VIII Bashford Dean Memorial Volume 



Most of the illustrations for the article on the Structure of Dinichthys were prepared 

 by the author, Dr. Anatol Heintz;, Curator of the Paleontological Museum, Oslo, Norway. 

 Dr. Heintz; came to the United States in 1930 to study the Arthrodire material in various 

 museums here. He worked at the American Museum for several months, chiefly with the 

 fossil remains of Dinichthys interynedius Newberry, assembled by Newberry, Dean and 

 others. The publication of Dr. Heintz;'s Article as no. IV in the Dean Volume is very 

 fitting since this enigmatic fish and its numerous fossil relatives had engaged Dr. Dean's 

 attention and study during many years. 



The scores of drawings for the plate figures of Articles II, III, VII and VIII were 

 made in part by Dr. Dean and in part by Japanese artists working in Japan and in New 

 York under his personal direction. Prepared in a technique suitable only for reproduction 

 by lithography, the majority are in pencil (gray) but many others are beautifully done in 

 the natural colors of the eggs and embryos. However, there was little uniformity in their 

 arrangement and in other essential features, and the final preparation of these plates 

 presented many difficulties to the editor and his assistants. It was not until each figure 

 had been photographed and the prints had been trimmed and arranged in dummy plates 

 that satisfactory plates for reproduction by lithography could be produced. 



The lithographed plates of Articles Nos. II, III, VII and VIII were made by the 

 well-known firm of A. Hoen and Company of Baltimore, Maryland. The head of the 

 firm, Mr. A. B. Hoen, took personal charge of our work. Being in New York frequently, 

 he came to the Museum, advised as to the order and arrangement of figures on the plates, 

 and later with authors and editor he studied the proofs of the plates and advised as to 

 corrections. The finished printed plates reveal the integrity with which the superb 

 originals have been reproduced. 



The printing of this Volume has been done in the Museum's Print Shop, at first 

 under Stephen Klassen, later under Edward Burns whose skill is reflected in the fine 

 typography and layout of the Volume. To printers Bailey Lewis, Dominick Caggana, and 

 Albion Haddon grateful appreciation is tendered for their excellent work. 



The very full Analytical Subject Index was prepared by Miss Jannette M. Lucas 

 with great care and skill. 



In short, it has been the aim of all concerned in the production of this 

 Memorial Volume to bring out a work worthy of dedication to the imperishable memory 

 of Bashford Dean.
