which date Mr. Thompson wrote of it as a species; in 1850 it is 

 mentioned as " Mus Rattus ? " in 1851 as " black rat with white spot 

 on the breast." This little summary shows the readiness with w T hich 

 Mr. Thompson altered or amended his views, when he saw reason for 

 doing so. The paper on the Irish hare was published in the ' Trans- 

 actions of the Royal Irish Academy ' for 1838 ; that on Echiodon 

 Drummondii in the ' Proceedings of the Zoological Society ' for 1837; 

 and a great number of others in the ' Annals and Magazine of Natu- 

 ral History.' 



Mr. Thompson left nothing relating to insects, except a statement 

 of numbers, communicated to him by Mr. Haliday. This having 

 been prepared so long since as 1843, the editor of this volume has 

 done well in applying to Mr. Haliday for a more recent census ; and 

 that eminent entomologist has furnished a digested table of the num- 

 ber of known species brought up to the present day. This is pecu- 

 liarly valuable, both as furnishing an approximation to the real extent 

 of the Insect Fauna of Ireland, and also as exhibiting Mr. Haliday's 

 matured and most recent views on the subject of classification. We 

 have no hesitation in extracting it entire.
