this an appreciable advantage lias resulted in tlie discovery of the tuberculous 
bacillus. But it is to be hoped, that also in other respects something may be 
gained by it, which can be made useful in fighting the disease. After the ex¬ 
periments already undertaken no great outlook appears to exist in a therapeutic 
direction, of finding successful means of influencing the parasites in the body 
of the patient. I would lay so much more value upon the prophylactic mea¬ 
sures. These must partly be directed to directly destroying the tuberculous 
bacilli by suitable methods of disinfection, partly they must strive to preserve 
the healthy from contact with the tuberculous bacilli in all those conditions 
in which a reliable destruction of the parasites is not possible. 
It appears to me not to be too early to proceed against tuberculosis with 
prophylactic measures. But owing to the great spread of this disease, all steps 
which are taken against the same will have to reckon with the social condition, 
and, therefore, it must be carefully considered in what way and how far one 
may go on this road without prejudicing the advantages gained, by unavoid¬ 
able disturbances and other disadvantages. It would lead too far to go into 
a detailed discussion of the prophylaxis in this place, and I reserve my views 
in regard to it for another opportunity. 
GENERAL LYMPHANGITIS. 
An article read before the California State Veterinary Medical Association, 
December 13, 1888, By Dr. J. P. Klenoh, V.S. 
There has been, for the last six years, existing among the 
equine species of California, and more especially amongst the 
mules, a general constitutional disease, which has proven fatal 
in nearly every instance, and that has caused death after sev¬ 
eral months of loathsome suffering and of pitiful distress, un¬ 
less the owner, having lost confidence in the final curability 
of the affection, concluded to destroy the animal for the sake 
of humanity or self-protection. 
This affection has not been, to my knowledge, submitted 
to a diligent study by any practitioner, nor has there been 
any particular description given of it by the veterinarian 
authors, pvith the exception of a few practical records that 
appeared in some veterinary publication. 
I had the good fortune of following several cases in vari- 
ous localities of two counties from the very first start of the 
disease to the time the animals were destroyed, and took 
careful notice about the origin and the progress of the symp¬ 
toms, as well as of the pathological lesions after death. I am
