OBSERVATIOIVS ON FOUR ilIUI.ES IIV MII^K.-

[Trauslation of a note coutained in "El Eepertorio" of Guanajuato, Mex. No XVII 



187G.] ' 



Although observations relative to the milk given by animals which 

 have not passed through the state of gestation are few, still a number 

 have been recorded, including some regarding the human species. 

 Fremy has given an analysis of the milk of a sheep and Schlossberger 

 of that of a goat. Facts of this nature being so uncommon, I believe 

 that the note which, conjointly with my learned friend Prof. Vicente 

 Fernandez, I now publish, will prove of considerable interest. 



On the nth of May, 1870, having learned that there was a mule in 

 milk at the Hacienda d'Argent de San Pedro de Eocha, on the Marfll 

 road, a quarter league from Guanajuato, I went to the place, accom- 

 panied by my friend Fernandez. Through the kindness of the em- 

 ployes of Mr. Bernardo Lopez, proprietor of the f\irm, we were per- 

 mitted to examine the phenomenal animal, which was then workin- in 

 an ore mill. * 



The mule is of a chestnut color, with the nose, lower parts of the 

 bmbs, belly, tail, and mane white. Its height is about 1^ meters: its 

 proportions are perfect, without fullness of the abdomen; the breast is 

 also larger than those of hybrids of the same kind ordinarilv; the back 

 IS quite concave. Except in these particulars, however, there is not the 

 least doubt but that we had before our eyes an ordinary mule. We 

 were told that it had been bought five years before, and, according to the 

 workmen, it was at least seven years old. On examination, however, I dis- 

 covered that the teeth resembled those of a horse four and a half or five 

 years old. It is possible that there is an anomaly here co-ordinate with 

 the peculiar appearance presented by the mamm«. The latterare shaped 

 like the alligator pear {Persca grattissima), black, and without nip- 

 ples. Their length is 12 centimeters, exclusive of the base, which is
