June 20th, 1860. — The Secretary read a few extracts from a 

 private letter from Mr. Frembly, of Gibraltar, in which he refers 

 to the rotifera found in that neighbourhood : they differ very 

 little from the British species described by Carpenter, Henfrey, 

 &c. He found with them, free vorticella with spiral stalk or tail, 

 whilst in England the free vorticella is generally found without 

 tail. Its utility in the case of those living with such neighbours 

 is manifest, for the vorticella would now and again become in- 

 volved in the eddy made by the cilia of the rotifera, but invariably 

 before coming in contact did they succeed in escaping by the 

 muscular power of the tail, which by suddenly coiling enabled 

 them to throw themselves out of the influence of the current. 



Mr. Prembly had found one of the Algae of the chlorosperm 

 order, which was new to him, and of which he had not found any 

 description. He intends to send specimens for examination. 



A letter was read from Mr. Hepworth, of Crofts Bank, accom- 

 panying specimens of Sarcina, injected kidney, spores of Equise- 

 tum, Euglena, JBatracliospermum moniliformis of two kinds, some 

 diatoms, &c. 



Mr. Samuel Hardman, of Davyhulme, presented a few well- 

 mounted specimens of the larva of the wire-worm, willow moth, 

 Cimex, and Curculio. 



Mr. Mosley exhibited the living (so-called) skeleton larva and 

 pupa of the Corethra plumicornis (Pritchard), pupa of Ephemera, 

 marine Gammarus from Gibraltar, and aquatic Gammarus from 

 near Northenden, almost identical with each other ; the shell or 

 scales of the marine animal being most transparent. 



Mr. Brothers exhibited the tongue of a cricket, circulation 

 in the chara, «fcc. 



Mr. Dancer sent for exhibition a specimen of Topaz, with
