This thesis is confirmed especially by the abortive attempts to found journals, see HerrmannD. B., “Die Entstehung der astronomischen Fachzeitschriften in Deutschland (1798–1821)”, Dissertation, Section Physics, Humboldt University (Berlin, 1969), 23 (to be published in Publications of the Archenhold Observatory).

JahnG. A., Geschichte der Astronomie vom Anfange des 19. Jahrhunderts bis zum Ende des Jahres 1842 (Leipzig, 1844), gives the percentage of observatories in the various countries as approximately as follows: Germany 31%, England 16%, Italy 12%. An only slightly different picture results from the figures given by AiryG. B. in Abriss einer Geschichte der Astronomie im Anfange des 19. Jahrhunderts (Vienna, 1835), 11.

Ibid.363. Gould travelled with the Hungarian engineer, A. Neumann, whom he had met at the Altona Observatory. Neumann had been chosen by Karl Nagy—a well-educated and well-travelled promoter of astronomy in Hungary—to work at the observatory which Nagyerected in Bicske from 1845. Nagy had sent his assistant to Altona to gain practical training and experience. See KelenyiO. B., “Geschichte der Ungarischen Astronomie”, Astronomische Abhandlungen des Königlich Ungarischen Astrophysikalischen Observatoriums, i, no. 2 (Budapest, 1930), 83. When Gould arrived in Bickse the observatory was not complete, but part of the instruments were already there and he was able to see them. After the observatory ended its operations, its instruments were offered for sale in Gould's journal, see The astronomical journal, iii (1854), 104.

Correspondence between Gould and Schumacher continued until the latter's death, see also AJ, i (1851), 143. AN was well-known in America. Gould personally and a number of American bodies fought to save it during the confusions of the 1848–49 revolution. See Gould's letter to SchumacherH. C.
