162 GLEANINGS. 
Fresuwater Lirs.—Mr. Bolton, 17, Ann Street, Birmingham, informs 
us that, in continuation of his report (pp. 97 and 127) he has sent the 
following additional objects to his subscribers :—Young Cristatella mucedo, 
just developed trom the statoblast ; Syncheta mordax ; Embryo of fresh- 
water Mussel, Anodonta cygnea; Nitella translucens, with Carchesium 
polypinum; Batrachospermum moniliforme ; Elver, or young Eel; Spawn 
of Perch; Melicerta ringens; Melicerta tubicolaria (or tyro;) Pandorina 
morum; Volvox globator; and Fredericella sultana. ‘These were, as usual, 
all illustrated by drawings from under the microscope by Mr. H. EH. 
Forrest, or by copies of Dr. Hudson’s, Professor Allman’s, Oersted’s, or 
other drawings, with appropriate descriptions. It is interesting to know 
that Mr. Bolton has found a new habitat for the rare rotifer, Melicerta 
tubicolaria, (or tyro,) of which Dr. Hudson gave a most interesting account 
and drawings in the ‘‘ Monthly Microscopical Journal,” November, 1875, 
(vol. xiv., p. 225.) 
Harpy Spring Frowers ofthe undermentioned kinds were exhibited 
in bunches, by Mr. W. Ingram, of Belvoir Castle, at the Conyersazione at 
Leicester, on the 20th of May, on the occasion of the visit of the Midland 
Union. They were in superb condition, and showed what glorious decor- 
ative resources for our gardens we have in plants which are sufficiently 
hardy to withstand the severity of such a winter and spring as we have 
just passed through. We urge our horticultural readers to make a note 
of this list, and select from it for the enrichment of their gardensfor next 
and future years. All the plants should be planted in the Autumn.

Parasires—A new work by Dr. Spencer Cobbold, F.R.S8., is 
announced, (publishers, Messrs. Churchill,) in which the author treats of 
the subject of parasites as it affects the whole animal kingdom. The 
Atheneum says the volume is divided into two books, the first dealing 
with the parasites of man, and the second with those of animals, including 
birds, reptiles, fishes, &c. Great attention has been given to the depart- 
ment of epidemics, (epizodty,) both as regards public health and the 
welfare of our domesticated animals. 
GroLocy AT THE CrysTaL Panace.—Do many of the visitors seek out 
the interesting illustrations of geological facts which are to be seen in the 
Palace and its grounds? Inside the building there is a good exhibition 
of flint implements, of specimens of fuel peat, lignite, all the varieties of 
coal, &c., and also sections showing the structure of the London Tertiary 
Basin. In the grounds there is, near the lake, the representation of a coal- 
field, the rocks, limestones, sandstones, grits, clays, and shales having 
been brought from the Yorkshire and Derbyshire coalfield. Mineral 
veins and caverns are seen, faults may be noted; Permian and Devonian 
beds are shown above and below. On the shores and islands of the lake 
are full-size restorations of various extinct animals, as the Labyrinthodon, 
Ichthyosaurus, Iguanodon, Palzotherium, &c. These were executed 
under the direction of Mr. Waterhouse Hawkins and Professor Owen.
