The following suggestion is worth knowing for anybody who has a bilious headache and is obliged to make a speech, or any great effort. Put a whole tin of Colman's mustard into a large hot bath, stay in it ten or fifteen minutes, lie down after it for half an hour. The brain will then be far clearer and better than in ordinary health. This is a remedy only to be used for an emergency. It is, of course, rather a severe trial for the circulation, but less likely to be injurious than the drugs which are so often taken for headaches.
