Thanks to the fact that nowadays more and more books are digitized we are able to read books that are some times for decades no longer available for the public for several reasons. That's quite a pity while these books contains useful information while the archives are destroyed, incomplete or nor accessible. In this specific magazine was an article titled “The National Defence Madness” published in which the British navy was compared with several other navies and the results were presented in the British Parliament.
P. 361: “The following is the navy of Portugal: 2 ships of 80 guns, 5 frigates of 50, 1 of 54; 8 corvettes from 20 to 24, 11 brigs of 10 to 20, 7 schooners, and 2 steamships.”
