to hold the said white bear while fishing or washing himself in the river 

 Thames. In 1255 they were directed to build a house in the Tower for 

 an elephant, which had been presented to the King, by Louis, King of 

 France." In 1657 there were six lions in the Tower; in 1708, eleven 

 lions, two leopards or tigers (Strype, the historian, it seems, knew not 

 which), three eagles, two owls, two cats of the mountain, and a jackall. 

 The collection varied till 1822, when Mr. Alfred Cops, the present keeper, 

 succeeded to the office, and greatly increased it, as the sixty animals 

 described in the present work fully prove. 



The whole of the drawings of these animals are from the pencil of that 

 eminent artist, to whom this Magazine is so much indebted, Mr. William 

 Harvey, " who, in seizing faithful and characteristic portraits of animals 

 in restless and almost incessant motion, has succeeded in overcoming diffi- 

 culties which can only be appreciated by those who have attempted similar 

 delineations." The literary department has been superintended by J. T. 

 Bennet, Esq. F.L.S., a scientific naturalist, and an active member of the 

 Zoological Society, assisted by various eminent zoologists. 



The engravings, we have already said, are equal to any thing that has 

 ever been done ; and we hope their appearance, as well as those in our ow-n 

 and similar works, will lead publishers to adopt this mode of illustration 

 much more generally than they have hitherto done. The EncyclopcEdia 

 Metropolitana^ for instance, now in the course of publication, illustrated by 

 elaborate, highly finished copperplate engravings, would have been a much 

 more useful book if the engravings had been on wood, and printed along 

 with the text ; and it might also have been sold at a less price : in short, 

 we see little use for copperplate engravings, except where they are to be 

 coloured after nature.

The first memoir is on the Metamorphoses of the Crustacea, and on 

 Zoea, exposing their singular structure, and demonstrating that they are 

 not, as has been supposed, a peculiar genus, but the larva of Crustacea. 

 Dr. Leach, one of the chief investigators of the Crustacea, has assigned it 

 {Enci/c. Brit., art. Crustacea) as one of their principal characters, that they 

 undergo no metamorphoses; but Mr. Thompson having, in 1822, met with 

 the genus Zoea (ord. Crustacea) in theTiarbour of Cork, kept some of them, 

 and had the satisfaction of witnessing the metamorphoses first described by 

 the Dutch naturalist. Slabber. The second memoir is on the genus 

 Mysis, or Opossum Shrimp. The author is evidently an ardent and 

 scientific student : he has already added several new facts to science, and 

 will, we have no doubt, increase their number in the course of his pur- 

 suits.

" The reputation of the former series of this work renders it necessary 

 only to state that the execution ojf the new series will be equally beautiful. 

 Each number will contain five coloured plates, resembling drawings, with 

 their descriptions." {Lit. Gaz., Feb. 7. 1829.)
