432 SCIENTIFIC NOTES. 



From Turkey there were several exhibitors, who showed a variety of 

 skins indigenous to the country, consisting of marten, red fox, lynx, 

 wolf, jackall, cat, hare, and badger. The skins most worthy of notice 

 were the marten and hare. The hare skins were very large, the fur of 

 these being much valued for felting and hat-making.

Fir-Wood Paper. — The Rosendahl Manufacturing Company of 

 Gottenburg makes yearly about 1,000,000 lbs. of paper from fir-wood. 

 The wood is ground at a mill at the Trollhattan waterfall, using about 

 180 horse-power, and occupying twelve persons daily. The Jury made 

 honourable mention of this paper in 1862. 



Aliantus Silk. — The new Chinese silk-moth Saturnia, or Bombyx 

 Cynthia, has been introduced into Canada, where the Aliantus glandulosa, 

 on which it feeds, is quite hardy. Professor Lawson states that the 

 chief obstacle in manufacturing this silk — the difficulty of unwinding 

 or cording the cocoons — will no doubt be overcome by the method of 

 soaking them in caustic potash, which has been found to answer 

 so well in the case of the much larger parchment-like cocoons of the 

 Canadian Cecropia. The potash disintegrates the parchment-like mem- 

 brane into its constituent thread, by dissolving the adhesive substance 

 which "lues them together.
