High collars worn by youths keep the head at the wrong angle, and also perpetuate the deformity of the jaw which is caused by breathing through the mouth. They also prevent the shoulders from being squared in the attempt to get rid of round shoulders. Dr. Cantlie urges a return to the brace worn by our fathers, and still occasionally seen, in which the straps are not united. It is impossible for any one wearing joined braces to stand erect with the shoulders squared, for they press on the neck and cause the wearer to poke his head forward. Dr. Cantlie, however, hopes that the difficulties in the way of obtaining separate braces will not lead to the adoption of the elastic belt, for the only place where this could be worn without bad effects is below the haunch bones, and in ordinary dress this would bring it below the waistcoat. It will be found also that the use of belts by labourers brings evils in its train which were not mentioned by Mr. Heather Bigg, when speaking of the advantages of girding up the loins. (See page 329.) No account of dress and its developments would be complete without a reference to Mrs. Bloomer and the garments which now bear her name, and are emblematical of rational costume. That women have no absolute claim to petticoats as their own special dress has been made quite clear, and it is equally evident that in many places they wear trousers as a matter of course. Still, in this country there seems to be a rooted objection on the part of the majority to doffing skirts, though this seems, however, to be growing less day by day, in spite of the many reasons which cause the fair sex to cling to petticoats. As we have found before, garments which fall to the ground give dignity, and women sacrifice their dignity with difficulty. Yet, as need hardly be pointed out, men do not wear dressing-gowns when they are jumping, nor fur-trimmed mantles when they go to business. Dresses with trains could be kept for ceremonial occasions, or when there is nothing much to be done, or again, we might add, when there is little dust to be raised.

Putnam's Sons).] Bacteriology has shown us that the long skirt disseminates germs as it trails along the ground; in fact, it stirs them up for other people to breathe, and the culprit herself carries off as her fair share a large quantity which settles on her dress. In this way the germs of disease are carried home to the dwelling-house. In these days also, when women even jump on and off motor omnibuses before they are at a stand-still, it is evident that long frocks are objectionable and dangerous.
