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 Forest, 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 Lower 
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. For some unexplained reason, however, their 
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.
