Hyperaemia as a Healing Remedy. — Bier' has drawn attention to the 

 favorable effects of chronic passive hyperaemia, produced artificially by elastic 

 bandages and by hot-air apparatuses, upon surgical suppurative and inflam- 

 matory processes. Passive hyperaemia, like active hypersemia, has a resorbent, 

 bactericidal and anodyne action and stimulates the formation of new tissue. 

 The same effects are produced by the continued employment of high degrees 

 of heat by means of Ullmann's^ hydro-thermo regulator, which was introduced 

 into veterinary surgery by Bayer^ and Eberlein^ and found by them to be of 

 value especially in chronic tendinitis, tendovaginitis, shoulder boils, exostoses, 

 thickening of the skin, articular and muscular diseases, wounds and ulcers 

 of the horse (constant, regulated heat treatment in the form of dry or moist 

 heat). Upon the basis of his experiences in the Vienna clinic, Schmidt^ has 

 formed the following conclusions concerning the value of Bier's passive hyper- 

 ffimia in veterinary medicine: The aspirator is most useful in diseases of the 

 paws of small animals (phlegmon, panaritium). The rubber tubing and the 

 elastic bandage can be used on all of the domestic animals, but the technique 

 presents numerous difficulties, which are greater in animals than in man. 

 Purulent inflammations of the articulations and tendon sheaths and phleg- 

 monous processes in the hoof are best suited to the passive hyperasmic treat- 

 ment. On account of the technical difficulties and the dangers attending the 

 treatment, however, it can only be employed in stationary clinics under con- 

 tinual control; its use in general practice and in polycUnics is precluded. 

 According to Roder^ also, the field for the use of Bier's passive hyperaemia is 

 limited; he reconunends venous stasis by means of bandages in wounds of 

 the coronet, in contused wounds and after resection of the lateral cartilage, 

 and the employment of the aspirator in shoulder boils. Kruger,* as a result
