though some of the weevils did not die until the next day. All 
larvae within the grains were killed "by 24 hours' exposure to 1 
ounce per 100 cubic feet at 21° C. Even at the rate of 5 l/2 
ounces to 100 cubic feet for 24 hours, methyl bromide only slight- 
ly reduced the germinating power of wheat and other cereals.

Tests were carried out in Morocco to determine the action of 
methyl bromide on various fruits, vegetables, and plants exposed 
to 6-7 ounces per 100 cubic feet for an hour at 22°-26° C. A par- 
tial vacuum wa's maintained for 20 minutes, after which the pres- 
sure was brought back to normal, and the products were ventilated 
for 10 minutes after fumigation. Bananas became soft and black- 
ened, pears became soft without showing outward change, and pota- 
toes became brown and slightly soft, but none of the other fruits 
or vegetables were affected. Of 25 plants the only ones injured 
were Fuchsia , Ire sine, and Zant cd e s c hia , the leaves of which 
withered and dropped 48 hours after exposure. Susceptibility to 
methyl bromide appears to be related to the water content of the 
plant or fruit, A series of tests showed that the hydrobromic 
acid given off by methyl bromide in a saturated atmosphere does 
not exceed 2 parts per 1,000 if the fumigation is of normal 
duration.

A further report is made on a case of methyl bromide poison- 
ing first reported by Opperman ('see reference 95), in which there 
were repeated epileptiform attacks for 2 years, and even after 4 
years there was some nystagmus and feeling of discomfort. Two 
new cases are reported, of which one was fatal. Both men were 
exposed at the same .time, but the one who died had been exposed 
repeatedly previously.

All the larvae of (Cydia) Grap holitha mojh^sta (Busck) and 
Carpocapsa pomon clla (L.") in pears exposed to 15 gm. of methyl 
bromide per cubic meter for 18 hours were killed. No injury to 
the fruit from methyl bromide was observed. In French crab 
apples, however, the type of injury described by Phillips and 
coworkers (100) was found.

A fatal case of methyl bromide poisoning is reported. There 
was an interval after exposure before the onset of any symptoms.
