+ In Series 22, the tumour was squamous cell carcinoma and alveolar-carcinoma (Jensen) 
respectively. In Series 23 they were all squamous cell carcinoma, and in Series 24 the first three 
were “ No. 27” and in the last was alveolar carcinoma (Jensen). 
These seven had all developed tumours ranging in weight from 0°3 to 
15 grammes. 
The remaining six had been inoculated with the same tumours, 
but in all of them the result of such inoculation had been completely negative.
