The unusually early appearance of Hypoderma lineatum in the subdermal tissue 
in the backs of cattle in Texas is noteworthy. In certain sections of the plateau 
region the larvea were fully developed about the middle of August. In the vicinity 
of Dallas the appearance of larvae in the backs of cattle is about one month earlier 
than normal, considerable numbers being present during the latter part of September. 
Under favorable weather conditions it is almost certain that a rather large emergence 
of the adults of this insect will take place during the fall and early winter months. 
Dengue fever has been reported from the southern states from Georgia westward. 
The first case reported for Georgia was in the week ending October 12 and no cases 
have been reported from Florida. It is noteworthy that although the disease ap¬ 
peared rather early during the summer it did not gain great headway. This might 
be explained partially by the large percentage of immunes following last years epi¬ 
demic and partially by the relatively smaller numbers of the yellow fever mosquitoes. 
This mosquito has been noticeably less abundant in Dallas than it was last year 
though this may not be the case throughout the South. 
The following is the number of cases of dengue given in the “Public Health Re¬ 
ports” up to and including the week ending October 26: 
Georgia. 8 
Alabama. 35 
Arkansas. 6 
Louisiana. 259 
Texas. 422 
According to Science, the Widow of the late Surgeon General William C. Gorgas 
is collaborating with Burton J. Hendrick, author of “The Life and Letters of Walter 
H. Page,” in preparing a biography of General Gorgas, which, it is hoped, may be 
published during the coming year. 
According to Science, The London School of Tropical Medicine has arranged to 
send an expedition to Samoa to study the prevention of elephantiasis and filariasis, 
diseases which affect 85 per cent, of the inhabitants of the Samoan group. The 
expedition will have its headquarters at Apia and will be away for two years; 
it will work in cooperation with the New Zealand government, which is responsible 
for the administration of Samoa. The expedition, which will leave England on No¬ 
vember 15, will be under the leadership of Dr. Patrick Buxton, who did valuable 
work on entomology in Mesopotamia during the war, and has recently been ento¬ 
mologist to the Palestine Government at Jerusalem.
