Sic oportet ad librum, presertim miscellanei generis, legendum accedere lectorem, at solet ad conviviam convira
civilis. Convivator annititur omnibus satisfacere , et tamen si quid apponitur, quod hujus aut illius palato non
respondeat, et hie et ille nrbane dissimulant, et alia fercula probant, ne quid coatristent convivatorem,

Erasmus.
A reader should sit down to a book, especially of the miscellaneous kind, as a well-behaved visitor does to a ban-
quet. The master of the feast exerts híunself to satisfy his guests ; but if, after all his care and pains, something should
appear on the table that does not suit this or that person's taste, they politely pass it over without notice, and commend
other disbes, that they may not distress a kind host.
