Several schools of porpoises have been seen this month, presumably in pursuit of herring. To anyone who has seen these animals gambolling in front of a ship’s bows when travelling at her best, the ease with which they maintain their distance is a matter of surprise--always on the point of being run down, but ever ahead, snorting playfully as if in derision at the possibility of their being overtaken by their lumbering follower. Off the island of Anticosta, in the Gulf of St Lawrence--where these animals attain a size several times larger than those of our home waters, and are of a cream colour--I had an interesting view of their manner of suckling their young. I have seen it stated that the mother by muscular compression expels the nutritive fluid, which is absorbed by the young one as it floats to the surface. The operation appeared to me to be one of actual contact. The young one--which, by the way, is of a slatey-blue colour--snuggling as close as possible to the mother as she lay somewhat on her side on the surface, all the while exhibiting the tenderest solicitude for her offspring. Truly the one touch of nature which makes the whole world kin. It is surprising to learn the evolution these animals have undergone in order to accommodate themselves to their altered circumstances. Land-dwellers at one stage of the world’s history, but acquiring a taste for fish, they gradually became aquatic in their habits, dispensing with such portions of their anatomy as were no longer necessary, while developing others more appropriate to their new sphere of existence, till, like their big brother the whale, from being a four-footed animal they became quite fish like in appearance, even to the cultivation of a dorsal fin, though still possessing rudimentary traces of their former construction. Change is apparent on every hand in the plan of nature; ages were necessary for the evolution of our present day horse from his five toed ancestors; and after all it does not seem so very startling when the transformation is enacted before our very eyes in a few short stages, as in the case of the common frog, from the gill breathing tadpole to the lung breathing adult. More startling it is to learn that man himself was at one time a gill breather, and, as biologists affirm, still exhibits traces of gill clefts at one stage of his embryonic development. _MARCH 1902._
