CHAP. X.] SCIENTIFIC WORK. 291 



To H. R DKOOP, Esq. 



129 Union Street, 

 Aberdeen, 14th November 1857. ; 



I am very busy with Saturn on the top of my regular 

 work. He is all remodelled and recast, but I have more 

 to do to him yet, for I wish to redeem the character 

 of mathematicians, and make it intelligible. I have a 

 large advanced class for Newton, physical astronomy, the 

 electric sciences, and high optics. "What is your depart- 

 ment by the way ? 



I have also a mechanics' class in the evening, once a 

 week, on mechanical principles, such as doctrine of lever 

 work done by machines, etc. So I have 15 hours a week, 

 which is a deal of talking straight forward. 



I am getting several tops (like the one I had at Cam- 

 bridge) made here for various parties who teach rigid 

 dynamics. 



To C. J. MONRO, Esq. 



127 Union Street, 

 Aberdeen, 26th November 1857. 



The enclosed letters came from Mrs. Pomeroy to me. 

 I think they are, one of them at least, yours. I doubt of 

 the smaller one, but you will know. They seem dropping 

 in still on poor Mrs. Pomeroy. Even ordinary returned 

 letters are strange things to read again, as if you had been 

 talking on when everybody had gone away. 



I got your letter of the 6th. I have been grinding so 

 hard ever since I came here that I left many letters un- 

 answered. When I have time I shall write to you, and 

 meanwhile only thank you for your letter. 



I am at full college work again. A small class with a 

 bad name for stupidity, so there was the more field for 

 exciting them to more activity. So I have got into regular 

 ways, and have every man viva voce'd once a week, and the 

 whole class examined in writing on Tuesdays, and roundly and 

 sharply abused on Wednesday morning ; and lots of exer- 

 cises which I find it advantageous to brew myself overnight.
