tlie difficulty of tlie undertaking, and tlie obstacles they must en- 

 counter. His paper should be read in connection with Dr. Pigott's 

 paper in the ' Monthly Microscopical Journal' for June, 1870. The 

 two papers afford the most complete account of these wonderful lines 

 that I have yet seen.

Brighton and Sussex Natural History Society. 



July 13th. — Ordinary Meeting. Mr. J. J. Sewell, Vice-President, 

 in the chair. 



Messrs. Ireland, D. B. Friend, and Dr. Tuthill Massy were elected

 for election in August. 



Mr. Gwatkin reported the receipt, for the Society's album, of seven 

 very beautiful photographs of microscopic objects, made and presented 

 by Dr. Hallifax, including sections of proboscis of blow-fly showing the 

 rasping teeth, poison bag of spider, teeth of medicinal leech, &c., and 

 a water-colour drawing, by Mr. Penley, of Swanbourne Lake, Arundel, 

 from a sketch taken by hun on the occasion of the annual excursion. 



Votes of thanks were passed to these gentlemen. 



Mr. H. C. Maiden gave an account of the great difficulties he had 

 encountered in killing a female puss moth, until she had laid her eggs. 

 Apparently killed on a Friday, after laying 175 eggs, she recovered, 

 and though repeatedly, to all appearance, killed on that and the three 

 following days, she did not die until she had laid in all 298 eggs. 

 Many examples were given by the gentlemen present of the extrusion 

 of eggs by moths, not only before death, but even in articido mortis or 

 when the thorax was stiff, and to all intents dead ; so great is the effort 

 of natm'e to propagate the species. 



Mr. Wonfor then read a paper " On the Annual Excursion to Arun- 

 del, on June 30th," in which the chief incidents of the day, and the 

 various objects seen and obtained, were very graphically and happily 

 described, and especial reference made to the courtesy and hospitality 

 of the Mayor of Arundel (W. W. Mitchell, Esq.), who invited them to 

 luncheon, and of his Grace the Duke of Norfolk, who granted permis- 

 sion to see the gardens and private grounds attached to the castle. 



Votes of thanks were passed to the Mayor of Armidel and to his 

 Grace the Duke of Norfolk.
