232 BOTANICAL GAZETTE. 
Mr. Romeyy B. Hovau, of Lowville, N. Y., is preparing a work of very thin - 
sections of wood and accompanying text. The first volume, to be issued in the 
spring, will embrace twenty-five species, each with radial, tangential and trans: — 
verse sections. It promises to he superior to any work of the kind yet pub- 
lished, s 
E SEEM to be nearing a solution of the vexed question of the structure of 
the diatom shell; therefore the discussion becomes of some interest to botanists. 
Let us be thankful that there are found students who are not content with “re- 
solving” Pleurosigma or “fighting objectives some of the numerous 
“ test (?) objects,” “dry,” “in balsam,” with “central” or “ oblique” light! 
THe JouRNAL oF Mycoocy is announced as a new monthly journal, de- 
voted to fungi, edited by Prof. Kellerman, of the Agricultural College of Kan-_ 
sas, J. B. Ellis, of Newfield, N. J., and B. M. Everhart, of Westchester, Pa. It 
is to be issued in place of Schweinitzia, mentioned some time since. It proposes 
to give an account of the current literature of the subject with descriptions of 
new North American species and monographs of genera. 
JOURNALS THAT PUBLISH new species, or make any important announce- 
ments, should be compelled to print the date of their publication. A journal 
bearing the imprint of January, and distributed to its subscribers in March, is 
manufacturing priority in a wholesale way, and if any question of priority 
should arise, as is often bound to be the case in descriptions of new species, some 
very unjust decisions might be made. The Gazerre is ready to follow its ow 
estion.

WHAT IS BELIEVED to be the first described case of the occurrence of # 
three-sided conical apical cell in the leaf of any plant has been published by 
F. O. Bower, in the Proceedings of the Royal Society, of London. The apices of the 
young leaves of Todea superba and Osmunda cinnamomea are occupied by such 
cells, from the three sides of which segments are cut off in the usual way. The 
cell is so placed that one side faces the upper surface, while the other two stand 
obliquely to the under surface. The d iscovery is an important one, as it helps 
still further to bridge the gap between the Ferns and Cycadee.
