IREDALE : BOOK NOTES. 85 



peculiar. I have not yet collated it page by page, hut I think 

 that it must have been published in livraisons, and that these 

 appeared after the Paris print, probably without any addition. 

 The date 1837 on the title-page of the first volume may be the 

 date of the first livraison, as the date 1839 on the title-page of the 

 third is certainly not the date of the completion of that volume. 

 Towards the end Eeeve's " Conchologica Systematica " and his 

 " Conchologica Iconica " are quoted, the former being first published 

 in 1842, the latter in 18-13. Apparently the project was not a success, 

 since this third volume completes the work, a general index to the 

 three volumes being given, yet the whole of the Mollusca have not 

 been treated of. Upon examination I find that these three volumes 

 may coincide with the nine volumes of the second edition, the ninth 

 volume being published in November, 1843, and its end agreeing with 

 the completion of the third. The reconciliation is more difficult than 

 it appears at first because the volumes of the second edition appeared 

 somewhat erratically. The dates of publication of the first two 

 editions appear in Sherborn's Bibliography to the second part of 

 his Index Animalium, but I here reproduce the dates of acknowledg- 

 ment from the Bibl. France : —

The inclusion of the matter for the third volume of the second 

 edition, which did not appear until 1840 in the first volume of 

 the third edition, which bears the date 1837, is just as puzzling as 

 the date of the third volume, 1839, with contents dating to 1843. 



'■' Lessons on Shells." 



A little book was published with the title " Lessons on Shells, as 

 given to children between the ages of eight and ten, in a Pestalozzian 

 School, at Cheam, Surrey ", by the author of " Lessons on Objects, 

 illustrated by Ten Plates, drawn from Nature ", in 1832. The Preface 

 is signed by " C. Mayo, Cheam, June 15, 1832 ". Among the list 

 of books consulted appears " The Conchologist's Companion ". The 

 lessons are really good and the children must have been precocious 

 who digested the matter provided, if of the ages stated. The plates 

 are quite well drawn, and on this account are quoted by Deshayes 

 in Lamarck's Histoire. On discovering this I prepared this note as
