SOCIETY MEETINGS.

tive point of appearance, accompanied by a slightly intense red¬ 
ness of the skin, with a deeper swelling hard cedematous of the 
parts. We explain this swelling in remembering that the lym¬ 
phatic apparatus generally participates early in the diseased pro¬ 
cess. We see in the direction of the lymphatic vessels appear red 
streaks, hot, sensible, often hard. Lymphatic glands in the re¬ 
gion where the disease is seated undergo an acute considerable 
tumefaction ; if one cuts the swollen part, there escapes sponta¬ 
neously or by a slight pressure a clear, yellowish liquid, which a 
little while after expression spontaneously coagulates. It is a 
liquid analogous to that we know as lymph, a fibrogenous liquid 
which does not coagulate, but remains liquid as long as it is enclosed 
in the interior parts, away from the contact with atmospheric air. 
We can explain in two ways how this substance accumulates in 
large quantities: at first it is produced in the tissues by the in¬ 
flammatory process, it transforms a greater quantity of other ma¬ 
terial in fibringenetic substance ; then that substance which in 
the normal condition should be withdrawn as an element of the 
lymph, remains in the parts, since all currents cease in the lym¬ 
phatic vessels. This is explained by the swelling of the lymph¬ 
atic glands produced by an increase of the cellular elements. 
In the discussion that followed, and in answer to a question as 
to the formation of a line between lymphangitis, cellulitis and 
elephantiasis, said the two former were, as a rule, acute, and gen¬ 
erally could be removed, which was not the case with the latter ; 
yet admitted that it at times followed lymphangitis. Dr. Liau- 
tard agreed with this, and said he did not believe that true ele¬ 
phantiasis of the hind legs was so common as generally supposed. 
After passing a vote of thanks to the essayist, the meeting 
went into executive session. 
The Board of Censors reported in favor of the applications for 
membership of N. E. Cuff and L. James, V. S., who were duly 
elected. 
On motion, meeting adjourned till second Tuesday in Septem¬ 
ber, Dr. Charum being appointed essayist for the evening.
