canal 2 larvae; on the Hazebrouck Road 4 other

Notes on Anopheline districts in France outside the Second Army Area. 
Anopheline larvae were found among a sample of many hundreds of Culicine 
larvae sent by Capt. Wadsworth, R.A.M.C., from Serqueux. The pond from 
which they were obtained was in close proximity to a malarial segregation 
hospital. The specimens were collected on August 22nd, 1918. At Abbeville 
between August 22nd and 25th, 1918, were found 3 large Anopheline 
ponds and one water channel in the Faubourg Thuison, one of the ponds 
containing numerous larvae and the other two containing few, while the 
channel also yielded few. Larvae were also found in the marginal vegetation 
of a stream running through the Triage (goods station) and at Mautort, some 
3 miles outside Abbeville, 3 large Anopheline pools were discovered, one 
with numerous larvae and 2 with few.
