the derris lotion consisting of 4 ounces of derris powder, 1 gallon 
of water, and 16 teaspoonfuls of soap flakes. Six applications to 
the body three times a day for 2 consecutive days cured practically 
every case. It was the most effective method,— Saunders (520 , 521 ),

All but 3 of 50 cases of soabies were cured by one application 
daily of a lotion containing 4 ounces of derris powder to 1 gallon 
of water and 18 drachms of soft soap. No dermatitis or other un- 
favorable sequelae were reported,— Stuart (675 ), 
Rotenone in the form of 1 or 2 percent lotions, with a base 
similar to that of many hand lotions (quince seed, Irish moss), pro- 
duced prompt cure of scabies in 24 unselected cases encountered in 
clinio and institutional practice,— Thomas and Miller (590) , 
Ninety percent of the cases of scabies on soldiers were effec- 
tively treated by one application of an ointment containing 10 to 50 
percent of Lethane or pyrethrum, or derris extract at concentrations 
ranging from 0,6 to 1,8 percent of pyrethrins, and 0,5 to 2.5 percent 
of rotenone. The remaining cases were cured by a second application,
