LANCASHIRE AND CHESHIRE ENTOMOLOGICAL SOCIETY. 



February 12, the President (Mr. S. J. Capper, F.L.S., F.E.S.) in the chair. Miss 

 E. H. Lea, Kirb y Park, West Kirby, and Mr. Frederick Rose, 64, Mount Pleasant. 

 Liverpool, were elected ordinary members of the society. Mr. Robert Newstead, F.E.S. , 

 read a paper entitled, " Correlations of Plants and Insects."' in which he discussed the 

 fertilization of the Yucca, and explained the process as described by Prof. C. V. Riley in 

 r Insect Life," and added some notes from his own observation on the insects frequenting 

 the flowers in this country. He also gave notes on the gall-making Brachyscelidse of 

 Australia, a group of coccidas peculiar to that country. He also called attention to the 

 galls of Diplosis rumicis (Linn.), and suggested that it is quite possible botanists have 

 described malformed "tubercles" of some species of Runex, as he had found a great 

 number of " tubercles " abnormally swollen by this species. The paper was illustrated by 

 diagrams and specimens, including a specimen of gall-making coccidse from Australia. 

 The president exhibited a yellow variety of the variety confluens of Zygoma trifolii, taken 

 by Mr. W. M. Christie in West Sussex, Mr. Gregson a specimen of Arctia caja, with dark 

 nervures, Mr. H. B. Jones a number of Scotch lepidoptera, Mr. Stott Calosoma inquisitor

MANCHESTER MICROSCOPICAL SOCIETY. 



The ordinary meeting of the Manchester Microscopical Society was held at the Grand 

 Hotel on Thursday, the 22nd February, the new president, Professor Weiss, B.Sc,. 

 F.L.S., F.R.M.S.. in the chair. A testimonial, consisting of an illuminated address and 

 a number of standard works, was presented to Mr. James Hart, F.C.S., in recognition of 

 the services he has rendered to the society as honorary secretary for over four years. A 

 committee was formed for the purpose of obtaining subscriptions for a memorial of the 

 late Professor Marshall, who was the president of the society for the seven years 

 1887-1893. 



The President gave a lecture on " Recent Researches and Speculations on the 

 Structure of Protoplasm." The lecturer traced the recent advances in the knowledge of 

 the minute structure of protoplasm. The minute or microscopical structure of protoplasm 

 has been a more recent field of research than almost any biological investigation. The 

 older researches do not date back to much before 1880, and all those considered were of a 

 later date. The granular theory put forward by Hanstein in 1882 has received an impulse by 

 more recent investigations of Altman and Saftigen, who observed those granules actively 

 dividing in some cases, and compared them with micrococci and bacteroids, and suggested 

 some homologies. The fibrillar theories put forward by Flemming, Camillo. Schneider,.
