per cent alcohol (1 and 2 were bacilli stains). 3. Section 
staining for one hour in Weigert’s solution for coloring 
elastic fibres. 4. Rinsing in 96 per cent alcohol (3 and 
4 were elastic fibre stains). 5. After coloring in lithium 
carmine and washing with muriated alcohol (for contrast- 
ing coloration, nuclei and protoplasm coloring). 6. Ab- 
solute alcohol, xylol and balsam. In these preparations 
the bacilli were dark red with a tinge of violet; the elas- 
tic fibres were dark blue; the remaining tissus of the 
contrasting coloration were light red with more darkly 
stained nuclei. Care must be taken not to make the lith- 
ium carmine staining too intense; the red bacilli staining 
was always clearly recognizable against the voilet-tinted 
red ground-work. Hartog mentions the following pro- 
cess applied to a large tumor mass of tuberculous tissue 
from the human subject. A piece was hardened in 10 per 
cent formal, then placed in 96 per cent alcohol, and final- 
ly in absolute alcohol. The pieces were then put in al- 
cohol-ether and imbedded in celloidin. Sections of 0.015 
millimetre thickness were then stained after the van Gie- 
son method. Finally colored with the Weigert stain for 
elastic fibres.— Post-Graduate. 
A Book Under the Microscope. 
To discover the operations of protective tariffs and how 
high prices are maintained, we invite a microscopic in- 
spection of these facts as toa small book on microscopy 
recently published both in London and America. 
This book was printed and retailed in London for about 
60 cents, per copy. The postage is about five cents and 
there is no duty on single copies sent direct to purchasers. 
But to buy from him you must outwit the London pub- 
lisher by getting some friend to secure and mail to you a 
copy. Send the London retail price to the London pub- 
lisher and he will refuse to sell to an American though he
