tively few, disappears when we consider that by being admitted they would not be made better off, for more than a short time; the only permanent effect which their admission would produce, would be to lower the others to their own level. To what extent the force of this consideration is annulled when a tendency commences towards diminished over-crowding in the labouring classes generally, and what grounds of a different nature there may be for regarding the existence of trade combinations as rather to be desired than deprecated, will be considered in a subsequent chapter of this work, with the subject of Combination Laws.

Such are the fees or charges of professional persons: of physicians, surgeons, barristers, and even attorneys. These, as a general rule, do not vary, and though competition operates upon those classes as much as upon any others, it is by dividing the business, not, in general, by diminishing the rate at which it is paid. The cause of this, perhaps, has been the prevalence of an opinion that such persons are more trustworthy if paid highly in proportion to the work they perform; insomuch that if a lawyer or a physician offered his services at less than the ordinary rate, instead of gaining more practice, he would probably lose that which he already had.

They do this, not merely from ostentation, but also from more reasonable motives; either because they desire that those they employ should serve them cheerfully, and be
