CLA.RENDON at the Foreign Office. The safety, however, and welfare of the country would be endangered if the portfolio passed from the vigoeous hands of the f 'ruler Minister to one so weak and inefficient as his successor, "Pecially at a time when such imp )rtant questions were pending with he French and Neapolitan Governments. Such was the tenor of the sundry Jeremiads by Close who wished to constitute Lord PALMERSTON perpetual dictator, encouraging him to treat with  contumely and insult every member who dared to give expression to opinions opposed to his own. We have now witnessed the satisfactory termination of • the untoward differences with the Cabinet of Paris, and certainly the publication of the correspondence respecting " The Cagliari," on which we commented on Monday, dues not place the loss to the country from the resignation of Lord CLARENDON in quite so striking a light as the panegyrists of that Nobleman would wish it to be regarded in. Nothing indeed more humiliating to the national dignity can be conceived than the correspondence and entire proceedings up to the time of the change of Government. And there are few consistent Liberals who would not now regard the return of the Earl of CLARENDON to the Foreign-office as a matter that would inevitably follow the overthrow of the DERBY Cabinet.  He it was who not merely omitted answering, but excused and justified the despatch of Count WALEWSKI, and thus caused the exclusion from office of the Ministry of which he was an influential member. He, too, was the person who so seriously compromised the national dignity by his milk and water remonstrances on the outrageous cruelty exhibited in reference to two British engineers, virtually conniving at that cruelty, until one of the victims (WATT) was driven to attempt suicide, his intellects having been affected by his protracted incarceration ; and the bodily health of the other (PARK) had yielded to his protracted sufferings. Already, WATT has been restored to his country, although but a mere wreck, while the other has been liberated from confinement and given a fair chance of recovering his health. A decided and energetic tone has also been adopted, calculated to bring King BOND/ and his advisers to a due sense of the folly of which they were guilty, in striving to gratify their vindictive feelings against Great Britain, at the Expense of two innocent Englishmen, illegally captured out of the Neapolitan waters, and treated as if they had been malefactors of the worst elms.  We have already contrasted the legal opinions given by the late law officers of the Crown with the lucid and convincing document signed by Dr. TRATERS Twiss. In the former there was a manifest desire to avoid the responsibility of making any demand, which, if refused, might be followed by hostilities. For that purpose, assumptions totally unwarranted by the facts were put forward—assumptions which were not warranted, or even ventured on by Commander CARAFA himself. The benefit of the doubt was given to the Sicilian authorities, and a justification put forward on utterly untenable grounds, which were not alluded to by the parties implicated. Dr. Twiss, on the contrary (as well as Dr. PRILLIMORE), clearly and unequivocally examined every circumstrance, and proved the total illegality of the entire proceedings ab initlo. And yet Signor CARAFA, depending on the weak and vacillating tone of Lord CLARENDON, declares that England herself has declared " that there cau be no right to require anything more than a speedy, regular, and public trial." This was his impression from Lord CLARENDON'S diluted correspondence. He was, however, undeceived by Lord MALMESBURY, who expressly stated, that her Majesty's Government " cannot admit that the prima facie evidence which was produced, as far as it is at present known, could justify the prolonged confinement to which these British subjects have been exposed, and from which they have SO severely suffered," emphatically adding, " Her MAJESTY'S Government still believe that the Engineers, WATT and PAux, were entirely ignorant of the conspiracy to BOiZ3 the Cagliari, and were throughout acting under durance."  From the above, it is manifest that Lord MALMESBURY, in a few days, effacted, through Mr. LYONS, what Lord CLIRENDON COM pletely failed in doing during as many months. The vigour and energy so clearly demonstrated proved to the Neapolitan Government that they could no longer maintain the contumelious trifling displayed towards the late Foreign Minister. And we hope and believe that the demand for compensation to the sufferers as atonement to the Government will be responded to with equal promptitude. Lord MALMESBURY has shown that the old proverb, " where there's a will there's a way," is  applicable to diplomacy, as well as other matters
