hurried on to new fields, and made no drawings to illustrate his conclusions. As 

 embryological notes must be in pictorial form, most of his work is unrecorded 

 and as his thesis is his single complete and illustrated work, it has seemed proper to 

 his instructors, pupils and friends, to publish it. Although he himself would 

 have wished to include his later results, this is now impossible, and it is here printed 

 exactly as he wrote it in the winter of 1875-6. 



In the summer of 1876 he made, conjointly with myself, a study of the embryology 

 of Limulus. This was very complete as regards the early stages, and we had intended 

 before publishing, to spend one or two years more upon it, and to make it an 

 exhaustive account of the entire embryology and anatomy of Limulus, but the publi- 

 cation of Kingsley's fully illustrated paper upon the later stages of development, 

 and my own employment with other subjects, and Dr. Bruce's desire to study other 

 forms for comparison, retarded the completion of the work. 



The segmentation of the egg, the formation of the blastoderm and of the germ- 

 layers, and the anatomy of the young larva, were all thoroughly studied, and illus- 

 trated by nearly a hundred drawings, and I hope that some means of publication 

 will soon be found. 



Upon these two papers Bruce's reputation among strangers, as a student of 

 nature, must rest, but all who knew him personally will feel how very inadequately 

 this will represent what a few years more might have produced. 



As soon as the news of Bruce's death was received in Baltimore a large number 

 of his friends and pupils met in the biological lecture room of the University to take 

 action indicating their grief at his death and their sympathy with his relatives. 



On motion of Dr. Howell, Professor Martin took the chair ; he requested 

 Mr. Washburn to act as secretary. 



Professor Martin said : "My friends, the University has not existed for its brief 

 ten years, without the hand of death showing its power among us. Those who 

 have gone have been of almost every degree of academic dignity, from professor to 

 undergraduate. We sorrow when the old man dies, but we know that he has lived 

 to do his work and make his name and fame. We grieve when the bright lad dies, 

 but we know that he has been spared years of toil and struggle. Surely no death 

 is so sad as that of a young man, who has just completed seven or eight years of 

 hard work at college and university, and is beginning to enjoy the fruits of his 

 labors. Such was the death which is the occasion of this meeting.
