had constructed ten years ago, for Transfusion of Blood, &c. ; 

 and stated that he had had occasion to use it recently, and had 

 found it very useful for the purpose. 



The Secretary then read Mr. M' Andrew's paper on 

 Marine Dredging. 



" On Marine Dredging, with notes and observations, the result of 

 personal experience during the summers of 1846 and 1847. 



" Having been occupied during the past and preceding sum- 

 mers in examining, by means of the dredge, the sea bottom 

 adjoining our coasts, in fulfilment of my duty as a member of 

 the Dredging Committee of the British Association, and with 

 the view of adding to the imperfect knowledge which we possess 

 of the invertebrate inhabitants of the deep ; it is my intention, 

 on the present occasion, to state some of the more interesting 

 results, with such remarks and observations as they suggest ; 

 but without entering upon a narrative of my operations during 

 the various expeditions I have undertaken, or the numerous 

 difficulties, and even danger, with which these have been 

 attended. It may easily be imagined, that to bring up from 

 their quiet habitation the dwellers at a depth of 500 feet 

 and upwards, wliile exposed to the heavy swell of the Atlantic, 

 in northern latitudes, where the weather is seldom fine and 

 settled, can be no child's play. 



" My researches have been principally directed to deep 

 water, at a distance from land, in preference to inlets and shel- 

 tered situations, because, in consequence of these last affording 

 abundant results of comparatively easy attainment, there are 

 not wanting others who are willing to explore them ; whereas, 

 few or none appear to combine the means with the inclination 

 for the more arduous service. I may be allowed to add, that 

 any sacrifice I may have made in the pursuit of knowledge has 

 been abundantly compensated by the manner in which my 

 labours have been appreciated by many of the most eminent 

 friends of science.
