Bots in Horses — Incubation.

From the American Farmer. 



Bots iu Horses* Mjiri-ain ti» Cattle* 



It is tlie duty of every person Vvho has any 

 experience in the treatment of diseases in 

 tliat noble and useful animal, the horse, to 

 communicate it to the public. 



It was my province a few years since to 

 have much to do witli that noble animal, and 

 of course among the number in my possession, 

 I would iind a number that would be diseased, 

 and very otlen my skill and experience would 

 be taxed to find a remedy for some of the dis- 

 eases to which they would be very otlen sub- 

 ject. 



The most formidable disease to which this 

 noble and useful animal is addicted, and there 

 is none more alarming in its attacks, is the 

 bots. 



I had consulted the hig^hest authorities in 

 the veterinary art for the treatment of this 

 disease, and faithfully used the remedies laid 

 down, without any benefit. I was induced 

 from interest, and also for the very high re- 

 gard which that noble animal, the horse, held 

 in my estimation, to use every expedient in 

 my possession, to cure this formidable dis- 

 ease. I had another motive — I had lost seve- 

 ral very fine horses by this disease, which in- 

 duced me to use and try every experiment 

 which my ingenuity could invent, to arrest 

 this disease among my horses, and prevent, if 

 possible, its recurrence among them. 



I am satisfied, and feel convinced, that I 

 will offer to the public, an infallible remedy 

 for tiie bots. 



Some six years since, I purchased a very 

 fine horse, but he had the appearance of labour- 

 ing under some disease. I commenced a 

 course of treatment, which I tliought would 

 relieve him, and which I had pursued in the 

 treatment of some other hprses which had the 

 appearance of being diseased in a similar 

 manner to the above mentioned horse, with 

 decided relief; but in this case all my reme- 

 dies failed of their desired effect. 



I was induced to try the use of lime in the 

 treatment of his case, as I was confident he 

 was filled with grubs or bots, as he had dis- 

 charged several, t commenced by giving 

 him a table-spoonful of slaked lime three times 

 per week, in bread mashes. Afler pursuing 

 this course near too weeks, the bots began to 

 pass off in quantities varying from ten to 

 twenty, which he would expel during the 

 night, from his intestines. In the meantime 

 his appetite began to improve, and in six 

 weeks he was one of the finest looking geld- 

 ings I ever saw. From that day to this, I 

 have kept up the use of lime among my 

 horses, with decided benefit. As an evidence 

 of its good effects, I have not lost a hoi'se 

 since I began to use it. * 



A large number of the bots which he would 

 expel from his intestines, had the appearance 

 of being dead. I was induced from this fact, 

 to put some of them in a strong solution of 

 I lime-water, as I had frequently put them in 

 spirits of turpentine, without producing any 

 efiect on them ; but all those that I put into 

 lime were perfectly dead in eight and forty 

 hours. 



Lime is a certain preventive in keeping 

 cattle from taking the murrain. As an evi- 

 dence of tills fact, I have used it among my 

 cattle three times per week, mixed with salt, 

 for three or four years. In that time I have 

 not lost a single cow, or steer, or ox, by this 

 disease ; in the meantime, some of my neigh- 

 bours have nearly lost all the cattle they 

 ovvned. 



I will give you a stronger case than the 

 one above mentioned. One of my neighbours 

 who lost all his cattle, had a neighbour living 

 within two hundred yards of him, who had 

 several cattle which ran daily with those that 

 died, and his cattle all escaped. He informed 

 me he made it an invariable rule to give his 

 cattle salt and lime every morning. 



I have no doubt it is a sure and infiiUible 

 remedy for bots in horses, and a preventive 

 of murrain among cattle. J. W. J.

Inculsationt 



The progress of the incubation of the 

 chicken is a subject curious and interesting. 

 The hen has scarcely sat on the egs^ twelve 

 hours before some lineaments of the head and 

 body of the chicken appear. The heart may 

 be seen to beat at the end of the second day ; 

 it has at that time somewhat the form of a 

 horse-shoe, but no blood yet appears. At tlie 

 end of two days, two vesicles of blood are to 

 be distinguished, the pulsation of which is 

 very visible : one of these is the left ventri- 

 cle, and the other the root of the great artery. 

 At the fiftieth hour, one auricle of the heart 

 appears, resembling a noose folded down 

 upon itself The beating of the heart is first 

 observed in the auricle, and afterward in the 

 ventricle. At the end of seventy hours the 

 wings arc distinguishable; and on the head 

 two bubbles are seen for the brain, one for 

 the bill, and two others for the fore and hind 

 part of the head. Toward the end of the 

 fourth day, the two auricles, already visible, 

 draw nearer to the heart than before. The 

 liver appears toward the fifth day. At the 

 end of a hundred and thirty-one hours, tlie 

 first voluntary motion is observed. At the 

 end of seven hours more, the lungs and 

 stomach become visible, and four hours after 

 this, the intestines, the loins, and the upper 

 jaw. At the hundred and forty-fourth hour, 

 two ventricles are visible, and two drops of
