we find: GERMAIN corr. 86; the reason for the correction is however 
not stated. I have therefore written to Paris asking for information. 
Moreover I will observe that the difference of longitude Paris— 
Greenwich above used, must be increased according to the determination 
executed by French and English observers in 1902. The result 
obtained by the English observers was 9™20%,932 + 0°006; by the 
French observers 9™20s,974 + 08008. Mean 9™208953. (Monthly 
Notices of the R. A. 5. Jan. 1905). 
Finally we subjoin a comparison of the corrections to the moon’s 
ephemeris of the Naut. Alm. of 1874, furnished by the meridian 
observations on the one hand, and by NewcomB’s formulae on the other. 
It might be worth while to ascertain, whether the agreement of 
the results is improved, if we adopt the corrections according to 
NEWCOMB. 
As for the meridian observations, some have been made at other 
observatories (Leiden, Pulkowa ete.). I hope to investigate this more 
closely ; it is not probable however that the result will be greatly altered. 
A last remark in conclusion. According to the “Post en Telegraaf- 
gids” the isle of Mauritius is already connected telegraphically with 
Kurope. There is reason therefore to expect that the same will 
shortly be the case for Réunion also. In that case the “Bureau des 
Longitudes” will no doubt endeavour to obtain a telegraphically 
determined longitude of St. Denis.

Physiology. — “On the presence of sibringlobulin in fibrinogen 
solutions.” By Dr. W. Huiskamer. (Communicated by Prof. 
C. A. PEKELHARING). 
After Hammarsten had proved that in fibrinogensolutions, which 
had been coagulated either by heat to 55° or by means of fibrin- 
ferment, a proteid, afterwards called fibringlobulin, appears which 
coagulates at 64°, there existed several possibilities with regard to 
the formation or appearance of this proteid. 
Firstly the original fibrinogensolution might already have contained 
the fibringlobulin as an admixture; in the second place it was possible 
that at the heat-coagulation or by means of fibrinferment, the fibrin- 
molecule was disintegrated, and that in such a way that an insoluble 
substance, fibrin, is formed, along with a soluble one, fibringlobulin; 
and lastly the fibringlobulin might perhaps be an altered fibrinogen, 
which has remained in solution, a sort of soluble fibrin.
