Note 1990 — LETTER XXXV. (continued 3)
Reading edition
Plate XXVII. Fig. 58. M. Savigny affirms that these insects cannot have, and really have not, but one pair to each segment; only that the segments are alternately membranous and shelly, and that the former are concealed under the latter (Anim. sans Vertebr. I. i. 44.): but, pace tanti viri, I cannot discover that any suture separates these portions from each other: so that, admitting his theory, they must be regarded as two segments soldered together.
