SECOND REPORT ON ECONOMIC ZOOLOGY. 



BRITISH (pp. 3 to 110). 



GROUP D. 



Animals which concern Man as causing- bodily injury, some- 

 times death, to him, and in other cases disease, often of 

 a deadly character. 



Mosquito annoyance at Woodford (Essex), and 



elsewhere. 



During the past summer mosquitoes have been very prevalent in 

 Essex, especially in the neighbourhood of Epping Eorest, and also in 

 Kent and Surrey, notably along the valleys of the Thames and 

 Kennet, and in the wide stretches of marsh land in the Lea and I;Ower 

 Thames Valleys. 



They have also been reported to the Board of Agriculture as 

 being most annoying near Bristol, and similar complaints have been 

 sent me from Great Staughton, in Huntingdonshire, Weston-super- 

 Mare, Worplesdon, Colchester, Canterbury, and Birchington. 



Certainly there has been a greater amount of annoyance caused 

 by them this year than usual, but every year complaints are made in 

 the Thames Valley. Eor some unexplained reason, however, tlieir 

 bites have been more virulent than usual, in many cases causing 

 a considerable amount of oedema, which has necessitated medical 

 attendance. In many instances where people have been bitten on 

 the face the swelling has been so great that the eyes have been closed 

 up for some days. The medical officer for Leyton states that scores 

 of instances of serious bites have come under his personal observation.
