CARUM BULBOCASTANUM (L.) Kooh. 
This plant was used in India to protect clothes and skins against 
the ravages of insects .--Kirtikar and Basu ( 230 , v. 1, p. 622). 
CARUM CARVI L. Caraway. 
Oil of caraway was one of the best cures for scaly leg of poultry. 
It was applied in an ointment made of 1 part of the oil to 5 parts of 
white vaseline. This ointment should be rubbed into the leg and foot 
every few days until signs of the disease disappear.— Pearl and co- 
workers (304 , p. 222) • 
Carvacrol was tested against the body louse. A piece of cloth 
impregnated with the oil was kept for observation in a vial with lice 
on it. All of them were dead within 12 hours.— Moore and Hir6chf elder 
( 285, p. 55). 
Oil of caraway was sometimes sliphtly attractive but usually 
fairly repellent to the oriental cockroach.--Cole ( 101 ) . 
Acetone extracts of the seed killed 90 percent of the mosquito 
larvae tested.— Hartzell and Wilcoxon ( 188 ). 
CICUTA MACULA TA L. Spotted water hemlock. 
Extracts were not repellent to the Japanese beetle.— Mettger and 
Grant (277). 
CONIUM MACULATUM L. Poison hemlock. 
The action of coniine on the common blowfly was determined. Drop- 
lets of coniine were applied to various parts of blowflies, which with- 
in a minute showed signs of external irritation j there were rapid motions 
of the wings, and quick and aimless movements of the legs. The wings, 
as a rule, became completely paralyzed before the legs, and death oc- 
curred within 10 minutes to 2 hours.— Blyth and Blyth (64, p. 270). 
Spray solutions of coniine hydrochloride were tested against the 
bean aphid. The minimum concentration required to kill about 95 per- 
cent of the aphids was greater than 0.5 gm. per 100 cc, while that of 
nicotine sulfate was 0.009 gm.' — Richardson and Smith ( 322 ) . 
When coniine was tested as a contact poison, 1.0- and 0.75-percent 
solutions killed 90 and 60 percent, respectively, of bean aphids.— 
Tattersfield and coworkers (393). 
In laboratory tests coniine hydrobromide used ns a dust killed only 
25 percent of the codlinr moth larvae tested.— McAlister and Van Leeuwen 
(249).
