Four out of five of those who have an arm or a leg amputated die of pyaemia.

Now, as in the American tents four out of five recover; and as French surgeons are as skilful as American surgeons, the average mortality in the two ambulances is a crucial proof of the advantage of the American tent system.

Under their tents there is perfect ventilation, and yet the air is not cold.

If their plan were universally adopted in hospitals, it is probable that many lives which are now sacrificed to the gases which are generated from operations, and which find no exit from buildings of stone or brick, would be saved.

"Our war," said an American surgeon to me the other day, "taught us that a large number of cubic inches of air is not enough for a sick man, but that the air must be perpetually renewed by ventilation." _December 24th._ The papers publish extracts from German newspapers which have been found in the pockets of the prisoners who were taken on Wednesday.
