Sir J. Sawyer {Lancet^ Mar. 21, 1891) has employed a tincture of 

 the' fruit made with spiritus etheris, B, P., as a nervine calmative 

 and antispasmodic ; the dose is"*from 16 to 30 minims in water, but 

 the strength is not stated. We have already shown that tlie drug 

 contains saponin' and valeric acid. 



Ixora parviflora.

P. S. Mootoosawmy has sent us a sample of the bark of this tree, 

 with the remark that it is used in native medicine, mixed with a 

 decoction of ginger, for ansemic diseases ; he suspected the presence 

 of iron in it. The bark contained a little fatty matter, tannin, red 

 colouring matter and 11'5 per cent, of ash consisting of the usual 

 constituents, with only a trace of ferric oxide. The decoction of the 

 bark was of a deep red colour, which probably suggested its medicinal 

 employment. 



Note on Catechu. 



In the Library of the Botanic Garden at Oxford I recently came 

 across a book which apparently escaped the observation of the 

 indefatigable axithors of Pharmacographia, entitled '' Ehrenfridi 

 Hagendornii Medicinse D. et Pract. Gorl. Tractatus Physico- 

 Medicus de Catechu sive Terra Japonica in vulgus, sic dicta ad 

 normam Academia? Naturae -Curiosorum. Jense, 1679." This gives 

 very interesting particulars respecting the histoiy, nomenclatm'e, and 

 physical characters of Catechu. 



'^Depatria Catechu." The author writes:— *' Si Catechu agno- 

 men respicias, quod Japonica etiam indigitetar, facilis esset decisio, 

 quern agnoscat locum naialem. In ambiguo tamen usque est, an in 

 Japonica vel prseparetur vel aliunde ad Japonenses transporteter. Ex 



aliis finitimis locis in Malaccam et Sinam expoi-tari." The italics 

 are mine.
