WARD’S NATURAL SCIENCE BULLETIN. 
Passing over the Permian and Trias with 
mere mention of a slab (5 feet long) of Cheiro- 
therium tracks from Germany, and a slab con- 
taining seven perfect heads and stems of Encrinus 
liliiformis. This latter is the original of No. 919 
“Ward’s Casts of Fossils,” and is undoubtedly 
the finest in America. 
In the Jurassic is at least one slab of Crinoids 
that deserves to rank with it. This is 5 feet long 
by 2 feet wide, and shows on an unbroken sur- 
face over twenty perfect expanded heads with 
long sterns of Pentacrinus briareus, from Lyme 
Regis, England. A single individual of another 
species (P. subangularis) covers a slab 3x2 feet, 
and others are nearly as large. 
The Ammonites from the Trias, Jurassic and 
Cretaceous together form a suite second to no 
other in the country, if we except those in the 
Agassiz Museum and in the University of Roch- 
ester. But the reptiles in this Age of Reptiles 
are after all the most valuable, and in this divi 
sion, considering the number and perfection of 
the specimens, the collection stands quite un- 
equalled on this continent. Among a number 
of perfect skeletons of Ichthyosaurus, the largest 
covers a slab 11x4 feet. Complete skeletons of 
Teleosaurus and Plesiosaurus cover slabs but 
little smaller, and many other Saurians are rep- 
resented by heads, paddles, vertebrae, etc. The 
fish rank close to the reptiles, and among them 
are a number of the originals of “ Ward’s Casts.” 
In the Cretaceous the Sponges are well repre- 
sented, among them being a “Paramoudra” (24 
inches in greatest diameter) from the chalk beds 
of Moira, Ireland. This is the original of No. 
1191 “Ward’s Casts - ” The Cretaceous is also 
rich in Mollusks, especially in the Lamelli- 
branchs, the collection of Rudistes being unusu- 
ally choice even for a European Museum. 
The Tertiary is represented by hundreds of 
genera and species from three continents; among 
them a fine suite of Leaf-impressions from the 
Oeningen beds; Echinoderms and Crabs from 
the Jebel Mokattam; a splendid series of Mol- 
lusks from the Paris and Vienna basins, includ- 
ing half a dozen Ceritliium giganteum, one 22 
inches in length, the original of No. 618 “Ward’s 
Casts. ” 
But we must bring this brief notice of the 
collection to a close by merely mentioning the 
fact that it contains four mounted skeletons of 
the Moa from New Zealand (one standing 8 feet 
high); a very perfect, mounted skeleton of the 
great Irish Elk; as also a mounted skeleton of 
the Cave Bear (the only other mounted specimen 
in America, we believe, is in our own collection); 
and finally a well mounted and well-preserved 
skeleton of Mastodon giganteus.

ranged stratigraphically, and contain 100 and 110 
respectively; the former is a general stratigraph- 
ical collection, the latter a characteristic series 
of the Rocks of the New York system, the 
types of the Silurian and Devonian in America. 
The satisfaction these collections have given is 
shown by the following sample letter recently 
received from Prof. Chickering. 
“The box containing stratigraphical series 
came in good order and its contents now fill 
their places on our shelves to my great satisfac- 
tion. I am greatly pleased with the quality of 
the specimens and the manner of mounting, and 
shall hope to send you further orders in the 
future. J. W. Chickering,

Under the heading of 
PHENOMENAL GEOLOGY. 
we have grouped together a collection of 75 spe- 
cimens which illustrate the different phenomena 
of Dynamical and Structural Geology, such as 
faults, veins, metamorphism, varieties in struct- 
ure and texture, &c.' 
Further are 
RELIEF MAPS. 
of especially interesting geological regions, such 
as Vesuvius, Etna, Mt. Blanc, Isle of Palma, 
Auvergne, Colorado Canon, Henry Mts., &c. 
These maps are exact models of the regions rep- 
resented, made to a definite scale, thus showing 
at a glance all the topographical features in 
their correct proportions. Colored as they are 
geologically, they not only show the relations of 
the different formations to each other, but illus- 
trate the structure as well, and show the entire 
dependence of the topography on them, thus 
proving invaluable aids in the study of physi- 
cal geography as well as geology, and at the 
.same time very ornamental and attractive objects 
in a museum. 
The features of structure and erosion are still 
more graphically illustrated by means of a series 
of stereograms, which show the country as it 
would be folded and faulted without erosion. 
We also have in this department a series of 
dissecting models in wood which show more 
clearly than is possible in diagrams the effects of 
erosion, veins, faults, outcrops etc. Finally, we 
have geological charts of all kinds, pictures 
of ideal geological landscapes, byDr.Unger, 
RESTORATIONS OF EXTINCT ANIMALS by W ater- 
house Hawkins, and a set of Water Color Draw- 
ings of characteristic fossils comprising 
Graptolites , Zoantharia, Echinodermata, Mollusca 
Crustacea , for details of all of which see General 
Catalogue of Geology and Lithology; 52 pages; 
price 20 cents.

York system; 44 pages; price 20 cents. 
Palaeontology — Fossils. 
We have on hand at the present moment a 
large and unusually rich store of actual Fossils. 
We have used great care to keep our drawers 
free from all but perfect, distinct, well-preserved 
specimens. From these we offer — at the option 
of the purchaser — either individual specimens , or 
we will make up, for any given sum, collections 
representing either a particular age or all geologi- 
cal epochs. The richness and extent of our 
material give us unprecedented facilities for 
doing this. 
A few of the more noteworthy forms are — in 
the Cambrian numerous fine examples from 
Canada and Northern New York of that much- 
disputed fossil Eozoon Ganadense. Also good 
specimens of at least two species of the oldest 
British plant Oldhamia. In the Silurian we 
offer among Foraminifera Receptaculites from 
Illinois, and gigantic sponges of the genus 
Stromatopora from the Calciferous of New York. 
Among Crustacea perfect specimens of Euryp- 
terus and Trilobites. In the Devonian numerous 
fine specimens of the strange Diciyophyton from 
the Chemung Group, and the interesting sup- 
posed Lamellibrancli Calceola as well as Fishes of 
different genera from the Old Red Sandstone of 
Scotland. In the Carboniferous, fine leaf- 
impressions of many genera and species ( Pecop - 
teris, Neuropteris , Alethopteris, etc.), as well as 
roots and stems of these and other Cryptogams. 
Extensive series of Crinoidea from Burlington 
and Crawfordsville, and some noble examples of 
Melonites from the St. Louis Limestone. Also 
beautiful Archimedes. In the Trias, fine slabs 
of various size of the interesting Reptilian tracks 
(Ichnites) from the Sandstone of the Connecticut 
Valley, first brought to the notice of scientists by 
Dr. Hitchcock as “Bird-tracks.” In the Lias, 
large slabs of Crinoids (especially Pentacrinus 
briareus and subangularis) from the celebrated 
localities of Lyme Regis, England, and Boll, 
Wurtemberg; as also Saurian remains in every 
degree of perfection. Cephalopoda ( Ammonites , 
Nautilus, Belemnites) in abundance. In the 
Oolite, Insects, Crustaceans and Fish from the 
Lithographic Slates of Solenhofen. In the 
Cretaceous, handsome leaf-impressions of An- 
giosperms of the genera Sassafras , Platanus , 
LJquidambar, etc., from the Dakota Group of 
Kansas. Among Spongidse notably Chenen 
dopora, Coeloptychium , and Ventriculites— the lat- 
ter including the variety known by Buckland’s 
name of Paramoudra— chiefly from the Green- 
sand and Chalk of England and France. Like- 
wise Echinodermata ( Micraster , Ananchytes, 
Galerites, Goniaster , etc.). Also Lamellibranchs 
— Ilippurites , Sphcerulites and the other singular 
forms composing Lamarck’s great family of 
Rudistes. In the Tertiary, we have a large 
series of finely-preserved Mollusca from the 
Claiborne beds of Alabama, the Eocene beds 
(D’Orbigny’s Parisien) of the Paris Basin, and 
the Moicene deposits around Vienna. Num- 
mulites from the Great Pyramid, and excellent 
specimens of the Echinoderm Clypeaster Gize- 
hensis from Gizeh, Egypt. Also the interesting 
Crustacean Lobocarcinus from the Jebel Mokat- 
tam. In the Quaternary, numerous remains 
of Proboscideans (Elephas and Mastodon ), con- 
sisting of bones and teeth, and including the 
skeleton of Mastodon giganteus found near New- 
burgh, N. Y., in 1879. Also remains of the 
Great Cave Bear and Hyena , of the former a 
complete mounted skeleton, the only one (with 
the exception of that at Princeton) in this 
country; and several complete skeletons of the 
great struthious birds' {Moa) of New Zealand. 
Finally Corals and Shells from the Raised 
Beaches along the Red Sea. 
Casts of Fossils. 
In addition to the actual fossils from the 
different geological periods, we still continue to 
furnish “ Ward’s Casts of Celebrated Fos- 
sils.” These are copies — exact facsimiles in 
form and color — of both celebrated and typical 
fossil forms, from the British Museum, Jardin 
des Plantes, Vienna Museum, St. Petersburg 
Museum, and other noted cabinets of Europe 
and America. These were moulded in these 
institutions about fifteen years ago. As this 
method was the only one by which these treas- 
ures illustrating the early life on our planet 
might be brought within the reach of American 
studeuts, studying on American soil, the enter- 
prise was undertaken with a conviction of its 
utility to educational science, and with a confi- 
dence that the service would be appreciated. 
This confidence has not been disappointed. 
The call for these casts has been large, and is 
steadily increasing. Our highest institutions of 
seience have been the first to recognize their 
value and secure their aid. The following insti- 
tutions are among those who have endorsed these 
casts in the most unmistakable manner by order- 
ing from $1,000 to $3,000 worth: Smithsonian 
Institution; New York Geological Cabinet; 
Philadelphia Academy of Natural Scien- 
ces; Boston Society of Natural History; 
University of Virginia; University of Cali- 
fornia, and twenty others. Considerable 
numbers have also been sent to the Museums of 
England, Austria, Bavaria, South America, 
India, New Zealand, and Australia. 
The orders which have been received during 
the past years have indicated the fact that certain 
forms in this large series are more constantly 
preferred. This has decided us to make up 
three considerable suits or series of these casts, 
including in them, severally, those forms which 
have proved to be of more particular attractive- 
ness and interest for our lesser and our larger 
institutions. In this way three distinct Geologi- 
cal Cabinets have been compiled, but of different 
magnitude and scope. These comprise the
