NO. 5 CURTIS BRITISH ENTOMOLOGY BLACKWELDER 25 



3. The reprints had an additional number at the bottom to indicate 

 the position of the plate in the systematic arrangement. But lo plates 

 are known without this number. 



4. Although it was not feasible to compare all the 770 plates of all 

 five sets, it was noticed that some plates in some sets had been re- 

 drawn. Redrawn copies (of a poorer workmanship) are known of 

 five plates, each in only one set. 



5. In addition to engravings and reengravings, many plates exist 

 in a poorer type of reproduction that is obviously lithography. These 

 plates do not have the impression lines of the copper engraving plates 

 and are much coarser. These are known for 267 plates but are of 

 several minor types. Straight copies of engravings by lithograph occur 

 for 119 plates. These have the date lines, but seven of them exist 

 also with the additional number at the bottom (apparently also re- 

 drawn in each case). 



6. Many lithographs occur without the date line at the bottom (155 

 plates), in some obviously deleted because remnants are still visible. 



7. A lithograph of one of the second-edition plates has been seen. 

 It has both the date and the extra number. This plate (No. 34) is 

 known also as an original engraving of the second edition and as both 

 engraving and lithograph of the first edition. 



It appears obvious from the above that in addition to the two known 

 editions, there are plate alterations, later engravings, lithographs, stone 

 alterations, and later lithographs. No definite clue has been uncovered 

 as to the age of any of these (except the two definite editions) or the 

 order in which they appeared. The lithographs might be assumed to 

 be later than 1840 and produced by someone other than Curtis, but 

 they occur in four of the five sets before me, including both of the 

 ones in numerical order, one of them in all other respects a complete 

 first edition. 



The condition of the five sets may be summarized as follows : 



U.S.N.M. All original first-edition engravings except for second- 

 edition plates 1-50 (plate 17 first edition, text second). 



U.S.D.A. All original first-edition engravings up to No. 385, with 

 many of the others being lithographs. 



A.M.N.H. Second-edition engravings complete ; first edition with 

 occasional lithographs. 



Rutgers. Engravings of both editions intermixed with occasional 

 lithographs. 



Peabody. Engravings of both editions intermixed with occasional
