and constant pressure of harness, an influence not connected with 

 the vital actions of the animal concerned, is incapable of producing 

 any similar effects. The latter is fully in accord with the extensive 

 study and negative results of the supposed inherited effects of 

 mutilations. 



Mr. Lydekker has pointed ovit the interesting opinion of 

 Darwin, that the habit, displayed by domestic horses, of clearing 

 away the snow from their pasture in winter by scraping with their 

 front hoofs, indicates that the original habitat of the species was in 

 regions where the ground is covei-ed during a portion of the year 

 with snow, so that this trait of the domestic horse, as we know 

 it, would be looked upon as vestigial. In reference to many of 

 the varieties of hair-ari-angement here given in detail, it is hardly 

 a less legitimate inference to hold that they present an epitome of 

 long-continued and oft -repeated muscular activities in the line of 

 ancestry involved, though themselves of no impoitance. 



2. On the Carpal Organ in the Female Hapaleimir griseus.

Some years ago ^ I described and figured in the male Uapalemur 

 griseus a patch of spine- like stiuctures upon the forearm close to 

 the wrist, which was associated with a gland lying beneath the 

 integiiment of " about the size and shape of an almond." I 

 figvired this patch as lying just behind the wrist and separated 

 from the callous integiiment of the palmar smface of the hand by 

 a region covered with the ordinary body- fur. Latei- ", this same 

 structure was again recognized by Mr. Bland-Sutton and figured 

 by him. Still later, I found myself able to add some further 

 details with the help of a second specimen of a male of this 

 Lemur ^. I have not been able until the pi-esent time to examine 

 a female of this species. Until this year, all the examples of this 

 species acquired by the Society appear to have been males. But 

 the death of a female example in May of this year enables me to 

 complete the examination of this novel organ, by studying its 

 characters in the female. I may remark, in the first place, that in 

 my earliest paper upon Hapalemur I was able to quote from the 

 late Prof. A. Milne- Edwards and from Dr. Jentink information 

 to the effect that the patch of spines is not present in the female, but 

 appeared to be represented by a tract of modified skin. Since 

 then the arm of this species of Lemur has been figured by
