studies on native woods used for railroad ties and the fungi which 
destroy them, portions of which he has given before this club 
and other organizations. The plates are reproductions of his 
wonderful photomicrographs, and in most cases are excellent. 
The woods discussed and illustrated are those of Quercus alba, 
Castanea vulgaris, var. Americana, Chamecyparis spherotdea, 
Pinus palustris, Tsuga Canadensis, Lariw Americana and L. oc- 
cidentalis.

On a Fossil Marine Diatomaceous Deposit from Oamaru, 
New Zealand.—E. Grove and G. Sturt, F.F.R.M.S. (Journal of 
the Quekett Microscopical Club, Sept., ’86, Jan., 87, May, ’87, 
Aug., 87; pp. 50; seven plates, containing 123 figures.) 
This series of papers, just completed, is a most valuable and 
exhaustive report upon this unique deposit. It would seem as 
though the microscopic life of these far away islands of the 
Pacific presents as strange and unexpected features as do the 
higher plant forms and the fauna of those regions. Altogether 
the authors have recorded 273 species found in the deposit. Of 
these, they have figured and described 118 species as new. This 
may appear to be a large number, but an acquaintance with the 
deposit, and a careful comparison of the species figured with 
_ actual specimens, will afford convincing testimony that the num- 
ber is not too great. Indeed, one cannot help admiring the con- 
scientious care which the authors have exhibited in the investi- 
gation, and their careful regard for the rights of other investiga- 
tors. Not the least attractive feature of the paper is the plates, 
which are remarkably well executed. Co HK.
