(Summary) Various compounds were tested as to their effectiveness at a distance in inhibiting mosquitoes from biting a shaved belly of a rabbit. Known skin repellents were ineffective in repelling mosquitoes at a distance, as were also "space repellents" obtained from the USDA; some compounds of higher volatility were relatively effective. Chloral, diisopropylamine and diethylamine were effective to a distance of 9.4 cm (the maximum distance tested) and acetic acid to 4.7 cm. Other compounds were variously less effective.
