Doctors Roux, Grancher, Metchnikoff, and Chamberland all had the privilege of sharing Pasteur's labors during the later years of the master's life, and each of them is a worthy follower of the beloved leader and at the same time a brilliant original investigator.*1* Roux is known everywhere in connection with the serum treatment of diphtheria, which he was so largely instrumental in developing.
The Channel coast towns of England are full of human derelicts who stand or sit for hours, looking wistfully back toward what was once home. The story of the hospitals is not always gloomy. Where the surroundings are favourable, defeat is sometimes turned to victory. Tetanus is being fought and conquered by means of a serum.
Liebig believes himself to have found the solution of this vexata quæstio in a class of chemical actions in which scarcely any less acute and penetrating inquirer would have thought of looking for it. Blood is composed of two parts, the serum and the globules. The serum absorbs and holds in solution carbonic acid in great quantity, but has no tendency either to part with it or to absorb oxygen.
The doctors told us that the Germans have a cheaper and better way to fill France with tuberculosis than by wasting serum on their enemies. And then, one day in a tuberculosis hospital we picked up this story, which explained what the doctors meant. We met a young man from Lille. It was his birthday; Henry bought him a bouquet. He told us his story.
Paper, dipped in the serum of the blood and dried in the same manner as in the urine, did not scintillate when the flame was blown out, but burnt exactly in the same manner as the same paper dipped in the serum of blood drawn from another person. This experiment, which is copied from a letter of Mr.
The disease still went on, and a fortnight afterwards a similar quantity was withdrawn. Various remedies were tried in order to check the power of the disease, but without effect, and the abdomen again became as much distended with the effused serum as before.
He learned that all but those who were cos-ata-lu came up cor-sva-jo, or from the beginning. The egg from which they first developed into tadpole form was deposited, with millions of others, in one of the warm pools and with it a poisonous serum that the carnivora instinctively shunned.
"The antitoxin to abrin," he replied. "I developed some of it at the same time that I was studying the poison. If an animal that is immune to a toxin is bled and the serum collected, the antitoxin in it may be injected into a healthy animal and render it immune. Ricin and abrin are vegetable protein toxins of enormous potency and exert a narcotic action.
Is this fair and manly argument, and can it have any other effect than to increase the scepticism of those who doubt? Here this note ends. The next begins upon the words "blood and water." "It is scarcely possible that the separation of the blood into placenta and serum should have taken place so soon, or that if it had, it should have been described by an observe as blood and water.
Others had told us that the real word was serré, meaning compressed curds; but the French writers who treat learnedly of cheese-making in the Annales de Chimie adopt the form sérets; and in the Annales Scientifiques de l'Auvergne I find both seret and serai, from the Latin serum.
