There are many expressions occurring in mathematics which are capable 

 of being written in more than one way ; and of these some present much 

 greater difficulties to the printer than others. This being so, your Committee 

 are of opinion that, instead of making any specific recommendations, the 

 most useful course they can take Avill be to append a table of equivalent 

 forms, specifying those which do and those which do not involve justification, 

 and also a list of mathematical signs which may fairly be expected to be 

 foxmd, in the usual sizes, ready to hand among a printer's materials. It will, 

 of course, be understood that neither one nor other of these is even nearly 

 exhaustive. But the specimens here given form the principal elements from 

 which others are formed ; and from the explanations given in the earher 

 part of the Report the intelligent reader will be able to discriminate in most 

 cases between forms difficult and forms easy to be printed. 



In recommending in this qualified way some forms of notation in pre- 

 ference to others, j^our Committee wish it to be distinctly understood that 

 they are speaking from the printing, and not from the scientific point of 

 view ; and thej' are quite aware that, even if some of the easier forms should 

 be adopted in some cases, they may stUl not be of universal application, and 

 that there may be passages, memoirs, or even whole treatises in which they 

 would be inadmissible.
