[We have to acknowledge the kindness of the Rev. Prof. Sedgwick in 

 contributing liberally to the cost of the large number of Plates required for 

 the illustration of Mr. M'Coy's paper; as it is from the aid which he has 

 thus afforded us that we have been enabled to present our readers with so 

 valuable a contribution to our knowledge of a highly interesting and import- 

 ant subject. — Ed.]
