an insidious, lingering disease, probably insect-borne , which he 

 contracted during his expedition to Brazil. Its nature baffled 

 the medical specialists until Mr. Knab himself correctly diagnosed

 languages, and was a broad student. He was noted for his 

 helpfulness to other workers, and for his genial, companionable 

 nature. He was a very active member of the Entomological 

 Society of Washington, attended the meetings regularly as long 

 as his health permitted, frequently contributed papers, and often 

 added great interest to the discussions. His interest in the Society, 

 in fact, was so great that he bequeathed the larger part of his 

 estate to it an especially noteworthy act, as this is the first 

 considerable contribution to the publication fund of the Society.
