The immediate caufe of this he takes to be a pre- 
ternatural thicknefs of the Blood occafion’d by a be- 
ginning Coagulation of thofe parts of it, which con- 
llitute the CrafTamentum, whereby the Globules of 
the Blood, and the particles of the Serum were im- 
prifon’d in a fort of Reticulum form’d by the Union 
of the Fibres of the Blood. 
The occafional Caufe of this Sicknefs he deduces 
from the cold and vvetnefs of the Seafon, which 
reign’d all the preceeding Year from Ofiober 1710, 
to November 17 1 1. Which Obfervation is worthy 
of remark, fince the Seafon preceeding the Mortality 
among the Cattle here in England was remarkably 
dry, and yet the Symptoms of the Didemper agreed 
With thofe obferv’d in Italy, as may appear from the Ac- 
count given by the Learned Mr. Bates, Surgeon to his Ma- 
jefty’s Houfhold in Philofophical Tranfaffions, No. 3^8 
For the particular manner in which this learned 
Gentleman endeavours to account Mechanically for the 
thicknefs of the Blood in thefe Animals, from the 
condition of the Seafon, and from that rhicknefs of 
the Blood to deduce all the particular Symptoms of 
the Diftemper, as likewife for his Conjectures con- 
cerning thofe Medicines, which might have been fer- 
viceable to the fick Cattle ; he not having made tryalof 
any, we mud refer the Curious to the Treatife it felf.
