water plants, they all need considerable water to enable them 

 to thrive, and so are always found in wet places. 



Owing to their freedom of motion they were at one time 

 supposed to be animals. Now it is known they are plants, as 

 they can perform all the functions of plant*, and no animal, 

 with all his superiority, high nature, etc., is able to do this. 

 They are found everywhere in all inhabited countries, and in 

 fact all over the seas, so it may be readily granted that a plant 

 so common and wide-spread as this should be quite fjimiliar to 

 every one. 



Again, not only are the living plants so wide-spread and com- 

 mon, but the shells of the dead ones remain intact for many 

 years; and in some localities these tin}^ shells are so numerous 

 as to form a large portion of the soil. Some of the best known 

 of tbese localities are the sites of Richmond, Virginia, and Ber- 

 lin, in Germany. — Emily L. Gregory, in The Popular Science

NECROLOGY. 



Rev. Samuel Lockwood, Ph. D. — ^The frontispiece of our 

 March number contained a portrait of Dr. Lockwood, through 

 the kindness of Dr. Ward. He died at his home in Freehold, 

 N. J., on January 9th, 1894, at the age of 75 years. Born in 

 England and educated in New York, except for a theologicul 

 course in New Brunswick, N. J., he spent the years from 1850 

 to 1869 in pastoral work in various churches. In 1867 he un- 

 dertook the additional labor of Superintendent of Instruction 

 for Monmouth County, N. J., a field for which his tastes and 

 talents as an educator were so well adapted that three years later 

 he removed to Freehold, N. J., and devoted the remainder of 

 his long life to the work with an ability that gave him a na- 

 tional reputation. He became a biologist in the brondest sense, 

 his great faculty for both stud}' and teaching leading him out 

 freely in different directions. Microscopy, however, was his 

 favorite resource in every field. His valuable addresses and 

 other works were an important element in the life of the New 

 York Microscopical Society, and of the New Jersey State Mi- 

 croscopical Society, of which he was one of the founders and 

 chief supporters, and of which the minutes, lately i)ublished,
