The staggering movements were not however always present. Johnstone has described a fungus, apparently nearly related to the preceding; it occurred in plaice kept in the hatchery pond on the Isle of Man. Infected fish swam about languidly, but showed neither evidence of giddiness, nor lack of co-ordination in their movements. Externally the spotted haddock is often firm and hard: but when it is split for curing, the flesh emits an unpleasant smell, which is to some extent reminiscent of creasote. The smell may not be noticed in the fresh condition, but it becomes evident after the fish has been smoked. If the cured fish are kept hanging a day after smoking, before they are ^ Faroe f^lugga Lt. ^'Shetland 0^° Orkney. Hoc kail Fig. 2. packed, the odour seems to be accentuated. The smell may be detected in the smoke kiln. 8uch fish are said to have a sour taste: the flesh when smoked has sometimes a greenish tint and, when observed, they are rejected. The main weight of the evidence at present available points to the conclusion that the spotted haddocks are not found among the North Sea fish landed at Aberdeen, although in the opinion of some observers they are so. There is however general agreement that they occur fre- quently among the haddocks caught at Shetland, both line- and trawl- caught. The West of Orkney also is given as a locahty of origin. Dift'er- ence of opinion exists as to whether they come from the West of Scotland. Infected fish, both large and small, are found all the year round, but more commonly in warm weather. Ann.
