The treatment is descriptionbed. It is suggested that cases of the vomiting of pregnancy are in a state of hypertonus of the sympathetic nervous system, and that this is concerned in the etiology of the disease. Evidence is given to support this hypothesis. Some of the actions of drugs which stimulate the parasympathetic nervous system are given. It is suggested that eserine sulphate, being one of these drugs, should diminish a state of sympathicotonia. It is thought that sympathicotonia plays a similar role in eclampsia, hypertention and albuminuria. Evidence is given to justify this supposition and warrant further investigation into the influence of the autonomic nervous system on the toxaemia, of pregnancy.
Variation in the number of testes in adult male schistosomes shows the difficulty in distinguishing the closely-allied species whose identity is more readily determined by consideration of the shape of ova escaping from the adult female worms. Adult male schistosome in uncommon situation such as the eyelid suggest the possible presence in South Africa of the schistosome which normally attacks the nasal veins of Indian stock, but confirmatory experiments are needed hefore their identity. can be established, as others are needed to confirm the accusation that only occasional hosts are to be regarded a important carrier of parasitic infection.
