Pharyngitis of the Horse, and its Cure by Laryngeal Injec¬ 
tions of Prussic Acid,” wherein he says: 
“ Although the results in the treatment of inflammatory 
affection of the respiratory mucous membrane in coryza, 
adenitis equorum, scalma, etc., were very unsatisfactory, 
with the remedies employed so far, namely : to cut short the 
morbid process, fault must not be found with the physiologi¬ 
cal action only, but also in the mode of application. As 
these agents are introduced mainly through the mouth, it is 
impossible for them to come in direct contact with the affect¬ 
ed mucosa, and thus a local influence is almost excluded.” 
Local methods of treatment promised much better results, 
as through the examinations of Prof. Dr. Schuetz it was 
proven that the diseases in question nearly always, in their 
primary stage, present a limited infectious inflammation of 
the surface of "the mucous membrane. Again, the experi¬ 
ments of Prof. Dr. Dickerhoff have also shown that the local 
treatment of the respiratory mucosa is easily accomplished. 
Therefore, if the proper remedy be found, the result will be 
satisfactory if the local treatment be adopted in time. 
Dr. [’Jelkmann being guided by the above views, made 
numerous experiments, and applied man} r expedients which 
were recommended, and others which had not yet been put 
to test. 
The first opportunity presented itself in a large transfer 
stable at Frankfurt, M., among horses affected with in¬ 
fectious laryngo-pharyngitis, a scalma enzootic. 
Among one hundred horses in an enclosure, some sixty 
took sick within six Aveeks, at intervals of one, two and four 
days. It being midsummer, those patients, six in number, 
Avhich took sick in the first three days were isolated and 
placed in a large, roomy, well-ventilated hall. 
The internal treatment with the remedies known as 
promoters and regulators of morbid slime secretion, etc., Avas 
carried out from the first to the seventh day, but seemed to 
have no visible effect, nor did the externally applied 
derivans. 
In consequence, laryngeal injections were made as an ex-
