THE BREEDING OF MOSQUITOES IN ALKALINE 
WATER. 
By H. L. Batiowe. 
Dr. C. S. Ludlow has sent the following note, quoted from a 
letter from Dr. H. L. Ballowe, Captain in the Medical Reserve 
Corps, U. S. Army at Fort St. Philip, Louisiana: 
**A neighbor of mine at Buras, near the post, prepared a mixture 
of caustic soda to kill the San José Scale on his orange trees. After 
using a part of the barrel of the solution, the rest was left in a semi- 
protected location for about eight months. It was exposed to 
the weather and to some rains. On examining this barrel one 
day I found it teeming with larve and pupe, both Anopheles and 
Culex. The alkali of the solution was marked to the taste, the 
color was a dark brown, and the solution affected litmus paper. 
I procured several jars of this solution and allowed the pupe to 
complete development. The adults were seemingly normal.”
