X PEEFACE. 



Thus much it is necessary for me to say in answer to your 

 question. But there has been so much delay in the publi- 

 cation of the work, that I cannot let it go out without a 

 few words from me, to shew that neither Mr Crotch nor 

 Mr Janson and yourself have been in any way responsible 

 lor its late appearance. 



The work, as you are only too well aware, was only in 

 part printed when Mr Crotch left England on the first of 

 October, 1872. The manuscript of the remainder was left 

 with me to see to its completion ; but owing partly to an 

 unfortunate mistake of mine, it was mislaid and only dis- 

 covered in the autumn of 1873. Since that date I know 

 that no time has been lost on your part in correcting the 

 sheets and making the necessary verifications of references. 



Yours truly, 



HENRY BRADSHAW.
