KNOWLEDGE OF ANATOMY. 259 



signified my objections to stimulating the bowels and kid- 

 neys by cathartics and diuretics as aids of training, and I 

 must, necessarily, show that condition can be acquired 

 without their help. Sweating has two distinct things to 

 perform : the first, to give freedom to the respiratory or- 

 gans and the action of the heart, which we may call inter- 

 nal relief; the second, to promote the strength and activity 

 of the muscles, and lighten the load to be carried, which, 

 with the same propriety, may be termed external relief. 

 The organs of respiration are the lungs, bronchial tubes, 

 trachea or windpipe, glottis or valve, at the extremity of 

 the trachea, nasal passages and nostrils. Knowing that I 

 am incapable, it would be foolish in me to attempt a lecture 

 on hippophysiology, and in offering the remarks I am go- 

 mg to make, I do not present them as being scientifically 

 correct. I lament greatly the want of a suitable knowledge 

 of anatomy and physiology, which would have lightened 

 my labor in many instances, and when I have been groping 

 in the dark, uncertain whether the little glimmer I could 

 discover was a scintillation which could be depended oh, 

 or a false light that would lead me further astray, the pos- 

 session of this knowledge would have enabled me to detect 

 the imposture, and pursue the right course without the loss 

 of time. If it were my intention to continue in the busi- 

 ness of training horses I would, notwithstanding my age 

 which makes it harder work to learn devote a portion 

 of my time to this study which I have neglected, and by 

 enrolling myself in the class of some competent instructor 

 in veterinary science, try to rectify the want by rigid study, 

 especially in those branches pertaining to respiration. 



It requires study to understand the workings of the or- 

 gans of circulation and breathing, and I must admit that 

 I am not capable of understanding any of the treatises 

 that I have read on this subject sufficiently to explain them, 

 or to make them even as intelligible to you as they are to
