Facts and Observations. 
Rabies in a Cow. — A few days ago, a cow belonging to 
Mr. William Shackleton, farmer, Alcomden, near Hebden 
Bridge, appeared to be suffering from some strange disorder. 
A veterinary surgeon was called in to examine the animal, 
and pronounced it to be a case of hydrophobia. Previous to 
its death the animal became very violent, and showed all the 
usual signs of this disease. Some time ago a strange dog 
was prowling about the farmstead, and bit the farmer’s dog, 
but it was immediately destroyed. It is thought the cow was 
bitten at that time. During the past few months many 
cases of this kind have occurred in the same neighbourhood. 
Dogs, pigs, cats, cows, horses, have been attacked, destroyed, 
or died from the effects of hydrophobia. Several human 
beings have been bitten, and last week a man died from the 
effects. — Standard. 
The Relation as to Area between the Tendon 
and the Muscle. — Professor the Rev. Samuel Haughton 
has lately published some interesting observations on this 
subject, and especially in regard to the supposed ratio between 
the cross section of the muscle and its tendon. He con- 
cludes that the cross section of a muscle does not bear a 
constant ratio to the cross section of its tendon, unless the 
friction experienced by the muscle and tendon be also con- 
stant, and that there may even be a surplusage of strength in 
the tendon beyond what is absolutely necessary to resist the 
combined force of the muscle and friction. This surplusage, 
however, cannot be supposed to be large, if the principle of 
economy of material in nature be admitted. — Popular Science

Cinchona. — The culture of the cinchona, or Peruvian 
bark, in St. Helena, is progressing satisfactorily. The plants 
are all in excellent health, and have a fine green, vigorous 
appearance. There are now about 4000 planted out, and it 
is thought a sufficient number can be obtained from them to 
stock the whole colony. — Journal of the Society of Arts. 
Experiments in Tinea Favosa. — At a late meeting 
of the French Academy, M. de St. Cyr sent in a memoir 
detailing his experiments in the extension of this parasitic 
affection. He made some of his experiments on dogs, 
and he has since found that all the mice in the same
