Materials and methods

Test guideline
Qualifier:
no guideline available
Principles of method if other than guideline:
Six animals were given a single dose. After one week another 6 animals were given some other dose until two doses were found, differing by a factor of ten, where in one dose all animals died and in the other only some or no animals died. Post exposure period was 14 days. (see Smyth & Carpenter 1944)
