Notes: | Opuscular source: Copy of letter to Director from Pearson, South African College, Cape Town 19. 05.1903. The slab of wood to which you refer is a piece of mahogany which formed part of a log cut up at the Woolwich Arsenal. It was sent there for growth, at Coopers Still, who gave it to me. The perforations are supposed to have been made by white ants. In places they contain a curious tertiary growth the nature of which was in dispute. Two suggestions were made 1. They represent an internal callus form, ed as a result of injury. 2. That they are portions of roots grown into the cavities. The latter I thought improbable. I thought it was of sufficient interest to make it worthy of a place at the museum, but kept it back in the hope that further ligh, t might be thrown upon the origin of the internal growth. I did not however succeed in finding out any more about it and quite overlooked it when I was leaving. Pearson Label source: The specimen has been submitted to Dr Scott who writes as follows.The, ingrowth shows the wood structure but much more irregular than in normal wood. There is no indication of root characters and there is every probability that the callus explanation is the right one. - ie. the internal callus was probably formed as a resu, lt of an injury |
