increased.  He became care-worn and haggard in his looks, often complaining of anomalous symptoms, marked by an extreme rapidity of pulse, in consequence of which he had left off wine for some years past, and was obliged to observe great care and attention in his diet.  In Affghanistan he was very nearly carried off by fever, to which he had been subject in his former travels in Assam.  No government ever had a more devoted or zealous servant, and I impute much of the evil consequences to his health to his attempting more than the means at his disposal enabled him to accomplish with justice to himself.”

“The most important of Mr. Griffith’s published memoirs are contained in the Transactions of the Linnaean Society.  Previous to starting on his mission to Assam, he communicated to the Society the first two of a series of valuable papers on the development of the vegetable ovulum in Santalum, Loranthus, Viscum, and some other plants, the anomalous structure of which appeared calculated to throw light on this still obscure and difficult subject.  These papers are entitled as follows:—­

1.  On the Ovulum of Santalum album.  Linn.  Trans. xviii. p. 57.

2.  Notes on the Development of the Ovulum of Loranthus and Viscum; and on the mode of Parasitism of these two genera.  Linn.  Trans. xviii. p. 71.

3.  On the Ovulum of Santalum, Osyris, Loranthus and Viscum.  Linn.  Trans. xix. p. 171.

“Another memoir, or rather series of memoirs, “On the Root-Parasites, referred by authors to Rhizantheae, and on various plants related to them,” occupies the first place in the Part of our Transactions which is now in the press, with the exception of the portion relating to Balanophoreae, unavoidably deferred to the next following Part.  In this memoir, as in those which preceded it, Mr. Griffith deals with some of the most obscure and difficult questions of vegetable physiology, on which his minute and elaborate researches into the singularly anomalous structure of the curious plants referred to will be found to have thrown much new and valuable light.

“In India, on his return from his Assamese journey, he published in the ‘Transactions of the Agricultural Society of Calcutta,’ a ’Report on the Tea-plant of Upper Assam,’ which, although for reasons stated avowedly incomplete, contains a large amount of useful information on a subject which was then considered of great practical importance.  He also published in the ‘Asiatic Researches,’ in the ’Journal of the Asiatic Society of Bengal,’ and in the ’Transactions of the Medical and Physical Society of Calcutta,’ numerous valuable botanical papers; but the most important of his Indian publications are contained in the ’Calcutta Journal of Natural History,’ edited jointly by Mr. MacClelland and himself.  Of these it may be sufficient at present to refer to his memoir “On Azolla and Salvinia,” two very remarkable plants which he has most elaborately illustrated, and in relation to which he has entered into some very curious speculations; and his still unfinished monograph of “The Palms of British India,” which promises to be a highly important contribution to our knowledge of a group hitherto almost a sealed book to European Botanists.
