DISEASED LUNGS IN SHEEP. 
Mr. C. R. Hall, of Torquay, writing to the “ Editor of the 
Medical Times and Gazette ,” respecting the report of the 
“ Pathological Society/ 5 which was transferred from the pages 
of that journal to ours (see p. 70S, last volume), says, “Dr. 
Ranke’s communication is emphatically entitled, ( A Form of 
Disease now very prevalent in the Lungs of Sheep. 5 May I 
refer Dr. Ranke to the ‘British and Foreign Medico-Chirurgical 
Review’ for 1856, p. 49, where he may read an account, 
and p. 473, where I have given an engraving, of the same 
eritozoic disease in the lungs of sheep ? Dr. Ranke has 
found, of eighteen lungs examined, only two or three in a 
healthy state. For many years past, ever since indeed my 
attention was first directed to the subject, I have never seen 
one lung of a full-grown sheep entirely free from more or less 
of entozoic disease. The division between lamb and sheep 
being somewhat arbitrary, and this being an acquired and not 
a congenital disease, may explain the difference. 
“ There is not the smallest reason to infer that such sheep 
produce mutton which when cooked is capable of introducing 
the germs of entozoa into the human stomach. But whether 
or not the lungs themselves would be certain to have all their 
communicable germs destroyed by the ordinary mode of 
cooking what the butchers sell to the lower classes as sheep’s 
or lamb’s 4 pluck,’ is perhaps more doubtful. 
“ My object in writing this is merely to show that the title 
of Dr. Ranke’s communication might be altered to that of 
c A Form of Disease, perhaps, universal in the Lungs of 
Sheep, which has existed for the last fifteen years, and pro- 
bably for an indefinite period previously. 5 
“ The mode of development of the entozoa is a subject of 
much interest, and I hope to read Dr. Ranke’s account of it 
in full detail in the next volume of the Society’s Reports.” 
SOURCES OE FLUORINE IN THE ORGANISM. 
M. M. J. Nickles gives as the result of his researches on 
the diffusion of fluorine : 
I. Fluorine exists in the blood, in very small quantities. 
II. There is also some in the urine. 
III. There is also fluorine in the bones, but much less 
than has been said. According to Berzelius, 100 grammes
