A few were colored at 2 guineas per fasciculus. Twelve of these were published, issued quarterly, and the complete set commands a high price to-day, being one of the most reliable Icones on this subject. The set here offered includes the first 10 fasciculi in the original parts, as issued, and costing $60.00. As each plate and part is complete in itself, not bearing necessary connection with the series, the lack of the two final parts does not affect their proportionate value.
