ANIMAL DISEASE AT NATAL. 
Lewis, of India, Bancroft, of Australia, and especially Dr. 
Manson,* of China, have pointed out, we must look for it 
wherever the blood circulates. 
Seldom is it that the oculist in his busy round stops to 
scrutinise the cataractous lens he so dexterously extracts* or 
to examine in minute detail every floating opacity in the 
vitreous body, and I must confess I am of the opinion that it 
behoves us to be more on the look-out for the phenomena in 
question .—Medical and Surgical Reporter.

ANIMAL DISEASE AT NATAL.

We have received the following Government Notice relating 
to diseases of Animals in Natal, which have been under in¬ 
vestigation by the Colonial Veterinary Surgeon Wiltshire : 
His Excellency the Lieutenant-Governor directs that the 
following Report of the Colonial Veterinary Surgeon be 
published for general information.

Colonial Secretary’s Office, Natal, 
July 8th, 1879. 
The Hon. the Colonial Secretary. 
Sir, —I have the honour to forward, for the information of 
His Excellency the Lieutenant-Governor, my Report on the 
work of my department during the past year. 
My investigations into the nature and causes of the dis¬ 
eases prevailing amongst animals has been continued on 
every occasion on which I have had an opportunity, but, in 
consequence of the war, the attention of stockowners and 
others has been directed to other matters than farming, and 
* In a paper entitled “Deport of Haematozoa,” Patk. Manson, M.D., 
of Amoy, China, says: “1. That a large ratio of the population of 
this province, and probably of other parts of China, is infested 
with the Jilaria sanguinis hominis. The exact ratio cannot yet be 
stated, but if my observations are a fair guide, one in thirteen is near it. 
2. That the Jilaria sanguinis hominis may be present in the blood, and yet 
the hosts be in good health and exhibit no morbid phenomena. 3. That in 
the same persons it may be present at one time and absent at another. 
4. That at one time or another it is generally associated with elephantoid 
disease , and is almost certainly connected with the causes of such affections. 
5. That it is sometimes associated with a diseased condition characterised 
by frequently recurring attacks of fever, accompanied by general anasarca, 
unconnected with heart or kidney disease.
