principally at the outer wall of the cells, chlorophyll cells trigonous, 
projecting between the hyaline cells at the hack. Basal intermediate 
leaves broadly bordered, with small rounded auricles. Betort cells 
of the branches straight, without any projecting neck. Catkins of 
male flowers subclavate, the bracts slightly secund, oblong, truncate, 
with several obtuse teeth, narrowly bordered, the areolation as in 
the branch leaves. Fruit seated in the coma, but little exserted, 
peduncular bracts oblong , scarcely bordered, innermost large, con- 
volute, emarginate, the hyaline cells rather small, lower narrow, 
upper suboblong, without many threads or pores. 
Hah., deep bogs, usually with S. subsecundum, for which it has 
probably been often overlooked. 
Near Holyhead and at Yale Boyal, Cheshire (Mr. Wilson), 
Loch Kandor, Braemar, 1868 (Mr. Hunt). 
Closely resembling some forms of S. subsecundum, but distin- 
guished by the pale hark of usually two layers of cells, and by the 
peduncular bracts ; the fruit, however, is very rare, and the drawing 
is from an American specimen, collected in Cranberry Marshes, 
Northern Ohio, by Sullivant in 1849, for which I am indebted to my 
valued friend Prof. Lindberg. The male plant is from specimens 
communicated by the late Mr. Wilson. 
II. — Reply to “ Further Remarks on Tolies ith and Powell 
and Lealand's Immersion pjh." 
By Dr. J. J. Woodward, U. S. Army. 
The July number of this Journal contains (page 13) an article 
entitled “ Further Remarks on Tolies’ 4th and Powell and Lealand’s 
-xVtli” (by Mr. E. Bicknell), which is so full of erroneous statements 
with regard to some of my work, that I cannot allow them to pass 
uncontradicted. 
I do not feel called upon to enter into a discussion of Mr. Bick- 
nell’s arguments, but merely discharge the disagreeable duty of 
showing that his premises are not true. 
He gives measurements of two of my positives on glass, each 
of which represents two frustules of Amphipleura pellucida, the 
one made by the first, the other by the second of the objectives 
above named. To these positives certain magnifying powers were 
attached. 
He then proceeds to assume that the two positives were taken 
by each objective, without eye-piece, at 48 inches distance, and that 
the frustules represented had each 95 striae to the rriuoth of an
