OUR DOMESTICATED ANIMALS. 115 



One of the most instructive papers on the prevalence 

 of ascarides in horses is that by Mr. Gr. Boddington, who, 

 writing some years back, says that ever since the com- 

 mencement of his professional duties, near Cardiff, he 

 "has been called upon, almost without intermission, to 

 prescribe for horses suffering from worms ;; (Veterinarian, 

 1859, p. 375). His treatment by means of aloes, in com- 

 bination with sulphate of iron, appears to have been 

 eminently successful ; four, five, and even six hundred 

 of the large lumbricoids coming away in particular 

 instances. 



In the present work I have not space to give 

 either the details or full references to other useful papers 

 on the lumbricoids of the horse ; but the various cases 

 and observations recorded by Messrs. Anderson, Litt, 

 Moir, Percivall, Poulton, and Tyndal, in the same 

 periodical, are particularly noteworthy. 



The wanderings of the armed strongle frequently 

 prove injurious, being occasionally fatal to the host. In 

 young colts they are especially liable to make their way 

 into the scrotum, or into its glandular contents, and when 

 lying within or upon the peritoneum they not unfre- 

 quently produce ascites. Cases of this description have 

 often been observed by Professor Simonds, and instances 

 are likewise recorded and commented on by Messrs. 

 Aitken, Clancy, Wright, the late Dr. Baird, and others. 



A characteristic example of death from this source 

 is given by Mr. Meyrick, of Welshpool (Veterinarian 

 for 1859, p. 695). Many additional fatal cases from 

 nematodes in the horse might be adduced ; some being 

 the result of the action of one species of parasite and 

 some of another. 



In this category of lesions may also be placed those
