204 HERSCHEL AND HIS WORK

Herschel's friendship with Dr. Wilson. 1 tlu Pro- 

 fessor of Astronomy in Glasgow University, was 

 probably the reason of repeated visits paid by liim 

 to Scotland. Of the first of these visits no notice

 known visit was made eighteen years after, is bririly 

 referred to by his sister, and is confounded by liis 

 biographers with that of 1792. It took place in 1810. 

 A third visit, obscurely hinted at by his sister, took 

 place the following year. In a paper read to the 

 Royal Society in 1812, he mentions an observation

 records another which he made at Alnwick on his 

 way south, some weeks later. That Glasgow may 

 have been to Herschel a place of summer pilgrim IL:< 

 more frequently than on these three visits seems not 

 improbable. His friendship with the Wilsons and 

 their families, like that with Dr. Watson, was close and 

 long continued, the friendship of worthy men, holding 

 each other in the highest esteem. As he visited Dr. 

 Watson at Bath and Dawlish, so he appears to have 

 visited the Wilsons at Glasgow. At any rate we
