X PREFACE. 



speak here of the utility of such Registers, as this 

 point will be found amply discussed in the Introduc- 

 tion above alluded to. 



In conclusion, it may be added, that though all 

 the "Observations" which form the main part of 

 this work are original, yet from the circumstance of 

 their having been mostly made many years back, it has 

 happened that similar ones, in some instances, have 

 been since made by other persons. Where this has 

 been the case, the observation has still been admit- 

 ted ; and a reference has been given in a note to 

 those works (so far as they are known to the author) 

 in whicn the observation already occurs, or in which 

 there is anything connected with the particular fact 

 to which it relates. The author has also transferred 

 to the notes all the scientific names of the animals 

 spoken of, (except where they have no English one 

 generally received) ; as well as any matter of a more 

 strictly scientific nature, which it was thought de- 

 sirable to introduce, in further illustration of the 

 particular subject under notice, but which was con- 

 sidered as not likely to be interesting to the general 

 reader. 



It was intended that this work, which was an- 

 nounced as in preparation a considerable time back, 

 should have appeared before now, but the author 

 found so much more labour in the arrangement of 

 the Calendar than he at first anticipated, that his 

 professional duties did not allow him the requisite 

 leisure for getting the whole ready for publication 

 sooner.
