History.—Cannabis was well known to the ancients, but they 
did not seem to be aware of its narcotic properties. Herodotus 
designates it under Kawafis nuegos, and states that the Thracians 
made a kind of cloth from it. The seeds were also thrown upon 
‘red-hot stones, and the perfumed vapour obtained in this man- 
“ner used for a bath, which excited cries of exultation. Dr. 
os Royle considers it to be the same as the Nepenthes of Homer, 
: Spee oe of ass <i by Helen to Telemachus in 
Fi 1. Theale lat, 2. The female. 3. Calyx and stamens of male plant. 
4. A separate nther. 5. Female flower.” 6. The seed.
