In 1831, his enemies took a bolder course, by raising an alarm of the craft being in danger. This enlisted in their cause the medical men at Vienna, who brought the subject under the notice of the emperor. He sent Dr. Baron Turckheim with a commission of district and staff surgeons to Gräfenberg, to investigate and report on the new system, and the proceedings of its originator. Notwithstanding that most of these gentlemen were prejudiced against both, they were astonished and pleased at what they witnessed; and their report was of so favourable a nature, that Priessnitz was allowed by imperial authority to carry on his establishment, with the addition of the privilege enjoyed by staff surgeons of giving sick certificates to public employés and officers under his care. This state of things was, however, again shortly afterwards disturbed. In 1835, the emperor Francis being dead, fresh intrigues induced the government authorities at Troppau (a town about fifty miles from Gräfenberg) to withdraw the permission Priessnitz had received for giving sick certificates. He was urged to appeal to the higher powers, but declined, saying--"The matter must right itself," and steadily refused giving sick certificates, even to foreign officers. These complained, through their ambassadors, to the authorities at Vienna; and for them, Priessnitz's power of granting certificates was restored. The Austrian officers and employés being still excluded, also exerted themselves through friends in the capital; and the matter was, in the end, satisfactorily arranged. In 1843, the Prussian government, doubtless under medical influence, forbade all officers or employés proceeding to any hydropathic establishment out of Prussia, unless expressly recommended by their medical advisers. The greatest difficulty in obtaining passports to the Hygiean temple is also encountered by the Russian Poles. It has been observed by many from both these countries who, nevertheless, reached Gräfenberg, that their medical men strongly recommended their not going to Priessnitz, and willingly gave certificates for any other establishment, even though in a foreign country. For thirty years, although all publications against Priessnitz and the Water-cure were tolerated in the Austrian dominions, none in favour of either were permitted. But, as though willing to do tardy justice and urged on by public opinion, in July, 1845, the Vienna Gazette inserted a favourable article on both subjects.
