No. 3, Worms in the blood of a dog. — Reynedy for Indigestion. 



75 



of mammiferoiis animals, we are most anx- 

 ious to communicate to the Academy the 

 discovery which we have made of entozoa 

 circulating in the blood of a dog of a vigor- 

 ous constitution, and in a state of apparent 

 good health. 



These worms are from three to five mil- 

 liemes of a millimetre in diameter, and 

 alrout twenty-five in length. The body is 

 transparent and colourless. The anterior 

 extremity is obtuse, and the posterior or 

 caudal extremity ends in a very fine thread. 

 At the fore part, a small, short furrow, five 

 miliiemes of a millimetre in length is ob- 

 served, which may be considered as the 

 mouth. 



By all its characters, this species of hee- 

 matozoa must rank in the genus Filaria. 



The motion of these animals is very lively. 

 Their life continues even ten days after the 

 blood has been drawn from the vessels and 

 deposited in a vessel placed in a tempera- 

 ture of 59® Fahr. 



By examining a drop of blood under the 

 lens of the microscope, we see these hsema- 

 tozoa swim with an undulatory movement 

 between the globules of blood ; they curl, 

 imcurl, and twist about with great vi- 

 vacity. 



In order to be certain whether these 

 worms existed in the whole circulatory cur- 

 rent, we examined the blood of the coccy- 

 geal arteries, those of the external jugular 

 veins, of the capillary, of the conjunctiva, 

 and of the mucous membrane of the moutli, 

 of the skin, and of the muscles, and we 

 were always able to detect entozoa. 



For the last twenty days we have daily 

 opened the capillaries of the different parts 

 of the skin, and of the mucous membrane 

 of the mouth, and always find these animals 

 present. 



The urine and excremental matters do 

 not contain them. 



The diameter of the globules of the blood 

 of the dog, is from seven to eight miliiemes 

 of a millimetre ; that of the Filaria is from 

 three to five. There is therefore not the 

 least doubt but that this worm can circulate 

 wherever the blood has to pass. We reckon, 

 according to several investigations made in 

 order to ascertain the quantity of blood ex- 

 isting in the vessels of dogs of moderate 

 size, that the dog in question has lkii-500 of 

 blood in circulation. Now a drop of this 

 blood weighs 0kii067, and in this drop we 

 are able to detect from four to five Filaria. 

 This dog would therefore contain more than 

 100,000 of these worms in the whole of its 

 blood. 



The prodigious number of the animals is 

 the more astonishing, as the dog seems to 



be in good health. We should however re- 

 mark, that the entozoa of the digestive canal 

 of dogs, the Tcenia, even in very great num- 

 bers, very seldom disorder the vital func- 

 tions. 



During a year, we have examined the 

 blood of from seventy to eighty dogs, with- 

 out meeting with the Filaria, and dating 

 from its discovery, we have sought for it, 

 but in vain, in the blood of fifteen dogs. — An-

Remedy for Indigestion. — A friend has 

 handed to us for publication, the annexed 

 remedy for indigestion, a complaint which 

 is so generally prevalent in this country. It 

 was communicated to him by a gentleman 

 in Great Britain, who says in his letter on 

 the subject ; 



" Having suffered much from indigestion, 

 I send you the remedy to relieve you. It 

 arises by rejecting too large a portion of the 

 phosphates of lime and magnesia contained 

 in the bran in making our bread: being quite 

 sure that our all-wise Creator, in giving us 

 wheat for our food to support our frames, 

 placed in it every necessary constituent for 

 the health of them. When, therefore, you 

 derive benefit from it, please to make it 

 known to our brethren in America." 



Boil half a pint of white wheat three hours 

 in a quart of water, or a little more, if ne- 

 cessary. Drink half a pint of the liquid, 

 twice or thrice in a week and the effect will 

 soon be perceived. 



To mahe wholesome bread. — Six ounces 

 of bran boiled one hour and a half in five 

 pints of water; strain the liquid from the 

 bran, and dilute it with water sufficient to 

 make the bread. Two ounces of salt ; five 

 pounds of good flour; two table-spoonfiills 

 of yeast. In baking a larger quantity, each 

 article must be proportionably increased. — U. 

 States Gazette. 



Can't and Won't. — Won''t is a great 

 word for little folks to speak. It don't 

 sound well from tiny lips. But great as it 

 is, the same tiny lips which squeeze it out, 

 are obliged to eat it up again. And it is a 

 hard word to eat. It is a jaw-hreaker, and 

 it don't taste good, neither. Indeed a bitter 

 pill it is. You had better not speak it. It's 

 a saucy word, which will always bring you 

 into trouble. 



But cari't is the lazy boy's word. If you 

 indulge yourself in saying can''t, we fear 

 you will never do anything. You had bet- 

 ter cross it out of your dictionary. Master 

 , CanH will never come to any thing.
