In Phthisis, it has been strongly advocated by Dr. J. Hastings and Dr. Hocken,§ who state that they were led to its use by observing, that tubercles obtained from patients who had died of Phthisis were completely soluble in it. The dose advised was exv., gradually increased till ezz - l. were taken, four times a day. The statements of these gentlemen were received with much doubt by the profession. Dr. Theophilus Thompson || has investigated the subject.

Excepting the above, it has no single beneficial effect on the disease.
