound basis. 



His abounding energy and constant activity both in the field and 

 in the closet were marvellous. He no doubt overworked, and this 

 assisted by East End air and a long-standing heart weakness probably 

 led up to his fatal illness.
