know scientifically of our species and forms of Vttis is directly due 

 to Dr. Engehnann's investigations. His first separate publication 

 upon them, "The Grape Vines of Missouri," was published in 18G0; 

 his last, a re-elaboration of the American species, with figures of their 

 seeds, is in the third edition of the Bushberg Catalogue, published 

 only a few months ago. 



Imperfect as this mere sketch of Dr. Engelmaiin's botanical author- 

 ship must needs be, it may show how much may be done for science in 

 a busy physician's horce suhsecivce, and in his occasional vacations. 

 Not very many of those who could devote their whole time to botany 

 have accomplished as much. It need not be said, and yet perhaps it 

 should not pass unrecorded, that Dr. Engelmanu was appreciated by 

 his fellow botanists both at home and abroad, that his name is upon 

 the rolls of most of the societies devoted to the investigation of nature, 

 that he was " everywhere the recognized authority in those depart- 

 ments of his favorite science which had most interested him," and that, 

 personally one of the most affable and kindly of men, he was as much 

 beloved as respected by those who knew him. 



More than fifty years ago his oldest associates in this country — one 

 of them his survivor — dedicated to him a monotypical genus of plants, 

 a native of the plains over whose borders the young immigrant on iiis 

 arrival wandered solitary and disheartened. Since then the name of 

 Engelmann has, by his own researches and authorship, become un- 

 alterably associated with the Buffalo-grass of the plains, the noblest 

 Conifers of the Rocky Mountains, the most stately Cactus in the world 

 and with most of the associated species, as well as with many othir 

 plants of which perhaps only the annals of botany may take account. 

 It has been well said by a congenial biographer, that " the Western 

 plains will still be bright with the yellow rays of Engelmannia, and 

 that the splendid Spruce, the fairest of them all, which bears the name 

 of Engelmann, will still, it is to be hoped, cover with noble forests 

 the highest slopes of the Rocky Mountains, recalling to men, as long 

 as the study of trees occupies their thoughts, the memory of a pure, 

 ui right, and laborious life." 



ARNOLD GUYOT. 



Arnold Gutot, Ph.D., LL. D., was born near Xeufchrvtel, Swit- 

 zerland, September 28, 1807. His earlier studies were pursued at 

 Neutchritel, Stuttgart, and Carlsruhe. In his delightful memoir of his 

 friend Agassiz, prepared for the National Academy, he gives a beau-
