POPULAR SCIENCE REVIEW. 
an account of the discovery of the Zeuglodon Macrospon- 
dylus of Muller, and of the remains of Hydrachen in 
general ; by Dr. Albert Koch, Corresponding Member of 
various Scientific Societies. 12 pp. 8vo. New Orleans, 
1853.” 
The first of these pamphlets was printed when the Missourium 
was on exhibition at St. Louis in 1840-41 ; the second , when 
the skeleton was in Ireland, it having been taken to London in 
1841 ; the third , when Dr. Koch’s first collection of Zeuglodon 
remains was arranged and on exhibition as the 44 Hydrargos ” in 
New York ; the fourth , after his first Zeuglodon collection had 
been carried (in 1845) to Europe, and purchased (in 1847) for 
the Koyal Anatomical Museum at Berlin (where it was studied 
by Muller) ; and after another 44 Hydrargos” had been obtained 
by Dr. Koch (in 1848), in the vicinity of 44 Washington Old 
Court House, Washington Co., Alabama,” and had been trans- 
ported (1) to Dresden (where, through “eight months’ faithful 
labour,” it was set up by May b, 1849), and also (2) to Breslau, 
(3) to Vienna (1850), and (4) to Prague, and at each place put 
on exhibition ; but not to Munich, because 44 the only saloon 
disposable was too small for the exhibition ; ” and, finally, had 
come hack to its native country, 44 after it had established its 
just fame in Europe” as one of the 44 Hydrachen,” and been put 
on exhibition in New Orleans.* 
Still other accounts of earlier date are at hand in 44 Sill. Amer. 
Journal,” vols. xxxvi.and xxxvii. of 1839 ; the first (vol.xxxvi., 
p. 198) cited from a newspaper article of January 1839, which 
was evidently written by Dr. Koch (then Mr., the title of Doctor 
appearing first in 1845); the second (vol. xxxvii., p. 191), 
signed 44 A. Koch, proprietor of the St. Louis Museum,” and 
credited to the 44 St. Louis Com. Bulletin” of June 25, 1839. 
Further, a note on the bones at St. Louis collected by Mr. 
Koch was presented to the American Philosophical Society, in 
October, 1840, by Dr. W. E. Horner, and an abstract from the 
Proceedings of that Society is cited in vol. xl. (1841). 
It is evident from these documents that Dr. Koch was a man 
of enterprise, 44 an indefatigable collector.” The credit is also 
due to him of having performed a great service to science by his 
collections ; for these included one of the best skeletons of the 
Mastodon that has been unearthed, and two nearly complete 
* The skeleton was on exhibition in St. Louis as early as 1855 or 1856, as 
stated in “ Sill. Amer. Journal/’ II., xxi., p. 146, 1856 ; was there, as I learn 
from Dr. Lapham, sold to the Museum (Curiosity-shop) ; and thence, later, 
taken to Wood’s Museum in Chicago, where it ended its remarkable career 
in the great fire of 1871.
