9th. All hair is not polaric. 



10th. 'I'here are various degrees of the felting property in wool, which may 

 be detern:iined by the aid of the microscope, as they depend upon the number, 

 shape and adherence of the scales. 



11th. The softness of any woolly fabric, is in exact proportion to the ductiliit/ 

 and elasticity of the filaments of which it is composed ; and the ductility and 

 elasticity of the fibre can be accurately determined by the trichometer. 



12th. The method in common use of determining the diameter of any filament 

 that is not cylindrical is inaccurate, for every filament that is not cylindrical 

 has two diameters, which cannot be accurately determined, except by using 

 transverse sections. 



13th, That in all cases of doubt or difliculty, whether a filament is or is not a 

 true hair, it can be determined with the trichometer. 



1 1th. The button of the pile of the head of man changes its shape and color in 

 diseases of the hair, and in diseases of the skin that affect the hair. 



15th. The buttons of the pile of the head of lunatics differ from those of the 

 sane. 



16th. There is no difference between the wool found upon the head of a pure 

 negro, and that found upon the back of a woolly sheep, except in the degree of the 

 felting power possessed by them. 



Dr. Morton in remarking upon the cranium of the Dijak deposited 

 by him this evening, referred to the great difficulty in obtaining these 

 crania, and stated that Mr. Wra. Gliddon, from whom he had derived 

 the present specimen, had been unable, during many years residence 

 in Borneo, to induce the natives to part with any of their trophy skulls 

 upon any consideration. This had been carried off by a Dutch officer 

 on a warlike expedition. 



Dr. Morton announced the decease of Mr. John J. Audubon, a member 

 of this Society; and after some appropriate observations upon the life 

 and chE?racter of this distinguished zoologist, moved the following 

 Resolutions, which were unanimously adopted : 



Resolved, That this Society has heard with profound regret of the 

 death of their esteemed and venerable colleague, John James Audubon, 

 at his residence near the city of New York, on the 27th ultimo. 



Resolved, That by the demise of this truly great man, Science has 

 lost one of her most zealous and gifted disciples, and the Arts, a master 

 in the branch which he cultivated. 



Resolved. That we recognise in Mr. Audubon a man who has happily 

 lived to fulfil his destiny as an explorer of the great field of American 

 Zoology, while the splendid volumes which are the fruit of his labors, 

 will diffuse the knowledge and the love of science to the latest genera- 

 tions. 



Resolved, That a copy of these Resolutions, signed by the officers, 

 together with the sympathy of the members of this Society, be respect- 

 fully tendered to the family of Mr. Audubon. 



On leave granted, the Committee, to whom was referred the paper
