THe Microscope. 67 
We take pleasure in calling the attention of our readers to 
the Facility Nosepiece which is advertised in this number 
for the first time. We have one on our own microscope, and 
shall have them on all the microscopes in our laboratory as 
soon as possible. 
We are surprised to learn, through a private letter from Mr. 
Cole, of London, that the subscription list to his publica- 
tions is practically nothing in this country. ‘ The Methods of 
Microscopical Research,” ‘‘ Studies in Microscopical Science,” 
and ‘“ Popular Microscopical Studies,” all are edited by Mr. 
Cole, and issued weekly. It is the most complete and valuable 
series of “studies” ever published, and should have a generous 
support by American microscopists. The editor will send a 
complete prospectus free. Address, Arthur C. Cole, F.R.MLS., 
St. Domingo House, Oxford Gardens, Notting Hill, London,W.,

THE GERM OF SWINE—-PLAGUE. 
iis a lengthy article in Sczence, for Feb. 8, 1884, the writer 
gives an abundance of facts to prove that Klein is not 
entitled to the discovery of germ of the swine-plague. The author, 
D. E. Salmon, concludes by saying: ; 
“Tt is a matter of record, therefore, that the organism 
which constitutes the cause of swine-plague was first discovered 
by Klein in 1876, but that he failed to connect it in any way 
with the virus of the disease, and afterwards concluded that it 
depended upon a very different schizophyte. It is alsoa matter 
of record that I was the first to demonstrate by satisfactory 
methods that this micrococcus exists in the blood during the - 
life of the animal, that it can be cultivated in flasks, and that 
the sixth successive cultivation, made in considerable quantities 
of liquid, and which contained no other form than micrococcus, 
still produced the disease. Neither Pasteur and Thuillier, nor
