    Association of Rheumatism in Husband and Wife. 1910—1912 Data (Table V). 1910—1912 Data (Table By Contingency: -147 -159 Tetrachoric r: -137 ‘148 Mean of four: ‘IfS. To further test the material we divide it into two nearly equal parts corresponding nearly to 1910—1911 and 1911—1912 data. We reached the following fourfold tables : Table Z*'®. Mother Mother 1910—1911 Rh. + Rh. F. Not Rh. Totals 1911—1912 Rh. + Rh. F. Not Rh. Totals Rh. + Rh. F. 36 97 133 Rh. + Rh.

It will be seen that tetrachoric r is substantially the same for the two halves of our material. On the other hand the relatively few data for 1913 appear to indicate an increase in the mother-father correlation, but before we can assert that this is real it is better to wait for more complete material. It would appear that the record in the case of husband and wife has been far more steady than in the case of children. There seems in the latter case to have been a substantial change in the nature of the diagnosis during the three years under consideration. The material so far discussed suggests the inclusion in the “ rheumatic ” groups of a far larger number of children with “ growing pains.” During the progress of this paper, however. Dr Williams continued her observa- tions and now recorded in each case the grounds of her diagnosis. We were thus placed in a position to analyse more closely what might possibly be the sources of the change. An attempt was made to get closer to the source of the change observed in values in the parental correlation of rheumatism by an analysis of the various elements of this fuller diagnosis of “ rheumatism ” or “ ? rheumatism ” in the children examined. Cases in which the grounds of the diagnosis were not stated—relatively few in number—were at first omitted. Tables AA and BB give the classified material. The following classes were used by Dr Williams: ? Rheumatism a = Doubtful growing pains b = Heart c = Choreic movements d = Nervousness e. = Abdominal pain f = “JMoithers” at night or Night Terrors y = Sore throats Rheumatism A = Growing pains B — Heart C = Chorea 1) = Nervousness E = Abdominal pain A* = “ Moithers ” at night or Night Terrors G = Sore throats II = Nodules J = Purpura
