an organization for the advancement of science in the young 
metropolis. He was one of the original seven, and the last 
survivor of them, who, in April, 1854, organized the Califor- 
nia Academy of Sciences; and from that time to the end of 
his life he was actively connected with it. To him the Acad- 
emy is indebted for the early beginnings of its herbarium and 
botanical library. He took occasional trips into various parts 
of the State, collecting, making drawings of plants new or rare, 
and publishing a few species in the Proceedings of the Acad- 
emy; also contributing more or less to the horticultural and 
agrieultural departments of several of the early papers and 
magazines that were published in San Francisco. In 1867 he 
was appointed surgeon and botanist to an expedition which, 
under charge of Professor Davidson of the U. S. Coast Survey, 
made asummer's exploration of the shores of Alaska and 
some of the neighboring islands. The botanical collection 
nambered, I think, several hundred species. The specimens 
were good ; butonly three sets were made, one of which went 
to the Smithsonian Institution, another to the herbarium of the 
Philadelphia Academy, the third being given to the Califor- 
nia Academy. Two or three years later, being again with the 
Coast Survey party, he was on the island of Santa Cruz, but it 
was in the month of November, when little botanizing could be 
done, and only a few fragments in the way of specimens were 
secured and brought home from this island which has since 
proven a field of such unusual interest; but all these fragments 
represented species then new to science, although he did not 
recognize more than one of them as such ; the others having 
been since published, and still more recently collected again 
. by the present writer. 
Dr. Kellogg would not have elaimed for himself the place 
of a scientifie botanist, nor have wished others to elaim it for 
him. He had a great love for all forms of plant life, more 
partieularly of trees; and he had a keen eye for detecting 
varietal and specific differences. He was fond of sketching 
them and writing-about them; and when writing upon a species 
which he thought new to science (and, in his earlier years
