    SUMMARY OF CONCLUSIONS. 1. Stammering is not primarily a disorder of the central nervous system. Nor is it an isolated, freak or just functional affair, but is always at the start a symptom and part of a widespread or systemic condition. 2. This general condition is a phase of hyperthymism, closely allied to or part of that known as lymphatism. The clinical coincidence herewith of the facts regarding stammerers is both proof and control of the correctness of the explanation offered. 3. There is regularly some block in the thymic area, usually attributable to thymic enlargement or persistence. 4. The morbid influence thus exerted and constituting the immediate cause of the stammer may provisionally be classed as an inhibitory reflex, systemic or other influences acting as accessories. 5. Circulatory troubles, present in at least half the cases, play a considerable though auxiliary role. Like¬ wise any interference with free naso-pharyngeal respira¬ tion, coryza, laryngitis, etc. 6. Developmental bone defects, largely of rachitic type, are common in stammerers. Some degree of muscular hypotony is the rule in youthful sufferers, involving especially the trunk muscles. Excessive eating is a feature in nearly all cases. The cases presented indicate also a moderate overgrowth in height. 7. Enlargement of the thyroid is more common in girls, while that of thymus is more common in boys. 8. The relative immunity of females to stammering is due to, a, the lesser frequency of thymo-lymphatism in girls, b, the costal type of respiration in females.
