portal of entry into the body. Absorption through the skin is pos- 
sible. Frequently, on long exposures the chloride and neutral sul- 
fur content cf the urine increases, as does the acidity. Danger 
from fire and explosions frequently exists. The specific proper- 
ties and actions of a number of these compounds, including methyl 
bromide, are discussed in detail. No specific medical prophylaxis 
for chronic poisoning by this class of compounds is known,

Methyl bromide used successfully to fumigate plants in soil beds. 
Eort. Topics 3 (6): 11. 19 39. 
Experiments have shewn that emulsions made by adding 50 cc. 
of methyl bromide to 250 cc. of wood alcohol and diluting in 3 gal- 
lons of water will kill grubs of An or.-ala o riental i s Waterh. in 
azalea beds both in the greenhouse and outdoors. Examination made 
7 days after treatment revealed that all the larvae were either 
dead or disabled, but the azalea plants were not injured.

attacking azalea plants. Jour. Icon. Ent. 33: 486-490. 1940. 
Fumigation of soil and azalea plants in raised benches and 
floor benches by confining methyl bromide under a fumigating box 
at the rate cf 1 cc. per square foot caused no injury to plants in 
spring tests and only slight leaf burn to one variety in fall tests 
Soil temperature ranged from 54° to 81° F„ A complete kill of 
grubs of Anomala crientalis 7/aterh. was obtained in all tests ex- 
cept those conducted when the soil temperature was 54° at a depth 
of 8 inches and 58° at 4 inches. 
Fumigation of soil by injecting at 6-inch intervals methyl bro- 
mide and methyl or ethyl alcohol (1:15) at a rate of 0.5 cc. of 
methyl bromide killed most of the grubs and caused little or no 
injur},' - to plants. 3y diluting this solution with water and sprink- 
ling ever the area to be treated, a nearly complete kill of the 
grubs could be obtained without injury to plants, when 1 cc. of 
methyl bromide per square foot was used; 0.5 or 0.75 cc. gave less 
than 50 percent kill.
