Not only so. Their surgeon-general, the great Stromeyer, condescended to inspect our hospital, and complimenting the Chief on its details and management, invited him to visit his own Ambulance at Floing. Dr. MacCormac did so, and was highly pleased with all he saw. The success of the Prussian surgical operations was very striking. It contrasted most favourably with our results; but this depended, in great measure, on the Floing Hospital having been a temporary structure, consisting of improvised shanties, boarded all round in such a way that the sides could be opened at will in louvre fashion, so that, weather permitting, the patients were treated practically in the open air, yet without subjecting them to chill or exposure. I conceive that this was the explanation of their low death-rate, for the surgical methods of procedure were identical with our own. And I may anticipate here a remark which my experience at Orleans afterwards confirmed, _viz._, that such open-air treatment is the only effective protection against blood-poisoning. This was the first introductory step to our transition from the French to the German side, but the change was slow and gradual. Hints, indeed, were constantly thrown out that our services would be well received, if we followed on in the track of their army. At first we firmly asserted our neutrality. But we were made to understand that the attitude we had assumed was impracticable; we must make up our minds to be on one side or the other. These warnings did much to determine the line of action upon which we finally resolved. Our movements were also influenced by the fact that while, as regarded the majority of our staff, our sympathies were undoubtedly French, yet later on, when we came in contact with the Prussians, and got to know them thoroughly, the admiration with which we started for the other side was very much cooled down. We looked on the belligerents with less prejudiced eyes, and, in the long run, had no decided leaning one way or another.
