I can't tell the difference between margarine and butter.

我无法区分人和黄。

Butterine and oleomargarine, which must be labelled as such, if of good quality, are nutritious, inexpensive fats to be used in place of creamery butter.

人和人黄质量好的，成份高价格低的脂，可代替乳炼黄。

Other examples are: the fat of meats, bone-marrow, suet (the best found around the loin and kidneys of the beef creature), cocoanut butter, butterine, and oleomargarine.

肉类脂肪、骨髓、板（牛腰板处最好的脂），可可豆、黄、人、人黄。
