REVIEW. 
Systdme Guenon , 
In consequence of, in the interim, having received a visit 
from a French gentleman of the Veterinary School of Toulouse 
— M. Gourdon, chef-de- service d’Anatomie there — who has 
kindly put us in possession of what we are to understand by 
the escutcheon in cows. Standing directly behind a cow, her 
tail being carried to one side, we perceive on either side a 
waving longitudinal line, consisting of a row of curled or re- 
versed hair, which is sometimes found running along the pos- 
terior part of the thigh, sometimes down the posterior part of 
the udder, and, now and then, in the latter case, united by a 
waving cross-line of similar hair with the longitudinal line of 
the opposite side. Now, it is the space included between 
these lines or rows of hair, bounded above by the vagina and 
below lost upon the advancing surface of the udder, which con- 
stitutes what the French have named Vecusson , and the English 
must or do call THE ESCUTCHEON ; by the breadth or extent 
of which, French cow-keepers, and veterinarians who are 
in the habit of visiting dairies, have been for many years 
in the habit of estimating the character of a cow as to her 
milking qualifications. If the escutcheon be broad, then is the 
cow supposed to be a good milker ; if narrow or circumscribed, 
she is the reverse. To what extent this systeme is known or 
practised in our own country, or whether it is altogether a 
novelty to our countrymen, be they cow-keepers or cow-dealers 
or veterinarians, probably some of our readers, now the matter 
comes thus plainly before us all, will have the kindness to 
inform us ; meanwhile, for our own part, we cannot altogether 
remain unsceptical. 
M. Riquet read a paper to the Society 
On a 'particular Fluid secreted within the Cavity of the Pharynx 
of the Horse , 
From an analysis of which the results are — 
1. That the pharyngeal cavity of the horse is the seat of a 
peculiar and very abundant secretion. 
2. That, in health, this fluid passes from the pharynx into 
the esophagus through an act of a particular kind connected 
with deglutition.
