proaches to Appendicula, the flower of which however does 

 not depart from the ordinary structure of a natural section 

 of Vandeae. 



I see nothing in Lindley's Gen. and Spec, approaching it 

 technically except Appendicula, from which however it is too 

 distinct to need any comparison.

Extract of a letter from M. Guieourt, Professor of Pharmacy, Paris, to 

 Dr. Mouat, Professor of Materia Medica, Calcutta. 



To the Editors of the Calcutta Journal of Natural History. 



Dear Gentlemen — I am induced to forward to you for publication in your 

 Journal, the enclosed extract from a letter addressed to me by Professor Guibourt 

 of Paris, because it will be the means of widely making known, what are deemed 

 by the first authorities in Europe, desiderata respecting the Materia Medica of 

 India. I have succeeded in collecting a few specimens, and also some definite 

 information respecting certain of the substances mentioned by Monsieur Guibourt; 

 but my time is so fully and incessantly occupied in more immediate and pressing 

 official duties, that 1 am quite unable, single-handed, to do justice to so important 

 and interesting a subject. 1 venture, therefore, to solicit the aid and co-opera- 

 tion of all who take an interest in the matter, and are able from leisure and favour- 

 able position to collect specimens, and furnish me with any information concern- 

 ing them. I shall be happy to defray every expense attendant upon collecting, 

 packing, and transporting all specimens with which 1 may be favoured, and of 

 acknowledging them, with the source from which they were derived, through the 

 medium of your valuable Journal, if you will accord me your kind permission to 

 do so.
