The Chairman said that Eucalyptus risdoni was ahnost in- 

 variably found growing on soils derived from the mudstone- 

 formation, an upper member of the marine permo-carboniferous. 

 series, and the geological character of hills at a considerable 

 distance might often be recognised by the bluish tint of the^ 

 foliage of the trees growing on them. The relations of trees 

 and plants to the soils on which they grew was one of the most 

 interesting studies in botany. 



3. Notes on the Genus Lissotes, with Descriptions of New- 

 Species. By Arthur M. Lea. F.E.S., Government Entomolo-

 by the exhibition of a fine collection of specimens. 



4. Skin Diseases treated by Blood Vaccine. Bv E. \V. T. 

 Ireland, M.B.. CM. 



The author says that the paper was intended' to emphasise a 

 possibility long recognised by the medical profession that skin 

 diseases might originate in internal conditions, and that they 

 might be successfully treated by the administration of vaccines 

 prepared from cultures of each particular patient's blood. 



Dr. Purdy said that he was inclined to think that the results 

 which Dr. Ireland had claimed were largely due to psychical 

 causes. In recent experiments tried in England remarkable 

 results had been obtained by the subcutaneous injection of 

 sterilised water, and it was no doubt due to the influence of the 

 patient's mmd over his body, andl the influence of the physician 

 over the patient's mind. If Dr. Ireland's results were borne out 

 by further investigation, he had undoubtedly made a discovery, 

 which would place him on a level with such men as Pasteur 

 and Koch, but if the same results were produced by simple 

 injections of water it would show that the phenomena were 

 simply psychical. He gave instances of the remarkable results 

 produced b}^ suggestion. 



Mr. A. J. Taylor said there was no dou»l)t that suggestion 

 formed the main feature in the Christian science treatment.
