PREFACE BY THE EDITOK. 



now that this discovery has been made, and proclaimed, on the ground of repeated trials and testi- 

 mony, to all appearance conclusive, what is there in the theory tliat lactiferous sscretions should 

 produce and show themselves in external marks and cutaneous exudations, any more -wonderful 

 or out of the way, than that other secretions and faculties are known to produce not only marked 

 diirerences in form and color, but even perceptible, and, for the most part, offensive (jfluvia? 



Observe the effect, in these respects, not only in the external differences of color and shape, 

 which mark the different seaxs, but the no less striking effects j)r.odu.ced by early emasculation of 

 tlie horse, the bull, the hog, and the goat ! Hence, it is only " if I were hungry" says the Psalm- 

 ist. "I will eat the flesh of hulls, and drink the blood of goats" 



The famous Tuscany Ox, so celebrated for strength, activity, and endurance, and which Com> 

 modore Jones, in one of his letters addressed from the Mediterranean to Mr. Skinner, says will 

 travel 22 miles a day, with heavy loads of ship timber, is, all over, of uniform light grey color; but 

 leave him unabridged of his full sexual proportions, and the effect is sure to be exhibited in the 

 black color and great enlargevient of the neck, and curly forehead. Is it, then, we repeat, extrOg, 

 ordinary or incredible that the milky secretions of the Cow should produce, in the region where 

 that process is carried on, and where her characteristic excellence lies, effects not more visible or 

 striking than are produced on the size, color and growth of the hair, on the shoulders, neck and 

 head of the bull ? Are the external signs — the difference in the growth and curl of the hair, con- 

 stituting the " escutcheons," and the scurf or dandruf thrown out on tb.e akin, as described in this 

 book — anymore remarkable or strange in tne one case than the other? But — "allAhingsare 

 strange" — until they are found out I
