One word may be added as to the treatment of shock when severe. Quiet in the supine position, and the administration of a small amount of stimulant, was usually all that was required. Hypodermic injections of strychnine sulph. grs. 1/30 to 1/10 were useful, and in some severe cases, especially where operations were needed, saline infusions with a small amount of stimulant were made into the veins, either at the elbow, or in amputation cases into one of the large veins exposed. The treatment of haemorrhage is dealt with in Chapter IV. The after treatment of simple wounds needs little comment, but bearing in mind what has been said as to the definite healing of the internal portion of the tracks, it will be obvious that in parts such as the thigh or calf, care was needed as to not commencing active work at too early a date. On the other hand, a too long period of absolute rest is also to be deprecated. The best results were obtained by careful movement and massage, commenced after the first week or ten days, according to the appearance presented by the external wound, followed by a gradual resumption of active movement. It was a striking fact that some of the patients suffering from such wounds took longer to become apparently well than many of those who had suffered visceral injuries.

CHAPTER IV INJURIES TO THE BLOOD VESSELS The small calibre of the modern bullet, and its tendency to take a direct course, naturally favour the occurrence of more or less uncomplicated wounds of the large vascular trunks, and both the nature of these wounds and the results which follow them are in some respects most characteristic. NATURE OF THE LESIONS 1. _Contusion or laceration without perforation._--(_a_)The vessel may be struck laterally, the injured portion then forming a part of the bounding wall of the wound track, or (_b_) one or more layers of the vessel wall may be destroyed over a limited area. Given primary union, these conditions are only of importance in so far as subsequent contraction of the lumen of the vessel may result from implication in the neighbouring cicatrix. One of the most striking features of the wounds as a whole was seen in the hair-breadth escapes of the large limb vessels with no subsequent ill effects, and such injuries were seen in every situation.
