That if what I ascert be fact and Ministers refuse to take the rational and easy means here pointed out of being rightly informed and my engines should be practiced to the Injury of the commerce and fleets of England the people will not Suffer in silence but attach the whole blame to Ministers for wilfull neglect, therefore in as much as gentlemen regard their future reputation this Subject is of serious consequence to them. _Second._ If the Engines be harmless it certainly is important to be convinced on this head But will Ministers consent to be convinced on Vague reports and Vulgar opinions which accompany all new Inventions and not calmly sit down with nautical men and by examining principles penetrate into facts—? My Lord men of sense must penetrate into all the facts connected with this subject and that His Majesty’s Ministers may not have the least excuse, that they have not had a fair and timely warning on what maybe the consequence of these inventions I have Written this letter which I beg your Lordship to Communicate to His Majesty’s ministers. In case of a Committe of investigation I conceive the principle points for consideration and to guard the interest of the nation will be as follows, _First_ What is the present state of perfection of submarine navigation and attack,? _Second_, To what state of perfection is it capable of being brought _Third_ With such engines in the hands of an Enemy could they injure the commerce fleets and independence of England? _Fourth_ What is the general opinion of this subject and public knowledge of it,? _Fifth_ Under all considerations is it policy to practice such engines or to let them be practiced,? _Sixth_ Is it the interest of the nation that they should rest in their present state and is the public or European mind so little impressed with the use of Such engines that they may rest in their present state of incertitude?
