shady and damp woods, in trees, huts, dwelling-houses, stables, & c. 
and it is only at night that they come forth from their hiding-places 
to bite man. When there is much wind they usually do not 
venture forth from their hiding-places. They never fly far from 
the place where they are hatched, and they do not rise to any great 
distance from the ground. Blood-sucking is an acquired habit 
of these insects, and there are several others of the Diptera that 
display the same propensity. 
Quito recently, Messrs. Nuttall, Cobbett, and Strange ways-Pigg 
have made extensive observations upon the distribution of 
Anopheles in England, and they have produced two maps, one 
showing the former distribution of Ague anil the other the dis- 
tribution of the Anopheles. From these maps it is seen that there 
is a very striking similarity between them. From the Ague map 
you will see that formerly Malaria was known to exist in many 
places in East Anglia. In Norfolk there is evidence to show that 
cases have been recorded from Lynn and the neighbourhood, in 
which district severe Ague was prevalent in 1844. At Wells it 
was formerly frequent, and at Walsingham there were cases 
in 1859. It doubtless also was prevalent in many other parts of 
the county, especially in the marshland and broad districts. In 
the fens, the so-called Fen-Ague has been known for many years, 
though it is much less common than formerly. In a recent 
communication from Dr. Galletty of Northwold, about a case 
1 heard of in that district, he says : “It was the only case of the 
kind (Fen-Ague) I have seen since I came here seven years ago.” 
There were nineteen cases of Ague treated in the Norfolk and 
Norwich Hospital from 1820 to 1860. During the five years that 
I have been connected with this Institution only one case has been 
admitted, and that from Acle in 1897. You see also that its 
previous occurrence is reported from many places around the mouth 
of the Thames and from the Iiomney marshes. Also in several 
isolated places in England. In his ‘ Tour through the Eastern 
Counties, 1722,’ Defoe says, in speaking of the Hundreds of Essex : 
“ I took notice of a strange decay of the sex here ; insomuch that 
all along this country it was frequent to meet with men that had 
from live or six to fourteen or fifteen wives ; nay and some more. . . . 
The reason, as a merry fellow told me, who said he had had about 
a dozen and a half of wives (though I found afterwards he fibbed
