"W. Kitclien Parker, Esq., President, in the chair. — A commu- 

 nication from the Chevalier Huyttens de Cerbecq was read, 

 having reference to the minute structure of the scales of insects, 

 and specially to Mr. M'Intire's observations thereon. Papers 

 were also read on the following subjects : — " On the Markings of 

 Battledore Scales of Lepidoptera," by Dr. Anthony, of Birming- 

 ham ; and " On the Nerves of the Capillary Vessels, and their 

 Probable Action in Health and Disease," by Dr. L. S. Beale. A 

 discussion followed the reading of Dr. Beale's paper, in which 

 Drs. Berkart, Marie, Leared, Lawson, and Messrs. Stewart and

November 24>tJi. — Professor Lionel S. Beale in the chair. A 

 paper was read by Mr. M. C. Cooke on " The Minute Structure 

 of Tremelloid Uredines (Podisoma),'^ in which the structure of 

 the Tremelloid masses, commonly found on juniper bushes, was 

 detailed, together with the results of the observations of Tulasne, 

 Oersted, and others on the germination and development of these 

 fungi, with a critical examination of the species described under 

 the genera Gymnosporangium aud Podisomn. It was held by the 

 author that no good foundation existed for the constitution of two 

 genera, since the minute structure and development of both were 

 identical. Some conversation ensued on the phenomena of alter- 

 nation of generations which these and other fungi present, and 

 especially in cases where some of the phases of existence were 

 presumed to be passed on different hosts. Especial reference was 

 made to the opinions entertained by Professor Oersted that the 

 Podisomas were found in one state parasitic on leaves of Poma- 

 ceous trees, as E-oesteliaa, &c., in another stage inhabiting the 

 branches of junipers, as Podisoma, The author of the paper did 

 not consider that this supposed phenomenon was satisfactorily 

 proved. — Nature.
