cxviii Proceedings of the Asiatic Society. QOct. 1844. 



They are sold as medicine, at 6 rupees per seer. It will be seen that amongst those 

 I have obtained, some have parts of the matrix adhering to them, others have buds or 

 gemmules, like the corallines, at their base ; one has perhaps an incipient ramification 

 like Cyathophyllum ; another traces of a serpula adhering to it, and another the trace of 

 a small oyster or other shell-fish ; internally no trace of organisation is seen. Upon dis- 

 secting one of these in dilute muriatic acid, I find that it almost entirely dissolves, the 

 solution being pure carbonate of lime with traces of iron, as usual in the grey coloured 

 marbles. A small yellow, green residuum, in light flakey grains remains at the bottom 

 of (he glass, and when this was examined by the usual tests, it was found to be iron with 

 trace of sulphur. Nothing of animal or vegetable matter, nor any siliceous spines as in 

 the Echinidse are traceable. We may I think call this fossil, (provisionally) Loheido- 

 lite, which does not pronounce upon its nature.
