Botany and Zoology. 85 



Lille, under the direction of Prof. Bertrand, and in the new botani- 

 cal institute of the University of Liege, directed by Prof. Morren. 

 The intimate structure of stem, root and leaf is worked out and 

 exemplified under all modifications attendant upon age, level and 

 biological conditions, and the importance of recognizing these 

 conditions and states is insisted on. This treatise would be an ex- 

 cellent vade mecum and guide for any student who wished 

 to undertake serious work in vegetable histology. The style of 

 exposition is as clear as are the illustrative figures. Perhaps this 

 is because it is French. a. g. 



7. The following Catalogues should also receive notice : 



A Preliminary List of the Plants of New Brunswick: Com- 

 piled by Rev. James Fowler, M.A., now of Queen's College, 

 Kingston, Ontario. Published at St. John, N. B., 1885. — The 

 author has aimed " to exclude every species of which he had not 

 seen a specimen"; and this gives a real value to this catalogue. 

 Moreover, the ballast-deposit plants and those just escaping from 

 gardens are wisely placed in a separate list. The author mod- 

 estly calls his work a preliminary list, and in the title states that 

 it was compiled " with assistance of members of the New Bruns- 

 wick Natural History Society." He is one of the best and most 

 conscientious botanists of the Dominion ; and this list has partic- 

 ular interest in relation to the most northern limit attained by 

 many United States species. 



Check-list of North American Gamopetalce from Gray's 

 Synoptical Flora ; by H. N. Patterson, editor and printer. 

 Oquawka, Illinois. — We have neglected till now to notice this 

 neatly executed pamphlet, which follows the same author's List 

 of North American Polypetalse, from Watson's Index. Mr. 

 Patterson does all his work tastefully and well. 



Check-list of North American Mosses and Ilepaticm / 

 arranged from Mosses of North America by Besquereux and 

 James and the Descriptive Catalogue of Plepaticce by Under- 

 wood ; by Clara E. Cummings, Wellesley College. An indica- 

 tion of the increasing interest now taken in Mosses and their 

 allies through the facilities supplied by the two works from which 

 this list is compiled. 



Catalogue of the Phmnogamous and. Vascular Cryptog- 

 am,ous Plants of North America ; by Dr. J. H. Oyster, Paola, 

 Kansas. 1885. — This is also a check-list for convenience of bot- 

 anists in making exchanges. The species are numbered in succes- 

 sion, and run up to 9,750. It is better in print and proof-reading 

 than would be expected. There is evidently a considerable 

 demand for such lists, and the supply now seems adequate to the 

 occasion. a. g. 



8. Eggs of Echidna hystrix. — The discoveries of Dr. Haacke 

 and Mr. Caldwell are briefly mentioned in this Journal, vol. 

 xxviii, 475, and xxix, 74. Dr. Haacke gives additional results in 

 a communication of January 8, 1885, to the Royal Society of 

 South Australia. He states that the egg was about 15 mm long
