full a diet ; the only error which appears to have been com- 

 mitted in the treatment of these animals ; this experiment 

 having, on the whole, been far more successful than those 

 carried on at Blair and Dunkeld, and giving hopes of future 

 success whenever the management shall be better understood, 

 and when, by an increase of the numbers subjected to trial, 

 occasional contingencies will be of little moment. 



It is a sufficient proof of the general healthiness of this 

 female, that, on being opened, she was found to be again 

 pregnant with twins, a male and female ; and, had not the 

 cause above suspected, or some other unknown contingency, 

 destroyed her, it is probable, that a native flock would at 

 length have been raised at Invereshie by these efforts. 



The males, which continue to thrive, passed the summer of 

 1819 in the hills, and the old one was long absent, having 

 wandered away from the others, but was recovered before the 

 winter. As these also remain in health after so long a pro- 

 bation of the oldest > there is little reason to doubt that he has 

 become fully habituated to the climate; and that the two 

 young ones are still more perfectly naturalized from the ad- 

 vantages of their birth in it. Unfortunately, no female has 

 since been procured, so that it yet remains a doubt whether 

 this experiment, so long carried on under favourable auspices, 

 will ultimately succeed so as to establish a naturalized breed. 



It is necessary here to remark, that, in the first year, the 

 original pair showed the same disease of the skin which 

 occurred in those at Blair. The wool was injured, in conse- 

 quence, in the first crop, but the animals afterwards recovered, 

 and continued clean. The feet also became tender while in 

 the lower grounds, but, as already observed, without growing 

 to the inconvenient length which they did in the animals kept 

 at Dunkeld. This disorder however subsided in the summer, 

 when they had access to the rocky hills, and showed the 

 necessity of keeping them on ground of this quality, or, where 

 that is not practicable, of paring their hoofs occasionally as a 

 substitute for the natural process of wear. The necessity of 

 this, it was already remarked, has even been observed in
