I'm keen for a line of plain, full, roomy old-fashioned flannel nightgowns of the improved T. A. Buck Featherloom products variety.

我热衷于使用经过改进的 T. A. Buck Featherloom 产品系列的朴素、饱满、宽敞的老式法兰绒睡衣系列。

New and improved varieties will inevitably supplant and exterminate the older, less improved and intermediate varieties; and thus species are rendered to a large extent defined and distinct objects.

新品种和改良品种必然取代和淘汰老品种、改良品种和中间品种；因此，物种在很大程度上被渲染为定义明确的对象。
