The existence of two fragmentary .sets in the original wrapjiers 

 has become known to us : one at tiic Academy of Sciences, I'hila- 

 delphia, U.S.A., for details concerning which wo are very greatly 

 iiidf])ted to Mr. E. J. Nolan, of that institution ; the other sot is in 

 the lil»rury of the "• Hull Literary and Philosophical Society," and 

 we have to tliank Mr. T. Shoppard, of the Hull Museum, for 

 assisting us to obtain delaile<l information about, it. Our otlier 

 sources of information are set out in tlie t^ible that foHows. 



Some few blanks still remain to ho tillel, despite a patient search 

 through contenii)orary litcr.itiirr.
