Although preparations of copper are not now much used in this affection, I can refer to some very good results from the sulphate in my own experience, and especially in cases connected with taenia and other intestinal worms. I think it well worthy of use in cases where there is even a suspicion of their existence; it will aid their expulsion if present, and in any case act as a good nervine tonic. I have seen permanent good results from 1/4 gr. given three times daily, though sometimes this dose needs to be gradually increased.
