The _P_ and _M_ are all of the same general type. Principal features of these ships, which were designed by Captains Crocci and Ricaldoni, are the shape of the envelope, (maximum diameter very far forward), keel and the box kite tail. The _Citta di Milano_ (semi-rigid) is an enlarged _Leonardo da Vinci_ (which see). _Special feature_ is the keel built into the envelope. This serves as a nacelle. Building.--One _Parseval_ (P.L. 15) about the same size as the other (P.L. 17), which was completed first. ~Army Dirigible Pilots.~ Agostoni, Capt. Biffi, Ten. Bosio, Ten. Crocco, Capt. G.
