Abstract
THEreport by a committee of pathologists of three nations which has been inquiring into swollen shoot disease of cacao (His Majesty's Stationery Office, Colonial No. 236) contains matter of interest beyond the field of inquiry. Pathologists in the past have often been inclined to consider infection in a biological vacuum. The disease organism (assisted in the case of viruses by a vector) was regarded as an agent of destruction subject to no external conditions except those which might be imposed by pathologists.
