784. Burqtje, L'ABBeF.-X. LTdentite du Poglus. [The identity of Poglus.] Le Natur-

 cies by Frere Marie-Victorin in the previous monthly issue. He closes an interesting dis- 

 cussion by the presentation of evidence that the Indians of the region (the Hurons of Lorette) 

 have actually been calling no less than three species of the Umbelliferae by the same name, 

 "Poglus," — namely, Archangelica atropurpurea, IAgusticum sp.? and Heracleum sp.? He 

 thinks that Archangelica is most likely the beneficial species for influenza. [See also Bot.

786. Clair, H. W. Scottish Chamomiles. Chem. and Druggist 91: 1512. 1919.— A 

 comparison between the dried flowers of the "single-flowered" variety of Anihemis nobilis, 

 known as Scottish chamomile, and the "double-flowered" variety of the same plant, known 

 as English chamomile. The Scottish Chamomile, formerly cultivated to a considerable extent 

 in the Deeside district of Scotland is more bitter and aromatic than the "double-flowered" 

 variety and of greater value as an internal tonic medicine. The "double-flowered" variety 

 was not obtained by ordinary cultivation from the "single-flowered" type, but by collecting 

 seed from "sport" plants, and by a careful process of selection from these deviating forms 

 a strain which retained the habit of producing "double flowers" was obtained. The Scottish 

 chamomile is used but slightly outside of Scotland. — E. N. Galhcrcoal.

 The cultivation and propagation is very easy and inexpensive. The cuttings of old plants 

 are set in rows about 0.5 m. apart, when in due time a short stem and rosettes of leaves will 

 be produced, and, after the rains, a flowering stem, which divides into two or more branches,
