rrot readily soluble, and it breaks up slowly in the presence of 
humidity, forming hydrogen "bromide. Its use in the fumigation of 
vegetable substances with an appreciable humidity content but not 
a continuous cuticle is therefore inadvisable. Excellent results, 
however, have been secured in the treatment of pears, the color 
and consistency of which remain unaffected, and for which ethylene 
oxide is unsuitable.

Recent patents are reviewed on processes dealing-with the 
veneration of methyl alcohol from water e'as, direct oxidation of 
methane to methyl alcohol, manufacture of methyl chloride and 
bromide from methane, and the oxidation of these to methyl alco- 
hol and the manufacture of methyl alcohol from carbon monoxide.

Early symptoms of methyl bromide poisoning are headache, 
weakness, vertigo, vomiting, and some disturbances • of vision. The 
gait may be staggering, and slight pain in the extremities and 
neuritic symptoms may be noted. After several hours or even days, 
severe symptoms may appear in the form of strong contractions of 
different groups of muscles, clonic spasms of the entire body, 
double vision, pareses of the extremities, sleepiness, and poly- 
neuritis. Convulsive type of' respiration may be noted, and in 
the fatal cases reported epileptiform attacks are merged into a 
terminal coma. Physical signs of pneumonia may be noted. Con- 
valescence is slow.

Tests we're made on the control of Tarsoncmus pal lidus Banks 
(T. fragariae Zimm, ) with a number of fumigants, including a Swiss 
preparation called S-gas, This is supplied in a liquid form in 
ampules, its active constituent being methyl bromide. Methyl bro- 
mide is a rather violent respiratory poison, but is easy to apply 
with safety to strawberry runners, which can bo fumigated in any 
tightly closed metal box in which the ampule is broken. A 
strength of 2 percent by volume killed all the mites and eggs in
