Mann. E. TY. concludes that it is possible to chemically standardize 
stroplianthus and its preparations, but that the standardization can 
only have a real value when the botanical character of the seeds is 
fullv established, and. failing this, the activitv of the drug can onlv 
be tested by jffiysiological experiments. — Ibid., v. 23. p. 93: also 
Year Book of Pharmacy. 1906. p. 249. (For discussion, see p. 117.) 
lYuney. in discussing a paper by Mann, asserted that he had taken

Ball. A. TY. announces that the African Lakes Corporation has 
arranged to have the seeds of Stroplianthus hornbe which they export

The Ph. Brit. Committee of Reference in Pharmacy report on 
strophanthus says the reaction with sulphuric acid has not proved 
of great value, as seeds from the same pod have given a green and
