the great Bullc of Non-defcripts to the Examination and determination of the 

 Curious. Some Perfons, perhaps, may cbjeft to the Promifcuous AlTemblage 

 of the various Subjects here exhibited, and be ready to wifh that they had been 

 allotted in Order and Method, according to Genus and Species; and it muft 

 be confelTed, that fuch a Proceeding would have proved extremely fatisfa£lory 

 to eveny true Lover of Science. Such would have been highly pleafed to have 

 feen each Article named, and ftand in its proper Place. But however defirable 

 fuch an Attainment might have been to a few Cognofcentl, it is very certain that 

 the Majority of the World are not MethocU/is. They love Variety more than 

 Order, and would rather purchafe Twenty different Species of Cones ox turbos 

 in One Lot, than the fame Number of High Admirals or Wentletraps. Yet to 

 gratify every Palate, C?jre has been taken, as much as poffible, to keep the 

 Grand ClaJJcs^ and often the Genera together; at leaft as far as Re(pe£l to 

 Rarity^ or Beauty, would allow. And in this Difpofition, there are very few 

 Subjefts but will occur again and again ; fo that almoft every Perfon defirous of 

 becoming a Purchafer, may have an Opportunity of fupplying his Wants. 

 Whereas, in a methodical Arrangement, it muft of Neceffity have frequently 

 happened, either that a Multitude of fhe fa?ne Species muft be fold together in 

 One Lot., (which very few would chiifc to purchafe) er each Individual of that 

 Species, muft be difpofed of fingly^ or in Pairs ; which would have multiplied 

 the Number of Lots to fuch a Degree as would -extend the Sale to as many 

 Weeks^ as it confifts at prefent of Days. 



It is hoped however, that the Man oi Science will not be altogether difappdinted 

 in the prefent Arrangement of the Catalogue ; for as much Pains and Care have 

 been taken to affix the proper claffical, or generally received Names, to as many 

 Articles as the Time and Abilhies of the Compiler^'would allow ; it will be no 

 ^reat Trouble for him to caft his Eye over each Day's Sale, as it occurs, and 

 he will hardly fail to meet in one or more of them, with the Subjects he defires. 

 In Order therefore to bis more ready Underftanding the various Articles re- 

 corded in the following Catalogue, it remains only to fubjoin an Explanation <)f 

 ■the References and Abbreviations made Ufe of in it.
