TREATISE GN MiLClI COWS. 



my secret entirely ; my object was to get the reality of my discovery and its re- 

 sults attested to. The Academy, without adopting my conclusions, did neverthe- 

 less make honorable mention of me, at its sitting of the 3d of June following, in 

 these terms : 



" M. Francis Guenon, of Liboume, possessor of a method which he deems iufalhble for judg- 

 ing, by mere visual examination, of the goodness of Milch Cows, and the quantity of milk which 

 each can yield, has solicited the Academy to cause the efficaciousness of this method to be tested 

 by repeated experiments. The case presented by this request was one of a secret method of 

 judging, which the possessor was not willing to reveal. On the other hand, it seemed difficult to 

 admit that the external signs, whatever they might be, by which M. Guenon judges, could al- 

 ways bear a proportional relation to the quantity of milk yielded by a Cow. Jyevertheless, the 

 Academy deemed it proper to appoint a Committee charged with making the examination. 



"Trials have been made, with the care and under the precautions necessarj- for precluding all 

 collusion. The Cows used for the purpose belonged to three different herds, and amounted to 

 thirty in number , and the result has been to establish, to the satisfaction of the Committee, that 

 M. Guenon really possesses great sagacity in this line. So long, however, as his raetliod shall be 

 kept secret, it cannot be judged of nor rewarded by the Academy. 



" Governed by these considerations, the Academy, having ascertained from M. Guenon that he 

 is w^lling to submit to every test that may be proposed, and to disclose his secret upon receiving 

 a just indemnity, has referred him to the Prefect, and has engaged to recommend him to the fa- 

 vorable notice of that magistrate, who is ever disposed to promote all that tends to improvement." 



Here the matter rested at that time. I did not then make up my mind to give 

 my secret to the public ; but I persevered in my observations and experiments, 

 in order to perfect my discovery. In 1837, the Agricultural Society of Bordeaux 

 deiermined to ascertain for itself what reality there might be in my system. — 

 The result surpassed its expectation ; the experiments made, in presence of the 

 Committee appointed for the purpose, left no doubt as to the certamty of ray 

 method. Here are the terms in which the Committee expressed themselves in 

 their report : 



AGRICULTURAL SOCIETY OF BORDEAUX. 



GUExNON DISCOVERY .... MILCH COWS. 

 Report to the Agricultural Society of Bordeaux. 



Gentlemen : The Committee appointed by you to examine into the discoveries of M. Francis 

 Guenon. of Liboume, have the honor to .submit to you the result of their investigations. 



M. Gueoon has establi.ahed a natural method, by means of which it is easy to recognize and 

 class the different kinds of Milch Cow.s, according to 



1st. The qrtantity of milk which they can yield daily. 



2d. The period during which they will contimte to give milk. 



3d. TTie quality of their milk. 



Down to the present day. Gentlemen, the writers and professors who have the most particu- 

 larly occupied themselves with the bovine race have been unable to do anything more than indi- 

 cate some vague signs forjudging of the fitness of Cows for secreting milk. 



After more than twenty years of observations and researches, M. Guenon has .succeeded at 

 length in discovering certain natural and positive signs, which constitute the basis of his method; 

 a method henceforward proof against all error. 



Sensible of the necessity that your Committee should be fully convinced, and that they coald 

 not but look with some degree of distrust upon any results of the proposed trials of his method, 

 unless they should know that tho.se results rested upon tangible facts, and were nowise depend- 

 ent upon guess work, M. Guenon began by imparting his secret to your Committee, and making 

 them fully acquainted with the positive signs upon which he has founded his method. By means 

 of these signs, which are all external and apparent, he has established eight classes or families, 

 which embrace all the varieties of the Cow that are to be met with in the different parts of tliiB 

 kingdom. Each of these classes or families is subdivided into eight orders. It is divided, also, 

 jnto tliree sections, so that each of the sections comprehends the eight orders; this last division
