Note. — This ends the list, which, however, is probably in- 

 complete, for local maps exist in the chests of the Ordnance Sur- 

 vey and of great estate offices that are not accessible to the 

 public. At least it may help an enquirer and present a nucleus for 

 addition. 



The Atlases and Maps enumerated above may be seen at 

 the British Museum. There is an excellent collection of Dorset 

 Maps at the Dorchester Museum ; a few Hampshire and Dorset 

 maps at the Central Public Library, Bournemouth; a few port-

MOSQUITOES and MALARIA in ENGLAND. 



Abstract of a General Lecture by 

 F. W. Edwards, B.A. 



(Delivered at the Municipal College, December 4, 1918.) 



]\ /TALARI A is an infectious, but not a contagious disease; it is not 

 carried from person to person by direct contact but only 

 through the agency of certain blood-sucking mosquitoes, the para- 

 sites which cause it undergoing an essential part of their life history 

 in the mosquito's stomach. It was at one time very prevalent in 

 the more low-lying parts of England, but in the latter half of the 

 last century had entirely disappeared. However, although the 

 disease itself had died out, the mosquitoes, which were concerned 

 in spreading it — the same insects which still play this obnoxious 

 part in the Mediterranean region — still continued to exist amongst 

 us. There was, therefore, always a danger lest the introduction 

 into this country of any considerable number of persons suffering 

 from Malaria might cause a renewal of epidemics of the fever. 



This danger, owing to war conditions, has now been realised, 

 and during the last three years about 600 cases of Malaria have 

 occurred amongst persons who have never left this country. 



With the return in the near future of large numbers of soldiers 

 who are suffering or who have suffered from it the danger of 

 more serious outbreaks must be faced. Such being the case, it is 

 most desirable that the public should obtain more detailed know- 

 ledge of the nature of the disease and of the methods of its pre- 

 vention, and act on this knowledge when and as required. 

 Since the malaria parasite undergoes one part of its life history in 

 human blood, completes its development in a mosquito's stomach 

 and can only infect a healthy person through the bite of an
