and soon after rciulcivd famous by C. L. VAnme, liad since fallen 

 into nef,decl-, but had been somewhat rehabilitated during the long 

 service of Teysman, and the eleven years of directorship under 

 tSchefter. 'I he latter had started a department of Colonial 

 Agriculture, and a scientific journal emanating from the garden, 

 and restricted to systematic papers, under the title of 'Annates 

 du jardin botanique de iiuitenzorg.' Of this only the first volume 

 was completed by fcJclKil'er in 187G, when it stopped, until 

 resumed by his successor. 



In November 1880 Treub was settled at Buiten/.org, with 

 Tfv. W. Burck as his assistant, and soon determined that ti.e 

 'Annales' should bo continued on a wider basis, and not bo 

 confined to the concerns of Java. In the preface to the second 

 volume of that series the new editor explained how that adminis- 

 trative duties had hindered his predecessor from prosecuting the 

 work, but ho considered it his pious duty to put forward the only 

 paper found written by Sclieli'er, and that though his own work 

 had hitherto lain in the departments of plant anatomy and 

 l)liysiol()gy, he had no intention of confining the journal to 

 one department. Besides the contribution already inentioned. 

 Dr. Treub printed in this volume the first ]iart of his ' Hecherches 

 surges Cycadees ' and ' Observations sur les Loranthacees.' 



Treub may be considered as the first; botanist, trained in 

 modern method.s who has had the control of a botanic garden in 

 the tropical wonderland : of this he maile full use. Tew botanists 

 had used tlie microscope in the tropics: in India, GriHith had 

 employed the instruments of his day to good purpose, it is true, 

 but the new Director set himself to establish i)roper and adequate 

 means of research, amidst the gorgeous and abundant vegetation 

 surrounding his sphere of activity. He succeeded in making 

 Bmtenzorg a goal for visiting botanists, attracted thither bv the 

 prospect of employing material in abundance, quite unattainable 

 m temperate climates, and he also succeeded in establishing the 

 Agricultural Departmeiit on a scientific basis. With the adminis- 

 tration of the garden and the department just mentioned, his 

 energies, even in a climate which usually exhausts Europeans in 

 a few years, were still further employed in a series of researches 

 and observations which would have done credit to a man of 

 leisure. 



Prof. Goebel has pointed out that Treub's contributions to the 

 ' Annales ' niay be grouped under four heads. 



Pirst, his observations on the prothallia of the Lycoi)odiacea^, 

 extending over four volumes. Second, the work on Cycads, 

 Casuarina, the division of Angiosperms into chalazogamic and 

 porogamic plants, and Apogamy. Third, on Epiphytes and 

 Mlinnecodia, on climbing plants, and the renewal of vegetation 

 on Krakatau, tracing it from the third year after the eruption, 

 witli the occurrence of Cyauophycea) as rendering possible the 

 advent of Mosses and Ferns. Fourth, the continuation of his
