The course of study led him at last to Botany, to which he gave 

 himself wholly at the time as was his Avout with every scientific pur- 

 suit. Prof. Agassiz's friendship and direction had enlisted his inter- 

 est in Zoology, as a science. Dr. Gray now extended the friendly 

 hand. Soon discerning merit, the last named gentleman took him 

 under his especial training. From this time — Eureka! the line of 

 work was found. The success of the labor proves the justness of the 

 final decision. He learned to love the science, not only for itself but 

 for the great teacher. 



It was by Dr. Gray's advice that he visited tlie Hawaiian Islands, in 

 company with Mr. Wm. T. Brigham. The expedition was not only 

 fruitful to himself, but to his favorite science, for such it became, 

 although he ever regarded it as but one limb of that study of Geology 

 which was to tear the secrets of time from the bosom of the earth. 



Of this expedition let his companion, Mr. Brigham, tell. 



"When Dr. Asa Gray was told I was soon to visit the Hawaiian 

 Islands he asked me to collect the very peculiar flora of that group, 

 and suggested the propriety of asking Horace Mann to accompany me. 

 It was a short notice, but his friends advised him to go, and he joined 

 me in California. From that time, for more than a year, we were con- 

 stant companions, and many a long ride, many a weary walk did we 

 share. For more than six months we kept house together in Hono- 

 lulu, and from the first day to the last he was the same modest, retir- 

 ing, hard-working, unselfish, conscientious man. Thoroughly alive to 

 all the beauties and wonders of nature there surrounding him he often 

 wrote home that he enjoyed every moment; and often, indeed, have I 

 seen him in perfect ecstasy over the discovery of some new plant 

 after a hard climb up some island precipice." 



"As the result of our Hawaiian explorations, five new genera were 

 added to the flora, one of which was dedicated to him under the name 

 of Hespeuo.maxxia, and has been engraved for the next part of our 

 Memoirs (Boston Society of Natural Histoiy) while of new species 

 of flowering plants no less than seventy-one, or more than eleven per 

 cent, of the entire Phsenogamous Hawaiian Flora were discovered. 

 His published works, besides a number of reviews in the American 

 Naturalist (one of which was written a short time before his death), 

 were: — On some Haioaiian Crania and Bones. — Proc. Bost. Soc. Nat.
