their botanical acquirements. Both are considerable contributors 
to the Botanische Zeitung, a periodical work which contains 
Treatises, Reviews, Extracts, and new information relative to this 
science, published by the Botanical Society of Ratisbon ; and 
they have also, if we are not mistaken, edited conjointly, speci- 
mens of their discoveries made during the tour in question. 
Dr Hoppe, who resides at Ratisbon, has, notwithstanding his 
advanced age (which, together with his highly respectable cha- 
racter, has obtained him the title of the “ Nestor of German 
Botanists), undertaken several extensive alpine journeys, in search 
of the plants of his native country. These he has made known 
to the public through the medium of his Botanische Taschen- 
buch , for the years 1790,-91, &c. ; of his Herbarium vivum 
pfantarum rariarum prasertim alpinarum , 4 cent, in folio ; 
and particularly of his beautib.il Decades of specimens of Ger- 
man Grasses, which are now in the course of publication. 
Dr Hornschuch, the favourite pupil of the venerable Hoppe, 
is Professor of Natural History in the University of Griefswald, 
a town of Pomerania, on the shores of the Baltic Sea, and has 
the charge of the Botanic Garden there, established by the 
Prussian Government. Cryptogamic plants have occupied much 
of this gentleman’s attention, and his history of the two new 
genera of Systylium and Voitia , his account of some foreign 
mosses in the Hora Physics Berolinenses, and his Memoir 
upon the propagation and metamorphoses of the lower orders 
of vegetables, published in the Nova Acta Physico-Medica 
Acad. Cas. Leop. Car. Nat. Curiosorum , shew him to be per- 
fectly master of this subject ; add to which, in company with 
the celebrated Dr Nees Von Esenbeck of Bonn on the Rhine, he 
is considerably advanced in the publication of a German Musco- 
logia, the appearance of which the lovers of that beautiful fa- 
mily of plants are anxiously and almost daily expecting. The 
preface of the work which we are about to notice, commences 
by an apology for the plain and simple style of the nar- 
rative, which is professed to be chiefly written for the per- 
usal of travelling naturalists, und goes on to acknowledge, with 
grateful feelings, the assistance which the writers received du- 
ring their journey, from many individuals, several of them men 
high in rank aiid in literary reputation. The remainder of the?
