The following excursions took place : — 



May 27th. To Oak Avenue and Jumper's Ponds. 



June 14th. To Hatchett's Pond, between Beaulieu and 

 Lyndhurst. At each of these excursions several interesting 

 specimens were obtained. 



July 1st. To the Salterns, Parkstone, where it was hoped that 

 members might observe the numerous birds usually to be seen on 

 the marshes, but unfortunately some mischievous boys had drawn 

 the sluice-hatch the day before and let in the Hood tide, which turned 

 the marsh into a lake. This also prevented any hunting in the 

 marsh pools, so that searching for organisms was practically con- 

 fined to the piles of the Salterns Pier, where some interesting 

 specimens were found. The party then adjourned to the 

 neighbouring residence of Dr. Crallan (Chairman of the Zoological 

 Section) for tea. Afterwards the party inspected part of Dr. 

 Crallan's collection of Lepidoptera. 



There was no excursion in August owing to the drought. 



In September a dredging excursion in Poole Harbour was 

 proposed, but fell through owing to inclement weather. 



The following specimens of interest have been collected during 

 the summer : — 



Lepidoptera — A fine and unusually symmetrical albino variety 

 of Epinephele janira (a female). 



A well-marked aberration of Chrysophanus phlceas, the left 

 fore-wing being silvery white, as in the well-known var. schmidti. 



A female Lycaena bellargus (adonis), in which the usual 

 ocellated spots are entirely absent on the under side. 



Pisces — A specimen of the ten-spined stickleback, Gasterosteus 

 pungitius, a somewhat rare fish.

At the opening meeting of the Session on December 

 1st, 1910, a lecture with this title was given by the 

 Chairman. A condensation of the greater part of 

 this paper is printed on p. 99 ; the remainder con- 

 sisted in a more detailed explanation of the difference between the 

 two kinds of photography, each branch, portraiture, architecture, 

 landscape, etc., being considered in turn. The lecture was illustrated 

 by photographs from the current photographic journals, which were 

 handed round. 



On February nth, 1911, an extremely interesting 

 °°" r lecture on "Colour Photography" was given to 



grap y. w h a t was perhaps a record sectional audience (85) 

 by G. G. Hamilton, Esq., f.r.c.s. The lecturer gave an exposition
