348 CHYLE, LYMPH, TRANSUDATES AND EXUDATES.
the sac-like dilated lymphatic vessels of the spermatic cord. No. 4
was made by C. Schmidt 1
the data being obtained from lymph from the
neck of a colt. The results are expressed in parts per 1000.

Water 939.9 934.8 957.6 955.4
Solids 60.1 65.2 42.4 44.6

Salts 7.3 8.2 7.2 7.5
The salts found by C. Schmidt in the lymph of the horse have the
following composition, calculated in parts per 1000 parts of the lymph:
Sodium chloride 5 . 67
Soda 1.27
Potash 0. 16
Sulphuric acid . 09
Phosphoric acid united with alkalies . 02
Earthy phosphates . 26
In the cases investigated by Munk and Rosenstein the quantity of
solids in the fasting condition varied between 35.7 and 57.2 p. m. This
variation was essentially dependent upon the extent of secretion, so that
the low amount coincides with a more active secretion, and the reverse
in the other case. The chief portion of the solids consisted of proteins,
and the relation between globulin and albumin was as 1 :2.4 to 4. The
mineral bodies in 1000 parts lymph (chylous) were: NaCl 5.83; Na2CC>3
2.17; K2HPO4 0.28; Ca3 (P04) 2 0.28; Mg3 (P04) 2 0.09; and Fe(PO4)0.025.
The quantity of titratable alkali in the lymph is much smaller than in
the blood. Carlson, Greer and Luckhardt2
have recently made com-
parative estimations of NaCl in blood-serum and lymph of the same
individual (horse and dog) and find that the lymph is regularly richer in
chlorides, a condition which, according to them, is difficult to reconcile
with the view of the filtration and transudation processes in the forma-
tion of lymph.
In this connection it must be recalled that according to many inves-
tigators the lymph has a somewhat higher osmotic pressure and therefore
a somewhat greater molecular concentration than the serum. Carlson,
Greer and Becht 3 found, nevertheless, that the osmotic pressure of
neck-lymph in the dog is often lower than the serum.
