72 Report of the Progress of Vegetable Physiology in 1836. 



by skilful artists of what they have seen. This example Link 

 intends to follow, and in this way all those who are not able 

 to make microscopical observations themselves, will still have 

 the means of teaching themselves and others ; for drawings are 

 quite as necessary for the study of vegetable physiology as for 

 tiie study of anatomy. The great success which this work 

 has already experienced from its excessively moderate price 

 proves its usefulness. From the numerous beautiful and in- 

 teresting figures, we will only notice a few, which must attract 

 the attention of all botanists ; as the very successful representa- 

 tion of the interlacement of the ligneous bundles in the inter- 

 nodia of monocotyledons. Tab. ii. fig. 6. exhibits the inward 

 growing and interlacement of the ligneous bundles, which 

 descend from the branch or bud of Saccharum qfficiiiarum. 

 The germinating plants of various monocotyledons, the dia- 

 gonal sections from various anamorphoses of the monocotyle- 

 donous stem, the figures of the thickened cellular masses from 

 the bark of the birch, &c. exhibit at the same time much that 

 is new and which had never before been published. 



I have also a dissertation of my own to mention, sent in as 

 an answer to the prize question made by the Teyler's Society 

 of Haarlem on the 1st of January 1854, and which appeared 

 at the end of last year as the 22nd part of the Verhandclingen 

 witgegeven door Tcylcr's Tweede Genooischap (Haarlem^lHSG, 

 4to.). Although tliis work was not yet perfected for publica- 

 tion, yet I must return my thanks to the Society, as they have 

 published on this occasion a great number of my microscopi- 

 cal, for the most part phytotomical, drawings, which were given 

 with this publication on twenty quarto plates, and which it 

 would have been difficult to have done in any other way. 

 This dissertation has the title : " On the recent progress of 

 the Anatomy and Physiology of Vegetables"; it was, however, 

 written in 1834, and one part of the plates executed in 1833. 

 I might recommend the plates of this memoir for use ; for 

 although made for the most part with an old English micro- 

 scope, they might yet rank among some of the most correct 

 which have hitherto appeared for vegetable anatomy. The 

 new data which are contained in this memoir will be pretty 

 completely found in the book which lately appeared in Berlin 

 under the title: *' New System of Vegetable Physiology*."
