at Wurzburg, in Bavaria. His exile, however, 
did not last very long, for as far back as 1856 
he was elected professor of pathological anat- 
omy in Berlin, an appointment which he still 
retains. On account of Professor Virchow’s 
infirm state of health the jubilee proceedings 
were of a more private character than would 
have otherwise been the case, being limited to 
addresses of congratulation delivered by the 
rector of the University and the dean and pro- 
fessor of the medical faculty. The rector, 
Professor Schmoller, referred to Professor Vir- 
chow’s achievements not only as a physician 
and a pathologist, but also as a_ biologist 
and as a savant whose methods of research 
had influenced every branch of human knowl- 
edge. The dean, Professor Huebner, eulo- 
gized him as a privat-docent of an altogether 
superior order—a teacher not only of students, 
but also of professors. At an age when young 
men were, as a rule, far from having mastered 
what had been already discovered he succeeded 
in solving the most difficult problems of biology. 
’ Professor Virchow in his reply pointed out that 
he was happy in the knowledge that a body of 
men now existed in German universities strong 
enough not only to maintain the principles laid 
down by him, but also to continue the work in 
the light of modern developments. He felt 
that his work was done and that he was now 
entitled to retire from his academical position, 
especially after having succeeded in obtaining 
a promise from the government that a new and 
modern pathological institute and museum 
would be constructed after his designs. A great 
number of telegrams, letters and other marks 
of Professor Virchow’s great popularity were 
received by him during the day. 
Tue National Photographic Record Associa- 
tion of Great Britain, to which we have already 
called attention, have sent out a circular in 
which they state that well-wishers of the As- 
sociation, the subscription fee for which has 
been fixed at a small sum with the object of 
enlisting wide and general support. Photog- 
raphers and others can assist by contributing 
photographs (which must comply with the reg- 
ulations set forth in the by-laws), or by acting 
as honorary agents and collectors in their re- 
spective localities. The Council look for gen-

[N. 8. Vor. VI. No. 153. 
erous support from photographic and camera: 
clubs throughout the country, as well as from 
individual amateur photographers, who must 
now form a complete network of workers over: 
the whole British Islands. The Council also 
appeal to the large and important professional 
class of photographers for copies of rare and 
especially interesting pictures taken by them. 
From scientists, antiquarians and others assist- 
ance is desired in searching among the rich 
stores of old and neglected negatives taken in 
past years which are known to exist, the identi- 
fication of which gets more difficult as time 
passes, and also by using influence with their 
amateur photographic friends in inducing them 
to seize opportunities of recording passing 
events. Others may render valuable help by 
purchasing pictures from dealers and presenting 
them to the national collection, thus rescuing 
records which might otherwise be lost. In the 
course of the present jubilee year there must 
have been many thousands of photographs 
taken of local celebrations, which, if brought 
together, would form a most valuable chapter 
of national history, and it may be remarked in 
passing that it should be born in mind that a 
single picture of historical interest will always 
be acceptable. In conclusion, the Council wish 
it to be understood that there is no thought of 
competing or clashing with the excellent work 
of the same kind which is being so well done 
by the several county photographic survey as- 
sociations, such as those of Warwickshire, Wor- 
cestershire, Yorkshire, Cheshire, ete., in their 
commendable efforts to form local collections, 
but rather a hope is entertained that such useful 
work may be encouraged by loans being made 
from time to time from the national collection, 
before being deposited in the British Museum, 
of interesting pictures from other localities for 
the purposes of exhibition. 
The Botanical Gazette states that the Seaboard 
Air Line Railroad, which extends from Ports- 
mouth, Va., to Atlanta, Ga., has inaugurated a 
novel system of instruction of the communities 
along its territory. During the present season 
it has been holding one-day farmers’ institutes, 
all illustrative material and appliances and the 
force of instructors being transported from place 
to place in a train of cars especially fitted up
