V~. G. BLACK (Edinburgh) said meteorologisti might work to obtain results by laboured exactitude, but it was his desire to get and retail to others information about the climate of the different places. He did not pretend to have contributed a scientific paper. The instruments he used were not verified at Kew, nor set up in an observatory. The objection might be raised to some of them that they were of small calibre, but they had to be carried in a hand bag and he used the same instruments

... ghout. With regard to the evaporation, he could not carry a proper scientific instrument with him, such as one could get in an observator~, but was satisfied with a portable one ; and the same instruments being used throughout, the results might be used comparatively without great error. The evaporation at sea-side places was greater than he expected. It was in consequence of the amount of wind and sun. He thought the sea was as much a point of the meteorology of the sea-side as the air; and visitors to the sea-side enjoyed it as much as the air. He had made many observations of the waves. He had counted the number per minute, and he had noticed there were two sets of waves, the one set fit to bathe in, and the other unfit. He had also estimated their length and height. The waves came in on the surface of the sea driven by the wind, and having to recede in natural sequence were returned at great force owing to the decline of the beach below. Bathing in the upper waves would be safe, but if a person, were caught in the under current he would be sure to be drowned, and carried away like a stone. The retiring waves were highly dangerous.
