The most striking feature of the book is the forty-eight life- 
size colored plates, reproduced from originals drawn from living 
plants—making it a volume of great beauty as well as of scientific 
importance. 
The American Florist. Lovers of irises owe a huge debt of gratitude to 
William Rickatson Dykes, who after years of labor has produced a 
magnificent work on these plants..... Mr. Dykes combines the 
scientist’s analytical skill with all the grower’s enthusiasm. 
The Florists’ Review. If anything else could be added to the book that 
would really increase its beauty or its scientific value or its practical 
utility, the present reviewer is curious to know what that addition

Byzantine and Romanesque Architecture. By Thomas Graham 
Jackson, R.A. Two Volumes, with 165 Plates and 148 ° 
Illustrations. 
Vols. I and II, each 294 pages, crown quarto, half vellum; two vols. $12.50, 
postpaid, $13.25 
This work contains an account of the development in Eastern 
and Western Europe of Post-Roman architecture from the fourth 
to the twelfth century. It attempts not merely to describe the 
architecture, but to explain it by the social and political history 
of the time. ‘The description of the churches of Constantinople 
and Salonica, which have a special interest at this time, is fol- 
lowed by an account of Italo-Byzantine work at Ravenna and in 
the Exarchate, and of the Romanesque styles of Germany, 
France, and England. Most of the illustrations are from 
drawings by either the author or his son, and add great artistic 
value to the volumes. 
The Nation. The two volumes must surely take their place among the 
standard classics of every architectural library.
