340 THE MICROSCOPICAL NEWS. 
ALL MATTER intended for publication must be sent before the 
12th of each month to the Editor, Mr. George E. Davis, The 
Willows, Fallowfield, Manchester. 
DURING THE COMING YEAR we hope to be able to arrange for a 
series of articles ‘‘On the use of the Microscope in detecting the 
adulteration of food.” 
Dr. HOLMES AND THE MicroscopE.—In a recent speech, Dr. 
Oliver Wendell Holmes,—the ever charming “ Autccrat of the 
Breakfast Table,” in illustrating the microscopic facilities of the 
Harvard Medical School, said: “ A man five feet high, enlarged to 
correspond with the microscope power used, would be a mile high, 
would weigh 120,000,000,000 pounds, and could pick up the 
Boston State House and chuck it into the sea, cleaning out that 
ancient structure by a summary process which would put to shame 
the exploits of Commodus and his kind.” 
EDUCATIONAL SLIDES.—Mr. W. G. Rothwell has sent us some 
of his educational slides for examination, and we have no hesitation 
in saying that they are the best of the kind which have ever been 
brought under our notice. The section through the embryo of 
the grain of wheat is unusually good, while the thorn formation is 
well shown by sections of Raspberry, Dog-rose, Blackberry, &c. 
Co.e’s StupiEes.—Nos. 5 and 6 of the second volume of these 
“Studies ” have been issued during the past month. No. 5 con- 
tains a coloured plate “ Blood of Frog” double stained, the letter- 
press being devoted to a “Description,” and the method of 
“ Double staining amphibian blood.” Volume II., No. 6, is really 
Section 2, No. 3, and in this, the cell theory is continued, with a 
coloured illustration of the siliceous valve of Avrachnotdiscus 
LEhrenbersit. 
On Noy. 18th, the fourth part of “The methods of Micros- 
copical Research” was issued, containing a dissertation on “ The 
preparation of Animal tissues.” 
ANIMAL HistoLtocy.—Mr. Stanley, of London Bridge, has just 
issued for the use of students in Animal Histology, a set of twenty 
stained sections, in tubes ready for mounting and previous examina- 
tion. These sections will be found a great boon by students, as 
they will be able to try the effect of reagents upon them before 
putting them up as permanent objects. A circular is issued with 
them, detailing the method of mounting and what to observe in 
the finished slides. ‘The sections comprise the following :—Costal 
cartilage, Epiglottis, Bone, T. S., Bone, L. S., Finger of Feetus, 
Ventricle of the Heart, Brain, Spinal Cord, Lung, Lung showing 
deposit of carbon from London smoke. Tongue, Kidney, Liver, 
Salivary gland, Thyroid gland, Scalp V. S., Scalp H. S., Skin of 
sole of foot, Testis, and Ovary.
