1873. the Materia Medica of the vegetable kingdom, and more and 

 ~ moU3 more matter constantly poured in to him. Though so much 

 workers, intellect and labour (comparatively more in earlier times than 

 IVrpira) now) have been expended on this department, still the verdict 

 Ouibourt. j g We ll_f unded, that no inquirer has ever worked upon such a 

 comprehensive, certain foundation as Daniel Hanbury. None 

 was fitted for it in the same degree, by a course of self-denying 

 education, by inclination, and by favourable outward circum- 

 stances. Clusius might perhaps be compared to him, if it were 

 allowable to apply the same standard to performances in natural 

 science, separated by two centuries and a half. Pereira, the 

 master so highly esteemed by Hanbury himself, grasped, as a 

 physician, a much wider theme, whilst Hanbury, working partly 

 at the same subjects, though from a pharmaceutical point of 

 view, knew how to develop this one side more effectually and 

 with more penetration, adducing the most perfectly reliable 

 information. Guibourt, held by the French the first authority 

 of his time, with as undisputed right as Pereira on the other side 

 of the Channel, differs essentially from the two Englishmen. 

 He was a very acute observer, who had come, like Hanbury, out 

 of the school of a rich practical experience, and in addition was 

 expert in the office of instructor, like Pereira. But Pereira's and 

 Hanbury's circle of vision was by so much the more extensive 

 as English influence exceeds French in the world. Guibourt 

 possessed less the power of understanding foreign circumstances, 

 less of that wealth of geographical, historical, and linguistic 

 knowledge, and of mercantile skilfulness which were peculiar to 

 Hanbury, and enabled him in so many cases, overleaping normal 

 bounds, to look back to the most remote sources. This significant 

 peculiarity of the latter is reflected in his works ; many of these 

 offer results of enduring value, which will not easily fall into 

 oblivion through the ceaseless advance of the stream of progress. 

 To such belong his papers of 1852 upon frankincense, 1 those 

 of 1854 on scammony, 2 the beautiful work upon cardamoms, 3 

 1855, the last was a permanent pet subject, which Mr.
