 written to Washington for them, but, like all I write for, nothing comes. 



After that his only work ou plates was retouchiug and burnishing. 

 That these plates were not all that he made for the cotton and orange 

 series is evident from various allusions to "etching" in tbe journal 

 for the year 1857, while in Mississippi, one entry being "etching cotton 

 blight."' 



The above extracts show the design originally of a work on cotton 

 and orange insects, in which the insects of different orders, on the same 

 plate, were grouped together indiscriminatelj' . Other plates were pre- 

 pared in accordance with this purely economic scheme of arrangement, 

 and some of these, on which some one order of insects predominated, 

 were afterwards incorporated in the final work, the inappropriate figures 

 being burnished out and other insects substituted. Some of these plates 

 may be known in the "illustrations" by having a flower or part of a 

 plant in tbe center, around which the figures are arranged. Other 

 plates, made in accordance with the purely economic scheme, were sup- 

 pressed altogether. * 



I notice in the private journal for 1855, at which time Mr. Glover was 

 in Florida and the Carolinas, under date of June 10, this entry : " Draw- 

 ing and sketching — improved method of coloring — pressed insects." A 

 note-book of this year's work was filled with lepidopter a drawn (?) after 

 this method, the process for which, when Mr, Glover first showed me 

 the series, he described as follows: The wings were carefully detached 

 and laid in proper position, after which very thin paper, coated with 

 some adhesive substance, probably mucilage, was pressed upon them ; 

 after going over every portion carefully, with gentle pressure, to insure 

 complete contact, the wings were removed, the scales only remaining, 

 by which means a very perfect fac simile of the markings was obtained. 

 The fragment of paper was then carefully trimmed to exact form of 

 wing, glued upon the pages of the note-book, body, etc., slietclied in, and 

 the figure was complete. I think Mr. Glover only employed the process 

 (in part) during one or two seasons, as he explained to me that its chief 

 use was to save time in making drawings, or the annoyance of carrying 

 around a collection of the iireserved insects. 



After leaving the United States Patent Ofiice, in the winter or early 

 spring ot 1859, Mr. Glover gave himself heart and soul to his final con- 

 ception of an illustrated work on entomology, for he had realized the 



* The writer has a number of proofs of these, as well as impressions of two or three 

 plates as they appeared before alteration and the addition of new figures. (S^e plate
