THE MICROSCOPE. 9 
. It was here, in the laboratory of Dr. Thomas Dwight, now 
Parkman professor of anatomy at Harvard, that the subject of our 
sketch first made the acquaintance -of the microscope, and com- 
menced the practical study of microscopy, devoting much of his 
time for nine months in the year to human and comparative anat- 
omy. It was at this time that-he became acquainted and was brought 
into daily contact with the lamented Robert Tolles, and from the 
intimacy thus formed came a friendship which lasted until the 
death of this incomparable lens maker. Mr. Tolles took a great 
interest in young Lewis, and embraced every opportunity of giving 
him instruction in the optics of the microscope and the methods of 
using lenses to the best advantage. 
In 1876 young Lewis left Harvard and entered the College of 
Physicians and Surgeons, New York, being attracted thither by the 
superior clinical advantages which it offered. Here his microscopi- 
cal studies were continued under Professor Delafield. He was grad- 
uated from the College of Physicians and Surgeons in 1878, but 
remained in New York for a year longer, taking special courses in 
the hospitals of that city. 
It was in Albany that Dr. Lewis commenced the private prac- 
tice of medicine, having the good fortune to effect a partnership 
with Dr. W. H. Barclay, an old and well-known practitioner, whose 
daughter he subsequently married, December 10, 1879. In 1879 
Dr. Lewis went to Europe, “put in” a couple of years in the 
laboratories of Vienna and Heidelberg ( Berlin had not then become 
so famous) and returned home in 1881, to finally settle down to fight 
the battle of life in earnest. He was offered and accepted the 
position of consulting surgeon to the Travelers’ Insurance Co., of 
Hartford, which office he now occupies. 
Already having a “bent” in that direction, the entrance of Dr. 
Lewis into this position determined him to devote himself 
to medical jurisprudence, and it is in this direction that his 
microscopical work has been almost exclusively directed. Having 
an excellent laboratory, fitted up with the very best instruments that 
could be purchased, with facilities for experimenting in photography 
and electrical science, he has devoted a large proportion of his time 
to the application of electricity to photomicrography and has done 
some valuable work in that direction. 
At Rochester, in 1884, Dr. Lewis read a paper on “ Hair, Micro- 
scopically Examined and Medico-Legally Considered,” and in the 
working sessions exhibited his microscope and electrical apparatus, 
to illustrate his method of using electricity in microscopical work.
