The Treatment of Phthisis by Carbonic Acid

1890 Science  
infectious nature of fibrinous pneumonia, essentially confirms what is known of Fraenkel's pneumonococcus, and has also succeeded in proving the influence of cold as a factor in the origin of fibrinous pneumonia. According to the Lancet, the endotracheal injection of pneumonic sputa or plepritic exudation of animals which had died from pneumcnococci gave a negative result; but when the author, before cr after the endo-tracheal injection, exposed the animals to cold, the result was very

The authoi supposes that the cold paralyzes the ciliated ephithelium of the bronchi, and at the same time causes the mucous membrane to swell, both of which pathological processes favor the descent of the infectious material into the alveoli. These experiments were doubtless undertaken with a view to harmonize the old and new teaching upon the origin of this prevalent disease. A Long Fall. A remarkable fall of a miner down 100 metres of shaft (say, %33 feet) without being killed is recorded by M. Reumeaux in the Bulletin de l'Industrie Minirale. Working with his brother in a gallery which issued on the shaft, he forgot the direction in which he was pushing a truck: so it went over, and he after t, falling into some mud with about three inches of water. As stated in Nature, he seems neitber to have struck any of the wood debris, ncr the sides of the shaft, and he sbowed no contusions when he was helped out by his brother after about ten minutes. He could not, however, recall any of his impressions during the fall. The velocity on reaching the bottom would be about 140 feet, and time of fall 4.12 seconds; but it is thought he must bave taken loinger. It appears strange that he should have escaped simple suffocation and loss of consciousness during a time sufficient for the water to have drowned him. Tight Collars and Vision. The influence of tight collars in impeding the circulation in the head by pressing on the jugular veins is well-known to military surgeons with the troops in India, says the London Lancet; but the bad effects of such pressure in cooler climates have been demonstrated by the observations of Professor Forster of Breslau, who states that three hundred cases have come under his notice in which the eyesight has been affected by the disturbance of the circulation caused by wearing collars that were too small. A large number of these cases were probably
