The mouse : kilogram-body-weight-sheep ratio is as follows: Cl. septique 1:17.5, Cl. welchii, Type B 1:60, Cl. welchii, Type D 1:12.5 and Cl. oedematiens 1:100. The last ratio was arrived at by the use of only six sheep and is thus approximate.en©South Africa, Dept. of Agricultural Technical Services (original). ©University of Pretoria, Dept. of Library Services (digital).Veterinary medicineVeterinary medicine -- South AfricaArticle
