AuGUST 27, 1897.] 
(6) Investigations concerning the ty- 
phoid and erysipelas serums, as well as va- 
rious other researches in all the fields of 
micro-biology, are being pursued by the 
Professor himself, as also by the assistants 
under his supervision. There are 6 assistants 
and nearly 10 ‘extra-ordentliche’ assistants. 
The studio for micro-photography has 
recently been built and is equipped with 
Zeiss’s complete apparatus. 
The library, though in its infancy, contains 
most of the works on infectious diseases, 
bacteriology and hygiene, and is supplied 
with the medical periodicals in the English, 
French, German, Italian and Japanese 
languages. JI take this opportunity of ac- 
knowledging the receipt of the following 
official publications from America: U. S. 
' Department of Agriculture, Bureau of Ani- 
mal Industry; Bulletins U. 8. Treasury De- 
partment, Marine Hospital Service, Health 
Reports, ete.; City of Brooklyn, Department 
of Health, Annual Report. We should be 
glad to receive more of the American pub- 
lications. 
(b) Practical Course in Bacteriology. 
The utility of the knowledge of micro-or- 
ganisms being admitted, it was deemed de- 
sirable to give a practical course of bacteri- 
ology for the benefits of the licentiates in 
medicine. The first course was given in 
March, 1894. The course is of three months’ 
duration and is conducted by Professor 
Kitasato, who gives a series of lectures on 
the pathogenic bacteria. The assistants 
take their turn and serve as demonstrators. 
The laboratory for instruction accommodates 
50 students and is provided with all neces- 
sary appliances. Over 200 physicians have 
gone through the course. It is with great 
pleasure that we mention in this connection 
that the American naval surgeon and an 
English naval surgeon have availed them- 
selves of the facilities of the Institute and 
have pursued their investigations for a con- 
siderable length of time.

(Il.) THE CLINICAL DEPARTMENT. 
The wards in all are capable of holding 
50 patients. The admission is limited to 
cases of contagious diseases (except cholera 
and smallpox). Diphtheria, tuberculosis, 
typhoid, tetanus and relapsing fever are 
the principal maladies on the list. I 
may mention in this connection that 180 
cases of leprosy have been treated in the 
out-patient department with the injection 
of ‘Leprine,’ and 4 cases of complete re- 
covery, beside several cases of improvement, 
have been reported. The diphtheria statis- 
tics show a mortality of 9,44%.

NINTH ANNUAL MEETING OF THE ASSOCIA- 
TION OF ECONOMIC ENTOMOLOGISTS, 
DETROIT, MICH., AUG. 12-13, 1897. 
Tue Association met in room 212, Cen- 
tral High School building, immediately fol- 
lowing the adjournment of Section F. 
Thirteen active members were present, to- 
gether with many visitors, prominent among 
the latter being Dr. C. A. Dohrn, Professor 
EH. B. Poulton and Dr. C.S. Minot. The 
attendance for the four sessions averaged 
about 35. The address of the retiring 
President, Professor F. M. Webster, Woos- 
ter, Ohio, treated of ‘The Present and the 
Future of Applied Economic Entomology 
in the United States,’ and contained, among 
other very interesting features, an admirable 
tribute to the value of the systematist and 
a somewhat caustic criticism of the ‘ species 
maker,’ helpful suggestions for the experi- 
ment station worker, and a very frank dis- 
cussion of the unfortunate results which 
attend the attempts sometimes made to com- 
bine politics and science. 
The following were elected to active mem- 
bership: G. B. King, Lawrence, Mass.; 
Gerald McCarthy, Raleigh, N. C.; E. P. 
Felt, Albany, N. Y.; A. F. Burgess, Mal-
