I must state, however, in extenuation that I etched the sur- 

 face of my section with hydrochloric acid, and the results led 

 me to believe in the presence of carbonate of lime. Within 

 the last few days I have applied the same acid to the reverse 

 of a polished specimen in the British Museum, and found 

 effervescence not to be confined to the spicular parts. I 

 cannot but believe that I examined an imperfectly silicified 

 portion of the infilling material. That some specimens have 

 a perfectly siliceous infilling I am now well aware. With 

 regard to the replacement of siliceous lithistid spicules by 

 carbonate of lime I have had no doubt for a long time, and 

 the careful reasoning of my friend Prof. Sollas convinced me. 

 Moreover, lately Prof. Hodgkinson has given me the chemical 

 proofs of the possibility of the replacement. Nevertheless, 

 being still satisfied regarding the nature of the perforating 

 organism, I cannot give my adhesion either to Dr. Rauff's 

 or Dr. Hinde's condemnation of the hypothesis of the exist- 

 ence of originally calcareous lithistids, especially when it is 

 quite possible that the siliceous spicules of Hindia discovered 

 by Dr. Hinde may be silicifications of originally calcareous 

 spicules. Whenever the evidence to the contrary satisfies me, 

 I shall at once acknowledge my error.
