The Cattle-Plar/ue. 



The blood of a liealthy calf contained 4'53 parts of fibrine in 

 1000 parts, and 89'69 parts of corpuscles in 1000 parts. 



TJie blood of the same animal after the induction of the disease hij 

 inoeulatioji. — The fibrine rose to 4-85 parts per 1000, and the 

 blood corpuscles to 117-7 per 1000. The induced disease in this 

 case was slifjJit. The fibi-ine in a bad case, just before the 

 animal's death, amounted to 9"9 per 1000 parts. 



Calf in perfect 

 health. Imme- 

 diately after 

 being bled was 

 inoculated with 

 tears of sick 

 cow.

The above Table shows the results of three separate analyses 

 of the blood of the same calf — healthy, diseased, and restored. 

 The other analyses exhibit precisely the same changes, thoug-h 

 varying in such degree as we are led to expect from the tabulated 

 labours of Andral, GaV ARRET, and Delafond, Avho have 

 examined with great care the changes that occur in the blood of 

 domestic animals during the presence of disease* 



The conclusions arrived at by Dr. Gamgee would be of more 

 importance were they drawn from a wider field. He has made 

 but eight analyses : it will, therefore, be a matter of interest to 

 .see how far his views are confirmed by others who have been at 

 work in the laboratory. 



In milk he finds that the changes in its constitution are 

 uniform and marked : — 1st. The amount of sugar of milk is 

 remarkably diminished. 2nd. The amount of butter is (except 



Subjoined is the result of the analysis of the blood of 14 healthy neat cattle.
