246 Caroline Lucretia Herschel. 



I knew all that went before. Perhaps I might have done 

 so once, but my memory he used to compare with sand, in 

 which eveiything could be inscribed with ease, but as easily 

 effaced. Some time hence you will see a book* in which I 

 transcribed such lessons as my brother was obliged to give 

 me at such times when I was to set about some calculations 

 of which I knew not much about. I shall this summer 

 collect every scrap of that kind some written by my 

 brother, and some penned down as they flowed from his 

 lips, and some even incomplete, which were intended to be 

 given more correct when at leisure. I bought a very hand- 

 some portfolio for this purpose, and had my nephew's new 

 seal engraved upon the lock. 



I should not have thought of troubling my dear nephew 

 or you with looking over these fragments, but I cannot part 

 with remembrances of times long gone by, so long as life is 

 in me ; but for fear I should not have at the last moment 

 the power of burning them, I will keep them ready for being 

 sent off to Slough, for nothing of the kind shall be seen by 

 unhallowed eyes 



MISS HERSCHEL TO J. F. W. HERSCHEL. 



HANOVEII, June 4, 1831. 

 MY DEAREST NEPHEW, 



Just now I received j'ours of Ma}' 22nd, and the next 

 post will not go from here till the 7th, and I wish the wind 

 may be favourable that you may be soon made easy about 

 the 50, for which I beg you will, according to custom, give 

 the above receipt to your dear mother. And you may as 

 well add my heartfelt thanks ; for what good can it do 

 troubling her with my letters, knowing the weakness in her 

 hands will not permit her answering them
