recent brochure by Dr Giacomini. This author appears to have 

 had no opportunity of perusing Pellizzari's communication 

 already cited, and consequently it is not surprising that he should, 

 in common with others, have accepted the original conclusions 

 of Perroncito. Dr Giacomini clearly perceives that, whatever 

 precautions of a hygienic character are suitable for the preven- 

 tion of disease arising out of the consumption of measly pork, 

 the same, or at all events similar, measures ought to be adopted 

 with the view of checking tapeworm affections arising from the 

 ingestion of other kinds of meat, especially veal and beef. Like 

 Pellizzari, he is satisfied as to the human origin of the small 

 bladder worms found in cattle, and establishes this position 

 not only from the oft-quoted experiments of Leuckart and 

 Hosier, but also from those conducted by myself and Simonds 

 in England, and by Professor F. Saint- Cyr in France. From 

 a careful review and consideration of all the facts of the case, 

 he recommended a more complete supervision over the flesh of 

 oxen before it is employed commercially, and greater precaution 

 when employing veal as food, by causing it to be subjected to 

 a high temperature, in order that the parasites may be killed 

 before it is ingested. It is evident that Giacomini thinks that 

 a temperature exceeding that of boiling-point is necessary for 

 the destruction of the beef and veal measles, since he immedi- 

 ately adds, " Though experiments have not been made with the 

 object of ascertaining the amount of resistance of heat which 

 the unarmed cysticercus can bear, yet, judging by those con- 

 ducted by Professor Perroncito on the measle of the hog, we 

 are in a position to say that a temperature of 135 Cent. (275 

 Fahr.) is necessary for the destruction of an isolated Cysticercus, 

 whilst the heat should be raised from 150 to 200 Cent. (302 

 to 392 Fahr.) for ten or fifteen minutes, in order to ensure the 

 complete destruction of the Cysticerci encapsuled in the interior 

 of a piece of meat." I have abridged this portion of Giacomini's 

 text, because his statements are pretty much the same as those 

 already quoted from Perroncito (as cited by Tommasi). But, 

 in the next place, Dr Giacomini is in error when he states that 

 experiments had not been performed on the Cysticerci of the 

 ox. So far from this being the case, similar experiments 

 had long previously been conducted by Dr Lewis in India; 

 and these researches had quite as much to do with the 

 measles or Cysticerci of beef as they had with those of the 

 hog, if not more. Naturally but few foreign investigators can
