128 JOURNAL OF THE [November, 



BRYOZOA. 



Mr. Damon : " Whoever sails through the Gulf Stream is sure 

 to encounter extensive fields of the floating sea-weed called 

 Sargassum. When closely examined it is seen to be laden with 

 little spherical air-vessels which serve to float it. Many of these 

 will be found to be completely enveloped in a lace-like calca- 

 reous case, a rare specimen of marine architecture, which remains 

 entire even after the death of the colony of Bryozoa which 

 formed it. An attempt has been made by an expert jeweller to 

 copy this delicate structure, in gold, as an ornament ; but suc- 

 cess was impossible — so fine and intricate was the model found 

 to be. 



" Sargassum is a rich field for the microscopist, being the 

 habitat of many interesting creatures besides Bryozoa. Among 

 these are myriads of minute, gorgeously-colored crustaceans, 

 and many forms of the beautiful Sertularia, and a small fish 

 which has a curious dorsal lock-hinged fin, and, being of the 

 same color as the plant, is often overlooked by the collector." 



Mr. Schultz said that he had been requested to present to 

 the Society on behalf of Mr. Charles E. Ailing, of Rochester, 

 N. Y., a copy of a blank-book published by Mr. Ailing, entitled 

 " Microscopical Records," and containing suitable blanks for 

 cataloguing and describing five hundred slides, with an index 

 and space for recording and preserving Formulas used in 

 preparing specimens. 



On motion, the thanks of the Society were extended to Mr. 

 Ailing. 



Mr. Ludwig Riederer was elected an Active Member of the 

 Society.
