T N. T 49 + ^ 108 -y 361 X T 107 + y 207 - y 509 X N T 1 FIRST STUDY OF STATISTICS OF PULMONARY TUBERCULOSIS U Here the numbers represent the data actually given by the Crossley Sanatorium records. Each child is entered twice, once with each parent ; x represents the number of non-tuberculous children (male or female) of non-tuberculous parents which are clearly not provided by the records, but which would be associated with this amount of tuberculous material had we reached the record of it fr...om a random sample of the general population. To explain the other unknown, y, we note that 108 and 207 are the number of non-tuberculous offspring of the tuberculous parents at the time of taking the record, y is the further number which possess the tuberculous diathesis, and might, or probably would, exhibit pulmonary tuberculosis if the family history were completed. There would of course be a similar corrective factor for the non-tuberculous parents, who might posterior to the date of the record develop tubercle.
