* I very much regret that I am unable to identify this figure : there has been a lapsus 

 calami in the MS. ; the original material is warehoused and inaccessible ; the proofs I re- 

 ceived travelling in Russia, and so had no means of verifying doubtful points. This must 

 be accepted as an excuse for any inconsistencies which may have crept into the article ; the figure 

 will be identified and discussed at a suitable occasion in a later paper. — M. B.
