The Nature -printed British Sea-iveeds, a History, accompanied 

 by figures and dissections, of the Alga of the British Isles. 

 By W. G. Johnstone and Alexander Croall. Nature- 

 printed by Henry Bradbury. Vol. II, Rhodospermeae, 

 Fam. x — xiii. Vol. Ill, Melanospermeae. Vol. IV, 

 Chlorospermeae. London : Bradbury and Evans. 



In the first number of our present volume we noticed the 

 first volume of this beautiful work, and it is a matter of 

 surprise that we should be called upon to notice not only a 

 second, but a third volume, before the close of the year. 

 Such good speed is both creditable to publisher and authors, 

 for the work that has been done must not be measured by the 

 size of the volumes, but the care that has been bestowed both 

 on the letter-press and illustrations. The second volume 

 brings us to the end of the Rhodosperms, and is equally 

 successful with the first in giving the correct forms of these 

 charming sea-weeds. The third volume is devoted to the Mela- 

 nosperms, and here the nature-printer has had more than ordi- 

 nary difficulties to contend with, the thick and leathery forms 

 of bladder wracks, with the gigantic fronds of Laminaria, 

 seemed as if they would defy any attempt to induce them to 

 produce a presentable picture of themselves. But by selecting 

 young and delicate specimens, even Fucus nodosus and Lami- 

 naria digitata are made fit companions for those who trust 

 to artistic skill for a place on the drawing-room table. As in 

 the former volume, each nature-print is accompanied by 

 drawings of microscopic structure, which will be found of 

 great value to those who pursue their sea-side studies by the 

 aid of the microscope. 



The second volume is dedicated to Dr. R. K. Greville, of 

 Edinburgh, whose classical work on the ' Cryptogamic Flora 

 of Scotland ' is known wherever the science of botany is pur- 

 sued; and the third is appropriately inscribed to Dr. W. H. 

 Harvey, of Dublin, to whom all writers on the family of 

 Algae are so greatly indebted. Whilst going to press we 

 have received the fourth volume of this beautiful work, which 

 now forms the most complete monograph we possess of the 

 Algae of Great Britain. The last volume contains a synopsis, 

 an index, an introduction, and a bibliography.
