in 1830, and who subsequently published a memoir, entitled, ' Re- 

 cherches generales sur I'organograi^hie, la physiologic, et I'organo- 

 genie des Vegetans,' * in which will be found a large number of 

 engravings of many lianas, but very little descriptive matter ; the 

 memoir was written to support the views of Du Petit-Thouars in regard 

 to the growth of wood, and in opposition to the views of other leading 

 botanists, but little is said about the climbing jjlants. The most com- 

 plete general account of their structure which I have met with is 

 that by Adrieu de Jussieu — ' Sur les tiges de diverses Lianes, et 

 particulierement sur celles de la famille des Malpighiacees ;'■!■ this was 

 afterwards reprinted, with additions, and incorporated in the same 

 author's ' Monographic de la famille des Malpighiacees.' | Another 

 account of their organization is included in the eighth volume of the 

 ' Botanische Zeittmg,' by Hermann Criiger, entitled ' Einige Beitrage 

 zur Kenntniss von sogenanntnen anomalen llolzbildungendes Dikoty- 

 lenstaraines,' and published in 18.50. Notices of the structui'e of other 

 lianas are also to be met with in isolated memoirs, some of which 

 will be referred to, and in most botanical text-books, particularly 

 in those of Lindley, Schleiden, Richard, and Duehartre. Much im- 

 portant information may also be anticipated from some recent memoirs 

 by a Brazilian botanist — Dr. Ladislali Netto, who has presented me- 

 moirs on the subject to the French Academy, extracts from which have 

 only so far been published in the ' Comptes Rendus ' and ' Annales des 

 Sciences ' for 1866, 1867, &c. § 



Microscopical and Natural History Section of the Manchester 

 Literary and FhilosopMcal Society. 



January 3rd, 1870. R. D. Darbishire, B.A., F.G.S., in the chaii-. 



Dr. Wm. Roberts exhibited some specimens of urinary calculi, 

 composed of cystine ; also some crystals of the same, obtained by eva- 

 poration in the open air of the ammoniacal solution. Six-sided plates 

 of mother-of-pearl lustre were obtained in this way, which formed 

 brilliant objects for the microscope. 



Mr. J. vSidebotham read a paper, entitled " Notes on the Pui)a and 

 Imago of Acherontia atropos.'" 



Mr. W. Boyd Dawkins, F.R.S., sent for exhibition some very inte- 

 resting microscopic sections of Eozoon Canadense, which are the more 

 valuable as being those which have passed through the hands of Sir 

 W. E. Logan and Dr. Carpenter. 



Mr. J. B. Dancer, F.R.A.S., presented the Section with a box ciju- 

 taining twelve new polarizing objects. These partly consisted of some 

 of the hard fatty acids which form very eftective objects, and partly of 

 crystallizations of some of the hydro-carbon compounds which compete 

 with the best specimens of polarizing objects of the present day.
