" A lar^e amount of work has been done by Mj". 

 •lohnstone on board the steamer on the above subject. It 

 is proposed to carry this on, but a Report is bein*,'- 

 prepared. This is work which can best be done on board 

 the steamer, but when a scientist is not on board parcels 

 of fish might be sent to Liverpool or Piel. Inedible iishes 

 are also desired. Large ray and skate should be examined, 

 but this can obviously only be done on board the steamer.

" If it is proposed to provide the steamer with a hydro- 

 graphic research equipment (water bottle for collecting 

 samples of water from the bottom or from intermediate 

 depths, thermometers, &c., at a cost of about £25j, and 

 the necessar}^ equipment for analysis ashore, then the 

 following scheme might be adopted : — 



" A collection of water samples, with exact observa- 

 tions of the temperature of the water at the surface, 

 bottom, or intermediate depths, should be made quarterly 

 along the f olloAviug lines : — 



"1. Fleetwood to the Skerries ; 



" 2. Bardsej^ Island to New Qua}- ; 



" o. Holyhead Harbour to Calf of Man ; 



" 4. Mull of Galloway to Point of Ayre ; 



" 5. Eamsey Bay to Fleetwood. 



This would take one week every three mouths ; and several 



of the lines might be combined with the periodical 



inspection of the Manx territorial waters. 



" Samples of water would be examined for salinity 

 ashore.'' 



Some of these subjects require no further explanation 

 as the}' have been before the Committee in the past, the 

 marked fish experiment is discussed above, and the others 

 are all in progress with the exception of the hydro- 

 graphical work whicli has not yet been started.
