By way of example and without limitation
show examples, go forever , nothing can stop you -- 加拿大人
"By way of example" is used to introduce something you are about to do or say that backs up or helps to explain a previous claim
The express is certainly old fashioned if not completely out-of-date. In current speech and writing you would simply say, "For example."
This is just one example, it's not the only possibility, and therefore mentioning this example is not intended to limit other examples which are, perhaps, different in nature. There is no implied restriction on the range of other, possible forms of powers."
