MARINE BIOLOGICAL STATION 229 



a single page is kept for the details, including bodily measurements, external characters, 

 etc., of each foetus. 



Laboratory work in connection with the work at the whaling station (apart from the 

 examination and analysis of the log-book data) consists in the detailed examination of 

 such specimens as ovaries and foetuses, routine section cutting of pieces of testis, 

 mammary gland and other tissues, and the examination of parasites, etc. 



In the hydrological work undertaken at the Biological Station water samples from 

 the ships were analj'sed for salinity and phosphate content, and occasionally for oxygen 

 content. The methods used in this work are indicated on p. 213. In addition to the 

 usual equipment required for work of this kind it is necessary to have an apparatus for 

 the preparation of fairly large quantities of distilled water. It is also advisable to have 

 a good supply of spare beakers, flasks and other glass ware. The chemical equipment 

 of the laboratory includes apparatus for various other investigations to be carried out 

 as opportunity arises : among these are the determination of the oil content of blubber 

 and the analysis of whale's milk. 



Work on the fauna of South Georgia consisted in shore collecting, trawling, plankton 

 and hydrological work in East Cumberland Bay and some investigation of the local 

 birds and seals. The gear most frequently used in Cumberland Bay has been an 8 ft. 

 beam trawl towed from the launch, but owing to the great depth of the water (largely 

 from 50 to 100 fathoms) this can only be used close to the shore. The fauna of Cumber- 

 land Bay, however, is very rich, and many interesting specimens may be obtained in 

 this way. A small dredge was occasionally used, but better results were obtained with 

 the beam trawl. The launch was fitted with a winder carrying 100 m. of 4 mm. wire, 

 a small davit and a recording sheave. This outfit was used both for sounding and for 

 working water bottles and vertical nets.
