scientific societies; but so far as we know, they have no common bond of union. Seeing that there is already an efficient American Association, we should not advocate the formation of a separate Canadian body; but possibly the Montreal meeting might be able to do something to federalise the separate Canadian societies. We suggested some years ago that the Association might do such a service to the numerous local societies in this country, and we are glad to know that the suggestion has borne fruit, and that already a real advance has been made in this direction. But whatever may be the results of the Montreal meeting, it is clear from the programme which has been drawn up that everything possible is being done to render the occasion one of genuine enjoyment to all who are fortunate enough to be present. The Canadian Parliament has voted so handsome a sum for the entertainment of the Association that its expenses are likely to be less than at an ordinary meeting. Provision has been made for free passages and free living for fifty of the officials, who need not spend a penny from the time they set foot upon the steamer until they step ashore again upon their native land. Not only so, but a sum of $14,000 has been allotted for the reduction of members' passages to Canada in addition to any abatement of fares allowed by the steamship companies. The most important of these companies, sailing not only to Quebec and Montreal, but to New York and Newport, offer reductions averaging about 10 per, cent, on the ordinary fares. The companies who offer these advantages are the Allan, the Dominion, the Beaver, White Star, Cunard, National, Anchor, Guion, Inman, Monarch, and Union lines; so that intending visitors have ample choice of route. On the other side, again, all the railway companies have shown the greatest liberality. The Government railways are free to all who produce members' vouchers. The Canada Pacific Line will from July 1 up to the date of the departure of the special free excursion to the Rocky Mountains, grant to visiting members free passes over its lines to the northward (Rocky Mountains, Lake Superior, &c.) and intermediate points. This company also offers to one hundred and fifty members of the Association a free special excursion to the Rocky Mountains, by way of Georgian Bay, Thursday Bay, and Winnipeg, providing that those places passed during the night on the outward journey will be repassed during the day on the return. The only thing members will have to pay for will be meals, which will be provided at a rate not exceeding 2s. Arrangements, moreover, will be made for trips and excursions from Toronto, across Lake Ontario to Niagara, under the direction of local committees to be formed in both places, giving to all members an opportunity of visiting the Falls. Various other excursions have been liberally arranged for by the company, so that visitors will have ample opportunity of seeing most that is worth seeing in Canada for
