(2) Filaria.—Thirty blood films were examined for filarial embryos—five only were positive.
(3) Faeces. Two thousand four hundred and seven specimens of faeces were examined for parasites and the typical cytological picture of bacillary dysentery. An interesting finding is that of a case of infestation with balantidium coli. This is the first time that this parasite has been reported from this laboratory. Unfortunately, it was impossible to obtain any information as to the place of origin of the patient owing to the fact that death occurred rapidly.
