as those sciences are cultivated." — 

 P. 87.

" The incomparable (dissections 

 of) Savigny."— P. 87. 



" The exquisite and elaborate 

 work of Poli on the Comparative 

 Anatomy of the Mollusca, is alone 

 sufficient to immortalize a name; 

 and this unrivalled publication led 

 the way to the valuable Memoirs by 

 Cuvier on the same class." — P. 89. 



2. " Mr. Swainson's facts are not 

 accurate, and his bibliographic know- 

 ledge incorrect." — (Followed by the 

 pompous announcement of two little 

 known works of Merrems, and one 

 by Caius, in 1570, upon Breeds of 

 Dogs.) 



3. Relations of analogy — " by 

 which it appears the author intends 

 resemblance ; though we need scarcely 

 stop to say these are matters totally 

 distinct." 



2. Instead of two or three, the 

 writer, had he known of them, could 

 have enumerated near 200 books, 

 which, in the "Sketch" of Zoology, 

 Mr. Swainson must have purposely 

 omitted, for they would have filled 

 the volume. 



3. " Relations or resemblances, in 

 the ordinary acceptation of the 

 words, have long been considered as 

 of two kinds, expressed by the terms 

 analogy and affinity.'' — P. 182. 



4. " Relations of analogy have 

 chiefly been sought out by the exer- 

 tions of himself and his brethren, 

 and behold the specimens which he 

 produces of the value of their la- 

 bours. 



' The eagle he is lord above, 



The lion lord below,' &c. 

 ' The zebra and the tiger,' &c. 

 " The fact, indeed, of the resem- 

 blance in all these cases, is perfectly 

 undeniable ; but no (collateral) proofs 

 are to be drawn from them !" 



4. These are popular illustrations 

 of what the writer actually admits to 

 be resemblances — that is, analogies. 

 The " specimens " of scientific ana- 

 logy constantly appealed to, are those 

 substantiated by Mr. MacLeay, in 

 the circles of Lamellicorn insects, and 

 by Mr. Swainson, in the Northern 

 Zoology : of both which " speci- 

 mens " the writer is truly or wilfully 

 ignorant. 



5. " On another point we can be 

 more positive. — We had the plea- 

 sure, this morning, of seeing a consi- 

 derable number of the Sloanean 

 insects ; which we have Mr. Swain- 

 son's authority for asserting, cannot 

 now, by any possibility, be in ex- 

 istence ! To be as particular as 



5. A quibble. The author's ob- 

 vious meaning is, that the insects 

 could not now exist in an entire, or 

 even a tolerably perfect state ; and 

 this the writer confirms. Having 

 seen these relics, he knows that they 

 are all " ghosts" — broken wings, " a 

 aood deal faded in colour," as he
