Special Observation of the More Important Animal Hairs 



AND Wools. 



Among these are to be classed the following sorts of animal fibers : 



1. Sheep's wool (from Ovis Aries). 



2. Goat's hair (from Capra hircus). 



3. Calf's and cow's hair (from Bos Taurus'). 



4. Angora hair (from Capra hirais ajigorensis) . 



5. Indian shawl wool, Paschima (from Capra hircus laniger). 



6. Camel's hair (from Caniehis Dromedarius and badrianus). 



7. Alpaca wool (from Aucheyiix Paco). 



8. Vicugnas wool (from Auchenia Viamna). 



9. Horse hair (from Equus caballus and other species of Equus). 



10. Rabbit hair (from Lepus Cuniculus~). 



11. Hare's hair (from Lepus timidus). 



12. Beaver hair (from Castor Fiber). 



13. Muskrat hair (from Fiber zibetlucus). 



14. Cat's hair (from Felix dottieshca). 



15. Swine bristles (from Sus scrofa and domesticd). 



I^ess important are the hairs of some common furs as they can hardly be 

 reckoned among the fibers, although they are used for the manufacture of 

 paint brushes (pencil). For this reason some illustrations with some re- 

 marks are added to the end of this article, which will be sufl&cient to give 

 an accurate conception of the subject of furs. 



Sheep's Wool. — It has been stated before that there are three kinds of 

 hairs, stichel, grannen and wool hairs. Those sorts of hairs and wools 

 which are obtained from wild or not carefully raised animals consist, 

 chiefly of two sorts, grannen and wool hairs, of which either one or the 

 other predominates ; whereas the fine sheep's wool of commerce consists 

 mainly of but one variety of hairs, either wool or grannen. Only the 

 fleece of the most common domestic sheep (Zackel sheep, German sheep, 

 Hungarian sheep, etc.) consists of an equal amount of wool and grannen
