the skin, which had previously raised and cleansed with 
care, of from five to fifteen mm. in length, involving the 
whole thickness of the membrane. The blood from the seat 
of operation was removed with a sponge, and particles of the 
tumour were then introduced into the wound. The largest 
wounds were closed by suture, the smallest were allowed to 
remain open. The matter used for inoculation was taken 
directly from the diseased animal or from a tumour which 
had just been removed, and care was exercised lest sup¬ 
purating or bleeding parts of it be taken. The operation 
did not last more than two minutes. Nowinski used 
medullary cancer, epithelioma and myosarcoma. Forty-four 
experiments with epithelioma conveyed from one horse to 
another and with medullary cancer from dog to dog gave 
only negative results. No importance was attached to the 
size of the inoculation wounds and of the inserted parts 
taken mostly from seats of inflammation. Each time 
suppurative inflammation of the wounds resulted. In 
another series of experiments made with similar matters to 
those mentioned above the results were in all cases positive. 
Here care was taken that the incisions were very small, and 
that the portions of new growth also were minute, not more 
than two millimetres in their longest dimension. The 
wounds soon cicatrised by first intention; but some months 
afterwards there formed at the seat of inoculation new 
growths of the nature of the inoculated matter. Hence 
the author concludes that tumours of the kind with 
which he has experimented are transmissible by inocula¬ 
tion, but that success of any experiments in this matter 
depends upon smallness of the particle introduced and 
smallness of the inoculation wound. Also communica¬ 
tion should be made between animals of the same 
species. 
“Researches on the pathogeny of Cataract,” by Deutsch- 
mann ( Grafe’s Arcliiv fur Ophthalmologie , 1877). The 
results of these researches are embodied in the following 
propositions: 
1. When we examine the crystalline membrane of a 
living animal or of a man we find between its anterior 
surface and epithelium of one side in its thickness, and 
between its posterior surface and the external layer of the 
other side, a thin layer of albuminous matter (subcapsular). 
In dissections, the crystalline being no longer protected 
from evaporation of its moisture, this albuminous layer 
coagulates under the form of brilliant and limpid droplets 
which bound regular polygonal figures. With staining by
