and should a fault be discovered a simple process of reversal of 

 ship and machinery brings home the faulty portion. 



Another great point is to keep the vessel trimmed and steady. 

 For the former requirement nine separate water-tight compart- 

 ments, including the cone in each tank, which also is hollow, are 

 provided, so that water may be admitted as the tanks are emptied 

 of cable, and thus the ship is kept trimmed. To ensure steadiness 

 and avoid the rolling to which telegraph ships are subject, two 

 bilge keels are set on at an angle of 45 ; this was done at the 

 suggestion of Mr. Win. Froude, whom, said the speaker, " I have 

 to thank for valuable advice and assistance on several new points, 

 connected with the ' Faraday.' " 



A steam-launch is carried on deck, whence she can be lowered 

 into the water with steam up, ready to land shore ends and perform 

 ether useful operations. 



Another class of work for which the vessel is fitted is " grap- 

 pling " for lost or faulty cable. In shallow seas this is a very 

 simple operation, but in deep water it is rather a delicate matter, 

 and requires the co-operation of two or even three vessels, so as to 

 lift the cable without forming an acute angle, and thus to lessen 

 the chance of fracture. A special rope, made of steel wire and 

 hemp and of great strength, is provided for this work. Some 

 specimens shown could bear strains up to 16 tons. 



In conclusion, the speaker adverted to the late Professor Fara- 

 day, . noticing the great services he had rendered to electrical 

 science, his singleness of purpose, and the invariable kindness 

 with which he had encouraged younger labourers in the same field. 

 The friendly encouragement which he himself had experienced 

 from him would ever remain a most pleasing remembrance. He 

 had seized with delight on the present opportunity to pay a tribute 

 to the honoured name of Faraday, and was happy to be able to do 

 this with the full consent of the revered lady who had stood by the 

 philosopher's side for forty years, while labouring under this very 

 roof for the advancement of knowledge. The name of the vessel 

 and her mission in the service of Science would combine, he 

 thought, to create an interest in her favour in the minds of the 

 members of the Royal Institution, and he hoped that on the morrow 

 she would put to sea accompanied by the earnest wish, " God speed 

 the ' Faraday.' "
