Rh When this work first appeared, distinguished botanists abroad thought it either a waste of time or beneath their dignity to be engaged upon popular works; but of late years we find that the most eminent of them are putting out their "Hand-books" and "Popular Floras."

As highly as we value the "Text-Book," we think that in books of this character his "First Lessons" is not only a superior work, but the best work upon elementary science of any kind that we are acquainted with. It is indeed a wonderful attempt at popularizing science. What are considered abstruse points in physiology are told with such a matter-of-fact simplicity, that the reader is charmed as with a tale, and, after reading it, is in possession of more of the philosophy of botany than he could obtain from a dozen more pretentious volumes. We can only just allude to his charming works for young people, "How Plants Grow" and "How Plants Behave," works which, though written for children, will be found to contain bits of wisdom for older heads.

The work that we have indicated implies a great amount of labor, and Dr. Gray is essentially a worker. No mechanic goes to his daily task more faithfully or continues at it with more assiduity than he. Very few, who are not familiar with the laboratories and studios of scientific men, have any idea of the amount of labor performed in them. Their work is by the many looked upon as a sort of half play, not to be compared, in its demand upon the physical and mental resources, with the daily task of the book-keeper or cashier. There are not many who work harder than Dr. Gray, but, when work is over, few more keenly enjoy the relaxation. One of [sic] our pleasantest recollections of him is seeing him, after a hard day's work, engaged in a rough-and-tumble frolic with an enormous Newfoundlander.

It is supposed by many that a student's life diminishes bodily vigor. We can name several striking illustrations to the contrary, and eminent among them is the subject of our sketch. We have not tried a walk with him for several years, but we venture to say that few young men of twenty could take an afternoon's tramp with him and not feel a sense of relief when the excursion was ended.

Outside of the domain of botany, Prof. Gray's contributions to literature are not a few, but, as these were contributed to the North American Review and other magazines anonymously, their authorship is not known outside of a small circle. Some of his reviews are remarkable specimens of acute criticism, in which the subject could forget the sharpness with which he was flayed, in admiration at the dexterity of the operator. The estimation in which Dr. Gray is held by his scientific compeers is attested by the fact that he has for several years been the president of that distinguished body of scientists, The American Academy of Arts and Sciences, and is for the current year the president of the American Association for the Advancement of Science.
