sketches. He also showed great care and critical judgment 

 in the field experiments and observations that he carried 

 out at Ballyhaise. The results of these were published last 

 autumn in this Magazine/ and more fully in a Report" for 

 the Department's Journal. By patient and long-continued 

 watching, Hewitt was able to see the tiny newly-hatched 

 Hypoderma-larvae bore into the skin of cattle, and thus to 

 settle a question which had been disputed among agricul- 

 tural entomologists and veterinary surgeons for twenty 

 years. In the intervals of his work on this subject, Hewitt 

 dealt profitably with other insect -studies such as the Larva 

 and Puparium of the Frit-fly^ and the hibernation of the 

 Woolly Aphid in apple -cores. A valuable report on Eel- 

 worms in Narcissus bulbs,^ the result of much careful 

 observation and field experiment contains further results 

 of his activities, and a bye-product of this last enquiry 

 was the discovery of several species of Nematoda^ new to 

 Ireland. 



Such a record of two and a half years shows Hewitt's 

 capacity for research, and moreover he voluntarily shared 

 in some of the teaching of the zoological laboratory. We 

 who knew and valued him looked forward to a prolonged 

 association in the work that he did so well. It was the 

 more praiseworthy, because he was frequently hindered by 

 ill -health, and his brave habit of " making the best of 

 himself " appealed to all. His cheerfulness and trustworthi- 

 ness won the affection of his fellows, as his talents moved 

 their admiration. And even now as we reahse the loss we 

 have suffered through the sudden removal of our friend, 

 his faith, his hope, his devotion to duty speak to us from 

 the silence, and help to lighten our way.
