On the Use of Oxygen in the Treatment of Anæmia, with a Case Treated by Transfusion of Blood

John B., labourer, aged 38. complained of extreme weakness and of pains in the back. The family history was good. The patient had suffered from dyspepsia, but had never had any bad illness. The present illness began two years ago with a feeling of great weakness, followed shortly afterwards by a severe attack of diarrhoea, in which he rapidly lost flesh and strength, and was confined to bed for six weeks. The weakness has gradually increased, and he has latterly suffered from shortness of breath on the slightest exertion, and from swelling of the feet towards night. He has had great soreness of the mouth and tongue throughout the illness. He has had no cough. Once when suffering from piles he passed a small quantity of blood with the motions, but with that exception he has never had any hemorrhage from any source whatever. He has suffered from occasional attacks of diarrhoea for some years past. On admission, May 9th, 1896, he was emaciated and extremely anaemic, the skin being of a pale primrose tint. He had diarrhoea, with the passage of pale, loose motions. Appetite bad. Temp. 98?. Tongue pale, with transverse lines. Pulse 96, regular, small, and compressible. Pupils large.
