POPULAR SCIENCE MONTHLY.

In his studies in fishes, besides some abstruse problems which he attacked, not always with equal success, Dr. Lockwood gave a charming lecture on sticklebacks, which included some descriptions of their nesting and the raising of their young. He also made some discoveries among the mollusks. But perhaps his most extended labor was devoted to the oyster, as is shown in his report published by the State of New Jersey. Upon this subject as a lecturer and writer he won great applause and enduring fame. An amusing incident, which was at the same time a compliment, occurred some years ago when Dr. Lockwood was lecturing on The Life of an Oyster. Two oystermen, at the conclusion of the lecture, got into audible discussion over what they had heard. Said one to the other, "I tell you, Ned, he knows it all, from the cedar on Lebanon down to soft clams!"

Dr. Lockwood's studies were not confined to fishes, but he examined and investigated zoology generally. There is also a third phase in his scientific character which must not be omitted. His discovery of the fossil plants in New York led him into the study of living plants; hence he was not without reputation as a comparative botanist. He seemed to see all things as a unit—nothing unrelated—Nature as the oneness of the Infinite Maker. His knowledge of these several fields, which was sharply defined and comprehensive, and his simple yet almost poetic generalization, made everything from his pen attractive to the popular reader.

But back of all was a devout mind, with an overflowing love of any and every living form, animal or plant. In his study his aquarium was always. an attractive object to visitors. He even had a little froggery, where different species of frogs enjoyed themselves. Snakes and lizards, too, entered into his friendship, and afforded him opportunity for the study of their habits. Then, with all these, there seemed to be a pathological instinct in the good man's heart. As a microscopist he investigated the diseases of fishes and of plants.

He was fellow of the American Association for the Advancement of Science, President of the American Microscopical Society, and President of the United States Hay Fever Association. His latest contribution to the Manual of the last-named association was an article on The Comparative Hygiene of the Atmosphere in Relation to Hay Fever. An article of similar character was reproduced, together with the plate from the original, abroad, where Dr. Lockwood was well known among scientists, and was an honorary member of the Belgian Microscopical Society.

Speaking of his aquarium, the writer on one occasion observed in a north room of his study several small aquaria, which were the quarantines to which he intrusted the sick animals while making every effort to save them. These aquaria seemed to be
