PREFACE. 



the second volume of the Catalogue of the Collection of Books, 

 Maps, &c., in the Natural History branch of the Museum, brings the 

 series of entries under authors' names down to the end of the letter "K," thus 

 completing the first half of the entire work. 



Thanks for assistance in its production are due to the coadjutors already 

 mentioned in the preface and introduction to the first volume.
