Mathematical MSS. The MSS. of the late Mr. Temperley, tutor of 

 Queens' College, Cambridge, Fourth Wrangler and second Smith's Prize- 

 man, 1871 ; consisting of notes on Bookwork, some Eouth MSS., and 

 some printed problem papers with MS. solutions, together with papers 

 containing about 5000 problems with solutions to 3000, extending 

 over almost the whole range of Pure and Applied Mathematics. In 

 all 5 Stone's boxes, 18 Spring Covers, 10 Note Books, and 7 Parcels. 

 £15. 



Such a collection as the above, embracing the MS. material of one who was long 

 engaged in teaching Mathematics at Cambridge, has probably never before been 

 offered for sale, and the large number of Problems with Solutions (3000) must be of 

 great value to any Mathematical professor or teacher.
