222 PEOCEEDINGS OF SOCIETIES. [^SCrna^ A prisma 



keep a record of the localities from whence they are derived. I am 

 very anxious to get some from the Pacific coast, where many species 

 differing from Brazilian species must be foimd. Gaudichaud mentions 

 the neighbourhood of Guayaquil, in Ecuador, as being particularly pro- 

 lific in these lianas. 



I will conclude with a notice of another species which was sent 

 me from the Liverpool docks by Mr. Griffiths, whose structure is so 

 puzzling that I know not whether to call it dicotyledonous or mono- 

 cotjledonous. It consists of a central spongy mass of woody tissue 

 apparently without medullary sheath, pith, or medullary rays, and 

 arranged in the form of a pentagon formed of semicircular lobes, 

 the whole being surrounded with what appears to be liber which has 

 shrunk away from the very thick and hard external bark, so as to 

 leave the woody core isolated within it. The core consists of woody 

 fibres, but half its area is taken up with wide-mouthed vessels. 



I may add that the whole of these lianas furnish beautiful objects 

 for the microscope. 



Mr. Forrest suggested that useful dyes might be obtained from the 

 plants described by Mr. Bailey. 



In reply to a question from the Eev. Brooke Herford, Mr. Bailey 

 stated that owing to a difference in the structure and general appear- 

 ance of some of the stems in his possession he had been led to suspect 

 that they were aerial roots of some of the plants he had exhibited and 

 described. 



Microscopical Society of Liverpool. 



The second meeting of the present session was held at the Eoyal 

 Institution on February 1st. 



The Secretary read a letter from Mr. Eichter, forwarded by Mr. 

 T. J. Moore, descriptive of his published photograi)h of Infusoria. 



Dr. Eickard then exhibited Mr. Eichter's photograph on the screen, 

 by means of the oxyhydi'Ogen light, after which a paper was read by 

 Mr. G. F. Chantrell, " On Winter Fishing in the Windsor Eeservoir." 

 The author, after a brief description of the reservoir' of condensed 

 water at the Liverpool Corporation Pumping Station at Windsor, 

 enumerated the various species of Infusoria and Eotifera which he had 

 found in this pond on Anacharis ahinastrum and Potaviogeton crisp us 

 throughout the winter. 



Of the species illustrated in Mr. Eichter's photograph, Mr. Chantrell 

 stated that he had found within the last fortnight, and chiefly in the 

 lukewarm portion of the reservoir. Rotifer vulgaris, DinocJiaris tetractis, 

 Pterodina patina, Floscularia ornata, Macrobiotus Hufelandii, Stentor 

 M'ulleri, and Vorticella nehulifera ; and at an earlier period he had 

 also foimd Stephanoceros Eichornii, Melicerta ringens, Aecistes longi- 

 cornis, and Cothiirnia imberhis. 



Other species, not figured by Mr. Eichter, that were found in the 

 same place during the winter were, Floscidaria cornuta, Brachionus 

 urceolaria, and B. BaJceri ; Scaridium longicaudam, Epistylis nutans, and 

 E. anastica ; Adinophrys Eichornii and A. Sol ; Podophrya fixa, Acineia
