Mr. Donnelly also protests that his records of his excavations “were exceptionally complete,” and that he “took daily notes and sketches of all features and finds with measurements.” I must mention these facts, as, in the book, I say that Mr. Donnelly “kept no minute and hourly dated log book of his explorations, with full details as to the precise positions of the objects discovered.”

If in any respect I have misconceived the facts and arguments, I trust that the fault will be ascribed to nothing worse than human fallibility.

I have to thank Mr. Donnelly for permission

to photograph some objects from Dumbuck and for much information.

To Dr. Munro, apart from his most valuable books of crannog lore, I owe his kind attention to my private inquiries, and hope that I successfully represent his position and arguments. It is quite undeniable that the disputed objects are most anomalous as far as our present knowledge goes, and I do not think that science can give more than all I plead for, an open verdict. Dr. Ricardo Severe generously permitted me to reproduce a few (by no means the most singular) of his designs and photographs of the disputed Portuguese objects. A serious illness has prevented him from making a visit recently to the scene of the discoveries (see his paper in Portugalia, vol. ii., part 1). I trust that Dr. de Vasconcellos, from whom I have not yet heard, will pardon the reproduction of three or four figures from his Religiões, an important work on prehistoric Portugal.

To Dr. Joseph Anderson, of the National Museum, I owe much gratitude for information, and for his great kindness in superintending the photographing of some objects now in that Museum.

Dr. David Murray obliged me by much information as to the early navigation of the Clyde,

and the alterations made in the bed of the river. To Mr. David Boyle, Ontario, I owe the knowledge of Red Indian magic stones parallel to the perforated and inscribed stone from Tappock.

As I have quoted from Dr. Munro the humorous tale of the palaeolithic designs which deceived M. Lartet and Mr. Christie, I ought to observe that, in L’Anthropologie, August, 1905, a reviewer of Dr. Munro’s book, Prof. Boule, expresses some doubt as to the authenticity of the historiette.
