Meanwhile Godowski himself had arrived at our apartment, much to the relief of our friend Johnson, and was unpacking his instruments.

Quickly he improvised two operating tables, and placed one of us on each. Then, with his assistant, he put on his white robes, mask, gloves and other precautions for asepsis, setting out the apparatus for the intravenous administration of the drug that would kill the spirillum. Godowski was busy with the atoxyl, mixing it in a normal salt solution. He would drop in a few drops of an acid, then a few drops of an alkaline solution, so as to keep the mixture neutral. Finally, he poured the solution into a container, to the bottom of which was attached a long tube. This container he raised high over our heads, clamping the tube.

Then he fastened a tiny needle to the end of the tube, so that it could be inserted in our arms, catching skillfully a vein—a very difficult piece of work in which he excelled. The liquid would then flow by the force of gravity from the container down through the tube, through the hollow needle and into the vein where it would act on the germs of the fever.

They had finished their preparations and were waiting for Miss Septix. "She ought to be here, now," muttered Godowski impatiently, looking at his watch.

Just then a cab drove up outside.

"Perhaps that is she," he exclaimed. "It must be."
