upon the Fisheries,” published in 1773, was published a translation of 
Jacobi’s memoir on artificial propagation. [DUHAMEL DU MONCEAU: 
Traite General des Peches, publie par ordre de l’Academie des Sci- 
ences. Paris, 1773, part ii., p. 209.] 
V. 1771—First Recognition by Governments of the Importance of Fish 
Culture.— George III., of England, recognizing the importance of the 
discowery of Jacobi, granted to him a life pension. [PEZAY: “ Soirees 
Helvetiennes,’ Amsterdam, 1771, p. 169. MILLET: op. cit., 1870, p. 128.] 
VI. 1772—First Public Demonstration of the Principles of Fish Cul- 
ture —In 1772, Prof. Adanson, in his lectures in the Royal Garden of 
Paris, now the Garden of Plants, demonstrated to his hearers by prac- 
tical illustration the processes of fish culture. [MILLET: op.cit., p. 128.] 
VII. 1788—Fierst Publication in English of a Treatise on Fish Cul- 
ture.—A translation of Jacobi’s memoirs was published in London, in 
1788, under the title, “S. L. Jacobi’s Method of Breeding Fish to Ad-

VIII. 1791—Begénnings of Fish Culture in Ttaly—As early as 1791, 
Joseph Bufalini, of Cesena, in Northern Italy, had succeeded in arti- 
ficially fecundating the eggs of many species of fish. [Opzscold Scelt¢ 
di Milano, XV.,1791. Vis Litteratre de Spallanzanz, by Tourdes, p. 63.| 
Little has, however, since been done in Italy, particularly in the way 
of public fish culture. 
IX. 1800-1840— The Work of Early Disciples of Facobt in Germany.—- 
As we have already seen, the son of Jacobi carried on fish culture at 
Hohenhausen from 1784 to 1825. According to Hartig and Von Kaas, 
the forester Franks, and perhaps others, practiced successfully the 
methods of Jacobi at Steinburg, in Lippe Schaumburg, soon after their 
promulgation. Head-forester Martens made some successful trials at 
Schieder in 1827, which were continued for many years. In 1837, 
Court-hunter Schnitger, a pupil of Martens, established in Lippe Det- 
mold, Jacobi’s own province, a trout-breeding establishment, which, in 
1844, was still in successful operation. Here were made some inter- 
esting observations upon the influence of temperature on the develop- 
ment of eggs. In 1840, Knoche published an account of successful 
experiments at Oelbergen. [HArtTIG (Ernst Friedrick): Lehrbuch der
