240 The Botanical Gazette. [April 
Of some statements we can find no explanation except that the author 
has mistaken the facts, but we cannot undertake to give illustrations 
of these. There is certainly confusion regarding the secondary bast 
fibers, that is those produced by the secondary meristem of the bundle, 
and the similar tissues arising from the pericycle. We cannot under. 
stand in what sense “tracheids are to the ducts what the accompany- 
ing [i.e., companion] cells are to the sieve-tubes of the phloem, namely 
assisting cells.” If mono- and dicotyledonous types of stem structure 
are distinguished, is it not a serious objection to such a distinction to 
have to say regarding monocotyledons which undergo secondary thick- 
ening that “the stems which do admit of such increase may be col 
sidered as having changed from the mono- to the dicotyledonous type?” 
And this is unintelligible: “In general it [the cambium ring] may 
said to be formed either by the intercalation of new bundles, or by 
the formation of interfascicular cambium.” Is this “what is com 
monly called bark, namely all that portion of the stem outside the 
Inner periderm?” 
So we turn from the book with regret, wishing it were better, and 
hoping that by a careful revision Dr. Gregory will be able to furnish 
us a much needed text-book. It ought to be suggested to the pub- 
lishers, also, that they seek to emulate the delicacy and softness of the 
illustrations in Strasburger’s works, and avoid the coarse harsh style 
in which they have produced these.

Drs. Rusby and Jeliffe have written for a pharmaceutical journal er
