698 POPULAR SCIENCE MONTH LF. 



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 descrip- 

 tions 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 ex- 

 amined 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 com- 

 parative 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 Advance- 

 ment of Science, President of the American Microscopical Socie- 

 ty, and President of the United States Hay Fever Association. 

 His latest contribution to the Manual of the last-named associa- 

 tion was an article on The Comparative Hygiene of the Atmos- 

 phere 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 studj^ 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
