lectors, who continued, during a long series of years, to transmit dried 

 specimens from Nipal. Mr. Blinkworth, an active collector, at the 

 same time explored Kumaon, and Mr. Gomez contributed extensive 

 collections from the rich province of Silhet, and from the neighbouring 

 Khasia hills, while Wallich himself visited Penang and Singapore, thus 

 adding a knowledge of the Malayan Flora to that of the rest of India. 

 Abundant materials for the elucidation of the Botany of India hav- 

 ing thus been brought together, it became a question in what manner 

 they might be disposed of to most advantage. Dr. Wallich at one 

 time entertained the idea of incorporating them into an Indian Flora, 

 and with this object he commenced the publication of an edition of 

 Roxburgh's ' Flora,' into which all his own discoveries were introduced. 

 As his collections accumulated, this task became every day more diffi- 

 cult, and his other duties, and in particular the state of his health, 

 rendered its progress extremely slow, and at last compelled him to 

 stop, after publishing two volumes, which extend as far as the end of 

 Pentandria Monogynia in the Linnean arrangement, and include there- 

 fore the first volume of the ordinary edition of Eoxburgh, or less than 

 one-third of the whole work.

once liberally accorded, to distribute amongst scientific men, in all 

 parts of Europe, the materials which he had accumulated, but could 

 not hope to have leisure to work into shape, in the hope that each re- 

 cipient would be able to lend his aid to the study of some part, so that 

 by the joint labour of all, the Indian Flora might be benefited and fur- 

 thered. The result has been satisfactory. The dispersion of the Wal- 

 lichian Herbarium over all parts of Europe, enabled students of Botany 

 everywhere to obtain access to a set of these specimens, and monogra- 

 phers have, in describing them, uniformly quoted the numbers attached 

 to the specimens. The Wallichian Herbarium has therefore become 

 one of the foundations of Indian Botany, and it is a source of regret 

 to me that a set of its specimens does not form a part of our collection 

 here. Steps have recently been taken which will, I hope, remedy the 

 deficiency, as several duplicate sets still exist in the Linnean Society's 



collection. 



Those only can appreciate the difficulties with which Dr. Wallich 

 had to contend in this distribution, who have had much practice in the
