further localized or aggravated by the presence of the worms or 

 embryos in their bloodvessels. ' It also leads to ansemia or irregu- 

 lar circulation in the brain, aggravated by embolism of the cere- 

 bral arteries with fainting, collapse, paresis, convulsions, and 

 intellectual disturbance. lyameness of one hind limb with wasting 

 of its muscles and even paralysis or paraplegia is not uncommon 

 (especially in Great Danes) and may be due to obstruction of 

 the vessels, to localization of groups of worms in the connective 

 tissue, to impaired circulation in the spinal cord or even in the 

 brain. The patient may become morose, or snappish so that the 

 case may be mistaken for rabies. There may be polyuria, albu- 

 minuria, uriniferous casts, and epithelium, and the embryo is said 

 to be passed in the urine, but absolute proof of this is lacking. 

 Intermittent pulse and heart sounds, inequality of successive 

 beats, palpitations and valvular murmurs are sometimes present. 

 When the lungs are affected there are cough, dark red mucosse, 

 flatness on percussion over limited areas, and crepitation or other 

 modification of the respiratory murmur. Progressive emaciation 

 and ansemia are common, with encreasing weakness. 



An absolute diagnosis may sometimes be secured by drawing 

 •a little blood during the night and examining it microscopically 

 for the embryos 280 ;i* in length and furnished with delicate 

 pointed tails. The embryos are often found in enormous num- 

 bers in the blood of dogs that show symptoms of ill health. 



Treatment of these cases has been attempted by giving oil of 

 turpentine 30 drops, in pill, daily for a week, and again by Bor- 

 deaux turpentine )4 to i drachm, in pill, daily. I have obtained 

 a steady improvement by giving daily 10 drops of a one per cent, 

 solution of arsenite of soda in combination with nux. As in all 

 parasitic diseases much depends on sustaining the general health 

 so that a rich diet of easy digestion may enable the animal to 

 bear up until the worms have completed the term of their natural 

 lives, when, if no more are taken in, a recovery may ensue. The 

 patient must, of course, be denied access to all standing water in 

 which the embryos of the worms may be found. 



Haematozoon Lewisi. Filaria Recondita. The embryos 

 of one or more nematoids have been found in large numbers in 

 the blood of the dog by Gruby and Delafond, Lewis, Manson, 

 Sonsino, Grassi and others. The haematozoon Lewisi is 280 /i
