    developed. The groups correspond with the position where the cutaneous branches pierce the fascia or are distributed in the skin, and there is often tenderness, as Parrot pointed out, m these positions. , In an intercostal herpes, one group is seated near the spine, another in the axillary region, and a third close to the med.an line anteriorly, but sometimes a group fails to be developed or remains papular, or there may be more than one group in each region, but the half-girdle is seldom continuous. The vesicles vary in size from a pin's head to a pea, or larger when confluent, and m number from half-a-dozen to a score in each group. The contents are at first clear but soon become turbid, and in a simple case soon dry up into scabs, which fall off in a few days, leaving red marks which take somewhat longer to disappear. The whole process up to the falling off of the scabs lasts from ten days to three weeks. Variations.—H. zoster is by no means confined to the trunk, as Willan thought, calling the eruption when occurring elsewhere H. Phlyctenodes, though the nerves of the trunk, especially on the right side, are more often affected than those of all the other regions added together. It may attack the domain of almost any cutaneous nerve, though it has preferences. On the head, branches of the fifth are frequently affected, especially the supra- orbital, and in this case the eruption extends on to the scalp, as it also does when the occipital nerve is attacked. A more or less severe conjunctivitis is apt to accompany herpes of the ophthalmic division of the fifth, especially, but not exclusively, when the nasal branch is affected. Severe scarring is also a frequent sequel to this form of herpes. When the second branch of the fifth is involved, patches of herpes may also develop on the buccal mucosa, palate and tonsil on the same side, and Stephen Mackenzie once found at a post-mortem, herpes in the pharynx and oesophagus. The teeth on the affected side sometimes fall out, and even necrosis followed in Paget's case* The nerves dis- tributed to the neck, arm less frequently, the forearm and hand, the buttock, genitals, thigh, and other regions are from time to time affected, and sometimes it may be two neighbouring regions, such as the neck and arm, trunk and arm, genitals and thigh, etc. It is rare below the knee and very seldom on the foot, except
